The Colorado River is one of the most important water systems in the United States. Draining watersheds from seven western states, it is divided into two major districts, the Upper Basin comprised of Wyoming, Colorado, Utah, and New Mexico, and the Lower Basin formed by Nevada, Arizona, and California. With its headwaters in Wyoming and Colorado and its mouth (until recently) flowing into the Gulf of California, this river serves as a focal point for both prehistoric and historic events in the West.
Yehor Dadiveren, 9-G The Colorado River is one of the principal rivers of the Southwestern United States and northern Mexico.
The length of the Colorado River is approximately 2,330 kilometers (1,450 miles).
The Colorado River flows through seven states, five U.S states, and two mexican states. It flows through Colorado, Utah, Arizona, Nevada, California, Baja California, and Sonora.The Colorado River has an average depth of about 6 meters (20 feet).The name Colorado originates from the Spanish word for red color. The river is home to one of the seven natural wonders of the world, the Grand Canyon. http://justfunfacts.com/interesting-facts-about-the-colorado-river/ Kyiv, Ukraine
During the 16th century, the Spanish began to explore and colonize western North America. An early motive was the search for the Seven Cities of Gold, or "Cibola", rumored to have been built by Native Americans somewhere in the desert Southwest. According to a United States Geological Survey publication, it is likely that Francisco de Ulloa was the first European to see the Colorado River when in 1536 he sailed to the head of the Gulf of California.[141] Francisco Vásquez de Coronado's 1540–1542 expedition began as a search for the fabled Cities of Gold, but after learning from natives in New Mexico of a large river to the west, he sent García López de Cárdenas to lead a small contingent to find it. With the guidance of Hopi Indians, Cárdenas and his men became the first outsiders to see the Grand Canyon.[142] Cárdenas was reportedly unimpressed with the canyon, assuming the width of the Colorado River at 6 feet (1.8 m) and estimating 300-foot (91 m)-tall rock formations to be the size of a man. After failing at an attempt to descend to the river, they left the area, defeated by the difficult terrain and torrid weather.i love use
The Colorado River is by far the largest source of surface water for a thirsty land. About five million years ago its silt-filled waters carved the Grand Canyon and formed the spectacular Gore, Glenwood, De Beque, Glen, and Cataract Canyons. Settlements on the Colorado Plateau have relied on the river for approximately 12,000 years. Today it is the main water source for 25 million people. Formed in Colorado’s Rocky Mountain National Park, the Colorado snakes 1,450 miles through five states and is tamed by over seven dams. Every river in Arizona drains into the Colorado or one of its tributaries. This mighty river used to flow into the Gulf of California after reaching its delta in Mexico—a delta that supported hundreds of animal and plant species. The Colorado River has reached its delta only five times since 1983.

The Colorado River is important to many Native American communities surrounding Grand Canyon National Park. For over 12,000 years, the river has been an important source of water and life for indigenous groups living in and around this vast canyon. Indigenous groups used the river’s water for agriculture and to fortify their lives in the canyon and along the rim. Cities and farms in the arid Southwest draw heavily from the Colorado River. More water is exported from the Colorado River than from any other river in the United States. Cities such as Los Angeles, Phoenix, Las Vegas, Denver, San Diego and many other communities draw water from the Colorado River basin for municipal and industrial uses. In addition, 2 million acres of land are irrigated by water from the Colorado River. http://www.grcahistory.org/history_coloradoriver.html
The Colorado River is one of the principal rivers of the Southwestern United States and northern Mexico (the other being the Rio Grande). The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people.[6] The river and its tributaries are controlled by an extensive system of dams, reservoirs, and aqueducts, which in most years divert its entire flow for agricultural irrigation and domestic water supply.[7][8] Its large flow and steep gradient are used for generating hydroelectric power, and its major dams regulate peaking power demands in much of the Intermountain West. Intensive water consumption has dried up the lower 100 miles (160 km) of the river, which has rarely reached the sea since the 1960s.[7][9][10]
Beginning with small bands of nomadic hunter-gatherers, Native Americans have inhabited the Colorado River basin for at least 8,000 years. Between 2,000 and 1,000 years ago, the watershed was home to large agricultural civilizations – considered some of the most sophisticated indigenous North American cultures – which eventually declined due to a combination of severe drought and poor land use practices. Most native peoples that inhabit the region today are descended from other groups that settled there beginning about 1,000 years ago. Europeans first entered the Colorado Basin in the 16th century, when explorers from Spain began mapping and claiming the area, which became part of Mexico upon its independence in 1821. Early contact between Europeans and Native Americans was generally limited to the fur trade in the headwaters and sporadic trade interactions along the lower river.
After most of the Colorado River basin became part of the U.S. in 1846, much of the river's course was still the subject of myths and speculation. Several expeditions charted the Colorado in the mid-19th century – one of which, led by John Wesley Powell, was the first to run the rapids of the Grand Canyon. American explorers collected valuable information that was later used to develop the river for navigation and water supply. Large-scale settlement of the lower basin began in the mid- to late-19th century, with steamboats providing transportation from the Gulf of California to landings along the river that linked to wagon roads to the interior. Starting in the 1860s, gold and silver strikes drew prospectors to parts of the upper Colorado River basin.
Large engineering works began around the start of the 20th century, with major guidelines established in a series of international and U.S. interstate treaties known as the "Law of the River". The U.S. federal government was the main driving force behind the construction of dams and aqueducts, although many state and local water agencies were also involved. Most of the major dams were built between 1910 and 1970; the system keystone, Hoover Dam, was completed in 1935. The Colorado is now considered among the most controlled and litigated rivers in the world, with every drop of its water fully allocated.

Colorado River, major river of North America, rising in the Rocky Mountains of Colorado, U.S., and flowing generally west and south for 1,450 miles (2,330 kilometres) into the Gulf of California in northwestern Mexico. Its drainage basin covers 246,000 square miles (637,000 square kilometres) and includes parts of seven states—Wyoming, Colorado, Utah, New Mexico, Nevada, Arizona, and California. For 17 miles the river forms the international boundary between the U.S. state of Arizona and Mexico. The river drains a vast arid and semiarid sector of the North American continent, and because of its intensive development it is often referred to as the “Lifeline of the Southwest.”
The modern period began with Spanish exploration and settlement from the mid-16th century, which yielded brief descriptions of the Colorado but no permanent settlements such as those along the upper Rio Grande. Prior to the Civil War, American surveyors focused on routes, passes, and territorial boundaries. With the help of Indian scouts, they acquired enough information to map the river and its main tributaries. Mormons settled the Great Basin of Utah in 1847, moved quickly into tributary valleys of the Colorado in Utah and Arizona, and acquired knowledge that contributed to later scientific surveys.
Inland-shipping entrepreneurs such as Joseph Christmas Ives assessed the navigability of the river as early as 1858. The federal government sponsored major scientific surveys in the 1870s. John Wesley Powell’s dangerous yet spectacular exploration of Colorado River canyons (1869 and 1871–72) was the most celebrated and the first to concentrate directly on the river. Powell’s account combines vivid descriptions of geologic formations, rapids, and Indian cultures. George Wheeler’s survey report of 1889 estimated the velocity and discharge of the river. After 1900, investigations would focus on issues of river development: flood control, irrigation, hydropower, and water supply.
The Colorado falls some 10,000 feet on its way from the Rocky Mountains to the Gulf of California [see Colorado River Facts]. From its headwaters northwest of Denver, the 1,450-mile long river and its tributaries pass through parts of seven states: Arizona, California, Colorado, New Mexico, Nevada, Utah and Wyoming and is also used by the Republic of Mexico.
The Colorado River runs for about 300 miles through Marble Canyon and the Grand Canyon. The powerful forces of erosion have carved through 2 billion years of the earth’s geologic history at the Grand Canyon. Layers of limestone, sandstone, shale, granite, and schist make up the Grand Canyon’s rock sequences.
Hello !!! I'm Ruslana Shymohina from 9-A class I want to tell about Colorado River .
The Colorado River's name is Spanish for the "color red" referring to the river's muddy color, but Colorado was just the final in the long line of labels this iconic river has worn over the years. Originally the 16th century Spaniard explorers called the river Rio del Tizon, which translated to mean River of Embers or Firebrand River and supposedly described a practice local natives used to warm themselves. Later, some maps named the river the Rio Colorado de los Martyrs and the El Rio de Cosminas de Rafael, again names that indicate the characteristic red of the water coupled with reference to martyrs and Rafael, perhaps Saint Rafael, but the specifics of these names are unknown.
The first humans of the Colorado River basin were likely Paleo-Indians of the Clovis and Folsom cultures, who first arrived on the Colorado Plateau about 12,000 years ago. Very little human activity occurred in the watershed until the rise of the Desert Archaic Culture, which from 8,000 to 2,000 years ago constituted most of the region's human population. These prehistoric inhabitants led a generally nomadic lifestyle, gathering plants and hunting small animals (though some of the earliest peoples hunted larger mammals that became extinct in North America after the end of the Pleistocene epoch) Dubyk Andriy
To talk about the Colorado River’s present and future, you need to start in the past. One of the most important dates in the river’s history is Nov. 24, 1922, when leaders from the seven Western states that rely on the river met at a Santa Fe, New Mexico resort to sign the Colorado River Compact.
“It’s the cornerstone of how we allocate water on the Colorado River,” Mueller says. “On that cornerstone is built an incredible scaffolding of complex agreements, but it’s all based on that 1922 compact.”
Pilloried for decades for its structural problems, the compact did accomplish a few basic things. To make it easier to govern, the agreement divided the river into halves: the Upper and Lower Basins. The Upper Basin includes the snowy Rocky Mountain states of Colorado, Wyoming, Utah and New Mexico. The Lower is home to the desert landscapes of Arizona, Nevada and California.
Engineers used stream gauge data to estimate the river’s annual flow and the politicians took those measurements to divide the water amongst themselves. Each basin got 7.5 million acre-feet (one acre-foot is enough water to supply about two households annually) and each state within the basin got a portion of the water. California then and today is the largest user of Colorado River water.
California’s use of the river’s water is what brought these political figures together in the first place, Mueller says. Concerns about the state’s rapid development were growing louder. If the whole watershed functioned under the frontier water law doctrine of prior appropriation (where the person who claims the water first is given priority in receiving it) California could end up owning every drop.
“The reality is that the Lower Basin had the upper hand in those negotiations,” Mueller says. “They were developing faster.”
To get a deal, the Upper Basin agreed that Lower Basin states would be guaranteed a certain amount of water right at the line that divides their two regions. Some years would be wetter, some would be drier, but the decade-long rolling average couldn’t dip below 75 million acre feet of water, measured at a spot just below Glen Canyon Dam in northern Arizona. If it did drop below that point, then the Lower Basin could come calling for its water.
This system works fine when there’s enough water to go around. But that’s the signature bug of the Colorado River: More water exists on paper than in reality.http://www.kunc.org/post/colorado-river-water-managers-can-imagine-future-and-it-doesn-t-look-pretty#stream/0 Valeriia Kalchenko Ukrain, Kiev

The Colorado River is the largest water artery of North America, with a length of 2330 km and a total water basin of 629 thousand square meters. km The river is mapped on two states: the USA and Mexico. The Colorado River is mapped on two states: it begins its origin in the Rocky Mountains in the state of Colorado (southwestern United States) and follows into the California Bay of the Pacific Ocean (northern Mexico), where once formed a large-scale delta. Now the Colorado River in Mexico has become shallow, and even in high water years it rarely reaches the boundaries of the Pacific Ocean. Only 4% of water reaches the delta.
Its name - Colorado (with the Spanish. "Red") - the river received as a result of a casus error. The first colonizers of these lands, the Spaniards, when drawing up the map, mixed up Colorado with another river - Brazos, whose waters had a red tint due to brown silty sediments.
The Colorado courses through Utah in a southwesterly direction and has two major tributaries, the Green and San Juan rivers, with smaller, additional sources flowing in from east and west. During prehistoric times it constituted a permeable boundary between the Anasazi populations to the south and east, and the Fremont and western Anasazi populations to the northwest and west, respectively. The Anasazi farmed tributary canyons and alluvial bottom lands where soil was rich and water adequate. These early Indians also created a system of trails that crossed both the San Juan and Colorado rivers. Spanish and Anglo-Americans later used some of these paths in their exploration and settlement of the West.
Historic Native American groups living along the Colorado include the Paiute in southwestern Utah, the Ute in southeastern Utah, and the Navajo south and east of the confluence of the San Juan and the Colorado. This latter group has a rich body of lore concerning the river, which they say has a female spirit name "Life Without End." She, and her male counterpart, the San Juan, form a protective boundary that skirts the reservation lands. In the past, Navajo ceremonies like the Blessingway provided protection for events and locations within this area, while beyond this line Enemyway and Evilway applied. Navajo raids across these rivers were a common occurrence during the 1850s and 1860s, and to a lesser extent in the 1870s. https://historytogo.utah.gov/utah_chapters/the_land/coloradoriver.html Ira Kolisnichenko 9-V Kyiv, Ukraine
The name Colorado originates from the Spanish word for red color. This is because of the red sandstone silt that would cover the river basin, making it look red. One of the nicknames given to this river is River Of Law, because of the high number of legal disagreements over its water. Now, nearly all the water of the river is controlled.
The Colorado River is 1,450 miles (2,330 km) long and roughly 300 feet wide. It flows through 7 states, Colorado, New Mexico, Utah, Arizona, Wyoming, California, and Nevada.
The earliest settlers along the Colorado River Basin are believed to be the Paleo-Indians, who belonged to the Clovis and other cultures. They are estimated to have landed up at this location over 12,000 years ago. Its water has been subject to many fights and wars among the states that it flows through, making legislation necessary. Today, it is also used by many people as an adventure and recreation location. https://vacayholics.com/interesting-facts-about-colorado-river

From 1700-1800, the upper reaches of the river were under the control of the tribes of the commander. In 1757, Spanish Texas sent a Catholic mission to the place where the rivers of Colorado and San Baba met. Commanders aggressively met the missionaries. They took their visit as an attempt to seize the territory. In 1758, the commanders destroyed the entire mission of the unarmed Catholics. It will take another century before the white people again venture to invade the team. http://proukrtravel.ru/rizne/10688-richka-kolorado.html Artur Luesin 9-B Kiev, Ukraine

Even Hite City (1883), named after Cass Hite, a prominent prospector, was a boom-and-bust mining town on the Colorado that lasted only seven years. After the placer gold was removed from the gravel bars located at sites like Dandy's Crossing and Ticaboo, the miners left their claims in search of better paydirt. Few were truly successful. Men with gold in their dreams again ventured forth in the 1890s. For about ten years, individual miners and companies with dredges tried to force riches out of the San Juan and Colorado rivers, but achieved little wealth. They, like the others, left.
The 1930s and 1940s saw the introduction of a more profitable trade on the Colorado--river running and tourism. Norman Nevills, for example, headquartered at Mexican Hat and turned the red waters of the San Juan and Colorado into green cash as recreation became increasingly important. Even with the introduction of the Glen Canyon Dam in the 1950s and Lake Powell in the 1960s, there was still plenty of white water and red rock for adventurous souls to find the isolation and excitement they desired. And later, when its tributaries were heavily committed to irrigation and culinary use, the Colorado remained a playground for kayakers, rafters, and tourists. Today, the Utah portion of the Colorado River continues to offer not only its water as a resource, but also its beauty and adventure to those who come to its banks.
9-V The Colorado River is 1450 miles in length. The river flows through seven U.S. states (including, Colorado, Utah, Arizona, Nevada and California) and two Mexican states. Its source in La Poudre Pass in Rocky Mountains, and it flows into the Sea of Cortez at the Gulf of California, between the Mexican states, Baja California and Sonora. The Colorado River supplies water to more than 25 million people. It is also responsible for irrigating 3.5 million acres of farmland. The Colorado River is home to one of the seven natural wonders of the world, the Grand Canyon. There are eleven U.S. national parks along the Colorado River. The biggest sport along the Colorado River is whitewater rafting. Several sections of the river are used, including Westwater Canyon, Fisher Towers, Cataract Canyon and the Grand Canyon. Most of the major dams along the Colorado River basin were built between 1910 and 1970. One of the most well-known is the Hoover Dam which was built in 1935. The river was nicknamed the River of Law because of all the legal disputes that have involved the flow of the river and its water over the years. It is now one of the most highly controlled rivers in the world. Ukraine

The Colorado is the premier river of the American Southwest. Rising in the mountains of Colorado and Wyoming, this river and its tributaries provide water and hydroelectric power for nearly 35 million people in the United States and Mexico, as well as habitat for several fish species found only in this drainage basin. Human use of water has severely altered the river, however, leading one writer to describe it as “a river no more.” The combined effects of numerous dams and extensive diversions of water from the river have so significantly altered natural flows that many of the plants and animals native to the river are gradually disappearing from the drainage basin, and most years the river no longer reaches the Pacific Ocean.
The year 1997 marks the 75th anniversary of the signing of the Colorado River Compact. Delegates from the seven Colorado River Basin states met on November 9, 1922, in New Mexico to discuss, negotiate and ultimately work out the compact. It was then signed in the Palace of the Governors, Santa Fe, on November 24. The compact apportioned Colorado River water between Upper and Lower Basin states and, as a result, is considered a defining document in Colorado River management.
As a measure of its importance and stature, the compact became the keystone to the "Law of the River."The Law of the River is a composite some might say an "assortment" to better describe its piecemeal assemblage of state and federal laws and regulations, court decisions, and international treaties made over time for the purpose of managing the Colorado River. Concerned with one of the West's most important rivers, the compact clearly stands as a monument in U. S western water law.
Culture : The culture of the Colorado river is very unique. It goes back to the time of the Indians, especially the Blackfoot tribe. Desert people also lived alongside the Colorado river. They revered it, thinking the water to be sacred. The Blackfoot tribe of Indians also felt this way about water. Native Americans view nature by belief, a body of water is not only able to sustain life, but it was sacred to the Indians, which is a much different theory than most Americans believe these days. They seem to know that we need water, yet trash can be found in most all rivers. The water was believed sacred by this tribe because it was considered one of the three separate realms, the water realm. Within these three realms lived the “divine” beings. However, the water realm was believed even more so special because it not only had divine beings, it had divine animals. The divine beaver taught the Blackfoot tribe their most important religious ceremony. We should try to follow the Blackfeet policy, which is never to kill or eat anything in the water, and most importantly, not to disturb or pollute the water.
History by Julianna : The river was first mapped in the early 1600s by Francisco de Bolanos, from the mouth all the way to the Gulf of California, 19th Century Further expeditions fully mapped the river in the years between 1869 and 1872, and a 30-foot ferry was built in Utah by Mormons and other settlers. 1890s to 1930s The river became a popular place for miners, travelers and tourists At the end of the 19th century, towns and outposts began to expand around the river, slowly surrounding states. 1960s and 1970s A series of canals and aqueducts were constructed on the Colorado River and its tributaries, dividing the water to such essential cities as Los Angeles, Las Vegas, Phoenix, Tucson, Arizona etc.

Water Use: Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes, dishes, brushing your teeth, watering the yard and garden, and even washing the dog. Water generally gets to our homes in one of two ways. Either it is delivered by a city/county water department (or maybe from a private company), or people supply their own water, normally from a well. Water delivered to homes is called "public-supplied deliveries" and water that people supply themselves is called "self supplied", and is almost always from groundwater.
The majority of America's population gets their water delivered from a public-supply system. This makes sense, as America's population now largely live in urban centers. The trend over the last 70 years is of people moving to urban centers and is reflected in the shrinking numbers of self-supplied people in the Nation.

ReplyDeleteThe Colorado River is one of the most important water systems in the United States. Draining watersheds from seven western states, it is divided into two major districts, the Upper Basin comprised of Wyoming, Colorado, Utah, and New Mexico, and the Lower Basin formed by Nevada, Arizona, and California. With its headwaters in Wyoming and Colorado and its mouth (until recently) flowing into the Gulf of California, this river serves as a focal point for both prehistoric and historic events in the West.

ReplyDeleteDuring the 16th century, the Spanish began to explore and colonize western North America. An early motive was the search for the Seven Cities of Gold, or "Cibola", rumored to have been built by Native Americans somewhere in the desert Southwest. According to a United States Geological Survey publication, it is likely that Francisco de Ulloa was the first European to see the Colorado River when in 1536 he sailed to the head of the Gulf of California.[141] Francisco Vásquez de Coronado's 1540–1542 expedition began as a search for the fabled Cities of Gold, but after learning from natives in New Mexico of a large river to the west, he sent García López de Cárdenas to lead a small contingent to find it. With the guidance of Hopi Indians, Cárdenas and his men became the first outsiders to see the Grand Canyon.[142] Cárdenas was reportedly unimpressed with the canyon, assuming the width of the Colorado River at 6 feet (1.8 m) and estimating 300-foot (91 m)-tall rock formations to be the size of a man. After failing at an attempt to descend to the river, they left the area, defeated by the difficult terrain and torrid weather.i love use

ReplyDeleteThe Colorado River is by far the largest source of surface water for a thirsty land. About five million years ago its silt-filled waters carved the Grand Canyon and formed the spectacular Gore, Glenwood, De Beque, Glen, and Cataract Canyons. Settlements on the Colorado Plateau have relied on the river for approximately 12,000 years. Today it is the main water source for 25 million people. Formed in Colorado’s Rocky Mountain National Park, the Colorado snakes 1,450 miles through five states and is tamed by over seven dams. Every river in Arizona drains into the Colorado or one of its tributaries. This mighty river used to flow into the Gulf of California after reaching its delta in Mexico—a delta that supported hundreds of animal and plant species. The Colorado River has reached its delta only five times since 1983.

The Colorado River is important to many Native American communities surrounding Grand Canyon National Park. For over 12,000 years, the river has been an important source of water and life for indigenous groups living in and around this vast canyon. Indigenous groups used the river’s water for agriculture and to fortify their lives in the canyon and along the rim.
Cities and farms in the arid Southwest draw heavily from the Colorado River. More water is exported from the Colorado River than from any other river in the United States. Cities such as Los Angeles, Phoenix, Las Vegas, Denver, San Diego and many other communities draw water from the Colorado River basin for municipal and industrial uses. In addition, 2 million acres of land are irrigated by water from the Colorado River.

The Colorado River is one of the principal rivers of the Southwestern United States and northern Mexico (the other being the Rio Grande). The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
ReplyDeleteKnown for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people.[6] The river and its tributaries are controlled by an extensive system of dams, reservoirs, and aqueducts, which in most years divert its entire flow for agricultural irrigation and domestic water supply.[7][8] Its large flow and steep gradient are used for generating hydroelectric power, and its major dams regulate peaking power demands in much of the Intermountain West. Intensive water consumption has dried up the lower 100 miles (160 km) of the river, which has rarely reached the sea since the 1960s.[7][9][10]
Beginning with small bands of nomadic hunter-gatherers, Native Americans have inhabited the Colorado River basin for at least 8,000 years. Between 2,000 and 1,000 years ago, the watershed was home to large agricultural civilizations – considered some of the most sophisticated indigenous North American cultures – which eventually declined due to a combination of severe drought and poor land use practices. Most native peoples that inhabit the region today are descended from other groups that settled there beginning about 1,000 years ago. Europeans first entered the Colorado Basin in the 16th century, when explorers from Spain began mapping and claiming the area, which became part of Mexico upon its independence in 1821. Early contact between Europeans and Native Americans was generally limited to the fur trade in the headwaters and sporadic trade interactions along the lower river.
After most of the Colorado River basin became part of the U.S. in 1846, much of the river's course was still the subject of myths and speculation. Several expeditions charted the Colorado in the mid-19th century – one of which, led by John Wesley Powell, was the first to run the rapids of the Grand Canyon. American explorers collected valuable information that was later used to develop the river for navigation and water supply. Large-scale settlement of the lower basin began in the mid- to late-19th century, with steamboats providing transportation from the Gulf of California to landings along the river that linked to wagon roads to the interior. Starting in the 1860s, gold and silver strikes drew prospectors to parts of the upper Colorado River basin.
Large engineering works began around the start of the 20th century, with major guidelines established in a series of international and U.S. interstate treaties known as the "Law of the River". The U.S. federal government was the main driving force behind the construction of dams and aqueducts, although many state and local water agencies were also involved. Most of the major dams were built between 1910 and 1970; the system keystone, Hoover Dam, was completed in 1935. The Colorado is now considered among the most controlled and litigated rivers in the world, with every drop of its water fully allocated.

ReplyDeleteColorado River, major river of North America, rising in the Rocky Mountains of Colorado, U.S., and flowing generally west and south for 1,450 miles (2,330 kilometres) into the Gulf of California in northwestern Mexico. Its drainage basin covers 246,000 square miles (637,000 square kilometres) and includes parts of seven states—Wyoming, Colorado, Utah, New Mexico, Nevada, Arizona, and California. For 17 miles the river forms the international boundary between the U.S. state of Arizona and Mexico. The river drains a vast arid and semiarid sector of the North American continent, and because of its intensive development it is often referred to as the “Lifeline of the Southwest.”
The modern period began with Spanish exploration and settlement from the mid-16th century, which yielded brief descriptions of the Colorado but no permanent settlements such as those along the upper Rio Grande. Prior to the Civil War, American surveyors focused on routes, passes, and territorial boundaries. With the help of Indian scouts, they acquired enough information to map the river and its main tributaries. Mormons settled the Great Basin of Utah in 1847, moved quickly into tributary valleys of the Colorado in Utah and Arizona, and acquired knowledge that contributed to later scientific surveys.
Inland-shipping entrepreneurs such as Joseph Christmas Ives assessed the navigability of the river as early as 1858. The federal government sponsored major scientific surveys in the 1870s. John Wesley Powell’s dangerous yet spectacular exploration of Colorado River canyons (1869 and 1871–72) was the most celebrated and the first to concentrate directly on the river. Powell’s account combines vivid descriptions of geologic formations, rapids, and Indian cultures. George Wheeler’s survey report of 1889 estimated the velocity and discharge of the river. After 1900, investigations would focus on issues of river development: flood control, irrigation, hydropower, and water supply.

I want to tell about Colorado River .
The Colorado River's name is Spanish for the "color red" referring to the river's muddy color, but Colorado was just the final in the long line of labels this iconic river has worn over the years. Originally the 16th century Spaniard explorers called the river Rio del Tizon, which translated to mean River of Embers or Firebrand River and supposedly described a practice local natives used to warm themselves. Later, some maps named the river the Rio Colorado de los Martyrs and the El Rio de Cosminas de Rafael, again names that indicate the characteristic red of the water coupled with reference to martyrs and Rafael, perhaps Saint Rafael, but the specifics of these names are unknown.

The first humans of the Colorado River basin were likely Paleo-Indians of the Clovis and Folsom cultures, who first arrived on the Colorado Plateau about 12,000 years ago. Very little human activity occurred in the watershed until the rise of the Desert Archaic Culture, which from 8,000 to 2,000 years ago constituted most of the region's human population. These prehistoric inhabitants led a generally nomadic lifestyle, gathering plants and hunting small animals (though some of the earliest peoples hunted larger mammals that became extinct in North America after the end of the Pleistocene epoch)

The ‘cornerstone’
ReplyDeleteTo talk about the Colorado River’s present and future, you need to start in the past. One of the most important dates in the river’s history is Nov. 24, 1922, when leaders from the seven Western states that rely on the river met at a Santa Fe, New Mexico resort to sign the Colorado River Compact.
“It’s the cornerstone of how we allocate water on the Colorado River,” Mueller says. “On that cornerstone is built an incredible scaffolding of complex agreements, but it’s all based on that 1922 compact.”
Pilloried for decades for its structural problems, the compact did accomplish a few basic things. To make it easier to govern, the agreement divided the river into halves: the Upper and Lower Basins. The Upper Basin includes the snowy Rocky Mountain states of Colorado, Wyoming, Utah and New Mexico. The Lower is home to the desert landscapes of Arizona, Nevada and California.
Engineers used stream gauge data to estimate the river’s annual flow and the politicians took those measurements to divide the water amongst themselves. Each basin got 7.5 million acre-feet (one acre-foot is enough water to supply about two households annually) and each state within the basin got a portion of the water. California then and today is the largest user of Colorado River water.
California’s use of the river’s water is what brought these political figures together in the first place, Mueller says. Concerns about the state’s rapid development were growing louder. If the whole watershed functioned under the frontier water law doctrine of prior appropriation (where the person who claims the water first is given priority in receiving it) California could end up owning every drop.
“The reality is that the Lower Basin had the upper hand in those negotiations,” Mueller says. “They were developing faster.”
To get a deal, the Upper Basin agreed that Lower Basin states would be guaranteed a certain amount of water right at the line that divides their two regions. Some years would be wetter, some would be drier, but the decade-long rolling average couldn’t dip below 75 million acre feet of water, measured at a spot just below Glen Canyon Dam in northern Arizona. If it did drop below that point, then the Lower Basin could come calling for its water.
This system works fine when there’s enough water to go around. But that’s the signature bug of the Colorado River: More water exists on paper than in reality.http://www.kunc.org/post/colorado-river-water-managers-can-imagine-future-and-it-doesn-t-look-pretty#stream/0

The Colorado River
ReplyDeleteThe Colorado River is the largest water artery of North America, with a length of 2330 km and a total water basin of 629 thousand square meters. km The river is mapped on two states: the USA and Mexico. The Colorado River is mapped on two states: it begins its origin in the Rocky Mountains in the state of Colorado (southwestern United States) and follows into the California Bay of the Pacific Ocean (northern Mexico), where once formed a large-scale delta. Now the Colorado River in Mexico has become shallow, and even in high water years it rarely reaches the boundaries of the Pacific Ocean. Only 4% of water reaches the delta.
Its name - Colorado (with the Spanish. "Red") - the river received as a result of a casus error. The first colonizers of these lands, the Spaniards, when drawing up the map, mixed up Colorado with another river - Brazos, whose waters had a red tint due to brown silty sediments.

The Colorado courses through Utah in a southwesterly direction and has two major tributaries, the Green and San Juan rivers, with smaller, additional sources flowing in from east and west. During prehistoric times it constituted a permeable boundary between the Anasazi populations to the south and east, and the Fremont and western Anasazi populations to the northwest and west, respectively. The Anasazi farmed tributary canyons and alluvial bottom lands where soil was rich and water adequate. These early Indians also created a system of trails that crossed both the San Juan and Colorado rivers. Spanish and Anglo-Americans later used some of these paths in their exploration and settlement of the West.
ReplyDeleteHistoric Native American groups living along the Colorado include the Paiute in southwestern Utah, the Ute in southeastern Utah, and the Navajo south and east of the confluence of the San Juan and the Colorado. This latter group has a rich body of lore concerning the river, which they say has a female spirit name "Life Without End." She, and her male counterpart, the San Juan, form a protective boundary that skirts the reservation lands. In the past, Navajo ceremonies like the Blessingway provided protection for events and locations within this area, while beyond this line Enemyway and Evilway applied. Navajo raids across these rivers were a common occurrence during the 1850s and 1860s, and to a lesser extent in the 1870s.

The Colorado is the premier river of the American Southwest. Rising in the mountains of Colorado and Wyoming, this river and its tributaries provide water and hydroelectric power for nearly 35 million people in the United States and Mexico, as well as habitat for several fish species found only in this drainage basin. Human use of water has severely altered the river, however, leading one writer to describe it as “a river no more.” The combined effects of numerous dams and extensive diversions of water from the river have so significantly altered natural flows that many of the plants and animals native to the river are gradually disappearing from the drainage basin, and most years the river no longer reaches the Pacific Ocean.

Delegates from the seven Colorado River Basin states met on November 9, 1922, in New Mexico to discuss, negotiate and ultimately work out the compact. It was then signed in the Palace of the Governors, Santa Fe, on November 24. The compact apportioned Colorado River water between Upper and Lower Basin states and, as a result, is considered a defining document in Colorado River management.
As a measure of its importance and stature, the compact became the keystone to the "Law of the River."The Law of the River is a composite some might say an "assortment" to better describe its piecemeal assemblage of state and federal laws and regulations, court decisions, and international treaties made over time for the purpose of managing the Colorado River. Concerned with one of the West's most important rivers, the compact clearly stands as a monument in U. S western water law.

The Colorado River
ReplyDeleteCulture :
The culture of the Colorado river is very unique. It goes back to the time of the Indians, especially the Blackfoot tribe. Desert people also lived alongside the Colorado river. They revered it, thinking the water to be sacred. The Blackfoot tribe of Indians also felt this way about water. Native Americans view nature by belief, a body of water is not only able to sustain life, but it was sacred to the Indians, which is a much different theory than most Americans believe these days. They seem to know that we need water, yet trash can be found in most all rivers. The water was believed sacred by this tribe because it was considered one of the three separate realms, the water realm. Within these three realms lived the “divine” beings. However, the water realm was believed even more so special because it not only had divine beings, it had divine animals. The divine beaver taught the Blackfoot tribe their most important religious ceremony. We should try to follow the Blackfeet policy, which is never to kill or eat anything in the water, and most importantly, not to disturb or pollute the water.
History by Julianna : The river was first mapped in the early 1600s by Francisco de Bolanos, from the mouth all the way to the Gulf of California, 19th Century
Further expeditions fully mapped the river in the years between 1869 and 1872, and a 30-foot ferry was built in Utah by Mormons and other settlers. 1890s to 1930s
The river became a popular place for miners, travelers and tourists At the end of the 19th century, towns and outposts began to expand around the river, slowly
surrounding states. 1960s and 1970s
A series of canals and aqueducts were constructed on the Colorado River and its tributaries, dividing the water to such essential cities as Los Angeles, Las Vegas, Phoenix, Tucson, Arizona etc.

Pollution is killing fish, and other plant life. It has devastated our earth. If you still want to fish with your mother or father in 20 years, save the rivers!
Water Use:
Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes, dishes, brushing your teeth, watering the yard and garden, and even washing the dog. Water generally gets to our homes in one of two ways. Either it is delivered by a city/county water department (or maybe from a private company), or people supply their own water, normally from a well. Water delivered to homes is called "public-supplied deliveries" and water that people supply themselves is called "self supplied", and is almost always from groundwater.
The majority of America's population gets their water delivered from a public-supply system. This makes sense, as America's population now largely live in urban centers. The trend over the last 70 years is of people moving to urban centers and is reflected in the shrinking numbers of self-supplied people in the Nation.
