Management of the Colorado River: Water Allocations, Drought, and the Federal Role
Management of the Colorado River: Water Allocations, Drought, and the Federal Role Updated March 21, 2019 Congressional Research Service https://crsreports.congress.gov R45546 SUMMARY R45546 Management of the Colorado River: Water March 21, 2019 Allocation, Drought, and the Federal Role Charles V. Stern The Colorado River Basin covers more than 246,000 square miles in seven U.S. states Specialist in Natural (Wyoming, Colorado, Utah, New Mexico, Arizona, Nevada, and California) and Resources Policy Mexico. Pursuant to federal law, the Bureau of Reclamation (part of the Department of the Interior) manages much of the basin’s water supplies. Colorado River water is used Pervaze A. Sheikh primarily for agricultural irrigation and municipal and industrial (M&I) uses, but it also Specialist in Natural is important for power production, fish and wildlife, and recreational uses. Resources Policy In recent years, consumptive uses of Colorado River water have exceeded natural flows. This causes an imbalance in the basin’s available supplies and competing demands. A drought in the basin dating to 2000 has raised the prospect of water delivery curtailments and decreased hydropower production, among other things. In the future, observers expect that increasing demand for supplies, coupled with the effects of climate change, will further increase the strain on the basin’s limited water supplies. River Management The Law of the River is the commonly used shorthand for the multiple laws, court decisions, and other documents governing Colorado River operations. The foundational document of the Law of the River is the Colorado River Compact of 1922. Pursuant to the compact, the basin states established a framework to apportion the water supplies between the Upper and Lower Basins of the Colorado River, with the dividing line between the two basins at Lee Ferry, AZ (near the Utah border).

ATTACHMENT B Dams and Reservoirs Along the Lower
ATTACHMENTS ATTACHMENT B Dams and Reservoirs Along the Lower Colorado River This attachment to the Colorado River Interim Surplus Criteria DEIS describes the dams and reservoirs on the main stream of the Colorado River from Glen Canyon Dam in Arizona to Morelos Dam along the international boundary with Mexico. The role that each plays in the operation of the Colorado River system is also explained. COLORADO RIVER INTERIM SURPLUS CRITERIA DRAFT ENVIRONMENTAL IMPACT STATEMENT COLORADO RIVER DAMS AND RESERVOIRS Lake Powell to Morelos Dam The following discussion summarizes the dams and reservoirs along the Colorado River from Lake Powell to the Southerly International Boundary (SIB) with Mexico and their specific roles in the operation of the Colorado River. Individual dams serve one or more specific purposes as designated in their federal construction authorizations. Such purposes are, water storage, flood control, river regulation, power generation, and water diversion to Arizona, Nevada, California, and Mexico. The All-American Canal is included in this summary because it conveys some of the water delivered to Mexico and thereby contributes to the river system operation. The dams and reservoirs are listed in the order of their location along the river proceeding downstream from Lake Powell. Their locations are shown on the map attached to the inside of the rear cover of this report. Glen Canyon Dam – Glen Canyon Dam, which formed Lake Powell, is a principal part of the Colorado River Storage Project. It is a concrete arch dam 710 feet high and 1,560 feet wide. The maximum generating discharge capacity is 33,200 cfs which may be augmented by an additional 15,000 cfs through the river outlet works.

Law of the River the Colorado River Compact
Colorado River Water Users Association: Law of the River . The Colorado River Compact . As the 20th century dawned, the The Colorado River Compact vast domain of the Colorado River lay almost entirely Boulder Canyon Project Act untouched. Though there had been a few early filings for Treaty with Mexico diversion and a "grand ditch" conveying water some 16 miles across the Continental Divide Upper Colorado River Basin into eastern Colorado in the late Compact of 1948 1800s, California's Imperial Valley was among the first areas to tap the river's true potential. In early 1901, the 60 mile long Alamo Canal, Colorado River Storage Project developed by private concerns, was completed to deliver Colorado Act River water for irrigation, and a wasteland was transformed. But the Imperial Valley did not move ahead without problems. About 50 miles Grand Canyon Protection Act of the canal coursed through Mexico, leaving the valley farmers at the mercy of a foreign government. And in 1905, the river, raging with Arizona vs. California floods, eroded the opening to the canal, roared through and created the Salton Sea before the river was pushed back into its normal channel. Future of Western Water With the constant threat of flood looming along the lower Colorado, demands grew for some sort of permanent flood control work -a storage reservoir and dam on the river. And Imperial Valley farmers called for a canal totally within the United States, free of Mexican interference. By 1919, Imperial Irrigation District had won the support of the federal Bureau of Reclamation. A bureau engineering board recommended favorably on the canal and added the government "should undertake the early construction of a storage reservoir on the drainage basin of the Colorado." While this report was greeted with enthusiasm by people along the river's lower stretches, it was viewed with alarm by those in upper reaches.

Colorado River Slideshow Title TK
The Colorado River: Lifeline of the Southwest { The Headwaters The Colorado River begins in the Rocky Mountains at elevation 10,000 feet, about 60 miles northwest of Denver in Colorado. The Path Snow melts into water, flows into the river and moves downstream. In Utah, the river meets primary tributaries, the Green River and the San Juan River, before flowing into Lake Powell and beyond. Source: Bureau of Reclamation The Path In total, the Colorado River cuts through 1,450 miles of mountains, plains and deserts to Mexico and the Gulf of California. Source: George Eastman House It was almost 1,500 years ago when humans first tapped the river. Since then, the water has been claimed, reclaimed, divided and subdivided many times. The river is the life source for seven states – Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming – as well as the Republic of Mexico. River Water Uses There are many demands for Colorado River water: • Agriculture and Livestock • Municipal and Industrial • Recreation • Fish/Wildlife and Habitat • Hydroelectricity • Tribes • Mexico Source: USGS Agriculture The Colorado River provides irrigation water to about 3.5 million acres of farmland – about 80 percent of its flows. Municipal Phoenix Denver About 15 percent of Colorado River flows provide drinking and household water to more than 30 million people. These cities include: Las Vegas and Phoenix, and cities outside the Basin – Denver, Albuquerque, Salt Lake City, Los Angeles, San Diego and Tijuana, Mexico. Recreation Source: Utah Office of Tourism Source: Emma Williams Recreation includes fishing, boating, waterskiing, camping and whitewater rafting in 22 National Wildlife Refuges, National Parks and National Recreation Areas along river.

4 The Colorado River: lifeline of the American Southwest Clarence A. Carlson Department of Fishery and Wildlife Biology, Colorado State University, Fort Collins, CO, USA 80523 Robert T. Muth Larval Fish Laboratory, Colorado State University, Fort Collins, CO, USA 80523 1 Carlson, C. A., and R. T. Muth. 1986. The Colorado River: lifeline of the American Southwest. Can. J. Fish. Aguat. Sci. In less than a century, the wild Colorado River has been drastically and irreversibly transformed into a tamed, man-made system of regulated segments dominated by non-native organisms. The pristine Colorado was characterized by widely fluctuating flows and physico-chemical extremes and harbored unique assemblages of indigenous flora and fauna. Closure of Hoover Dam in 1935 marked the end of the free-flowing river. The Colorado River System has since become one of the most altered and intensively controlled in the United States. Many main-stem and tributary dams, water diversions, and channelized river sections now exist in the basin. Despite having one of - the most arid drainages in the world, the present-day Colorado River supplies more water for consumptive use than any river in the United States. Physical modification of streams and introduction of non-native species have adversely impacted the Colorado's native biota. This paper treats the Colorado River holistically as an ecosystem and summarizes current knowledge on its ecology and management. "In a little over two generations, the wild Colorado has been harnessed by a series of dams strung like beads on a thread from the Gulf of California to the mountains of Wyoming.

Ambient Groundwater Quality of Tlie Yuma Basin; an ADEQ 1995 Baseline Study
Ambient Groundwater Quality of tlie Yuma Basin; An ADEQ 1995 Baseline Study I. Introduction The Yuma Groundwater Basin (YGB), located in the southwestern comer of Arizona (Figure 1), is an area of startling geographic contrasts. Precipitation in this arid basin averages less than three inches aimually, yet because of irrigation it is one of the world's most productive agricultural zones. Similarly, much of the YGB is uninhabited desert, yet the basin has a large, growing population that increases seasonally with the arrival of a large winter visitor (snowbird) population. A variety of water-related issues in the basin prompted the Arizona Department of Enviroimiental Quality (ADEQ) to conduct a regional groundwater quality study of the YGB in 1995. This ADEQ factsheet is a summary of the more extensive ADEQ hydrology report available from the agency (1). II. Background The YGB encompasses more than 750 square miles at the apex of the Colorado River delta, approximately 70 miles north of the Gulf of California (2). The basin boundaries are formed by two hydrologic barriers, the Laguna Mountains to the northeast and the Gila and Tinajas Atlas Mountains to the east, and two political boundaries, the Figure 1.

As in presenting any lesson, you first get the students ready to watch the video. Then they watch it. And last you discuss what you watched and perhaps assign work for students to explore the topic further. Learning Outcomes: After watching this video students will know 1. The Imperial Valley had few permanent residents prior to the arrival of irrigation water from the Colorado River in 1901. 2. Prior to the Valley’s settlement, it was repeatedly filled with a giant lake by a meandering Colorado River 3. In the mid-1800s, travelers and scientists realized the Imperial Valley could be irrigated from the Colorado River by gravity. 4. Several of the attempts to bring water to the Imperial Valley failed. 5. Charles Rockwood started the California Development Company and tried for seven years to find funding to bring water. 6. George Chaffey was the one who actually brought water to the Valley in 1901. 7. Before dams were built, the Colorado River had huge variations in flow, and so the California Development Company couldn’t deliver water in early spring without making risky diversions of the Colorado River. 8. In 1905, the Colorado River overflowed its banks and flowed into the Imperial Valley, flooding many settlers’ farms and forming the Salton Sea. 9. The Southern Pacific Railroad took over the California Development Company and spent millions to put the Colorado River back into its channel.
