3.6 Riverflow Issues
AFFECTED ENVIRONMENT & ENVIRONMENTAL CONSEQUENCES CHAPTER 3 3.6 RIVERFLOW ISSUES 3.6.1 INTRODUCTION This section considers the potential effects of interim surplus criteria on three types of releases from Glen Canyon Dam and Hoover Dam. The Glen Canyon Dam releases analyzed are those needed for restoration of beaches and habitat along the Colorado River between the Glen Canyon Dam and Lake Mead, and for a yet to be defined program of low steady summer flows to be provided for the study and recovery of endangered Colorado River fish, in years when releases from the dam are near the minimum. The Hoover Dam releases analyzed are the frequency of flood releases from the dam and the effect of flood flows along the river downstream of Hoover Dam. 3.6.2 BEACH/HABITAT-BUILDING FLOWS The construction and operation of Glen Canyon Dam has caused two major changes related to sediment resources downstream in Glen Canyon and Grand Canyon. The first is reduced sediment supply. Because the dam traps virtually all of the incoming sediment from the Upper Basin in Lake Powell, the Colorado River is now released from the dam as clear water. The second major change is the reduction in the high water zone from the level of pre-dam annual floods to the level of powerplant releases. Thus, the height of annual sediment deposition and erosion has been reduced. During the investigations leading to the preparation of the Operation of Glen Canyon Dam Final EIS (Reclamation, 1995b), the relationships between releases from the dam and downstream sedimentation processes were brought sharply into focus, and flow patterns designed to conserve sediment for building beaches and habitat (i.e., beach/habitat-building flow, or BHBF releases) were identified. -

THE L\IIEXICALI VALLEY \VATER PROBLEM . Jol-IN C
THE l\IIEXICALI VALLEY \VATER PROBLEM . JOl-IN c. ARCHBOLD San Diego City Schools The Mexicali Valley of Baja California has become a prime producer of cotton and one of the world's great processors of raw cotton. General argiculture has flourished, too. Like a phoenix arisen from the desert this region has been reclaimed from the arid conditions that have gripped the entire area since before the white man arrived. Now, salinity left in the soil by draining irrigation waters threatens to wipe out the progress of half a century. Only salt-tolerant cotton may survive conditions which have become an international issue. North of the border in the summer of 1961 the U.S. Bureau of Reclamation completed the vVellton-Mohawk Irrigation and Drainage District project. The $14,000,000 drainage system includes 70 deep drain age wells with pumps, and a 50-mile concrete-lined conveyance channel with an outfall on the Gila River above Yuma, Arizona (Figure 1). Drainage water being pumped in the Wellton-Mohawk system is not return Bow in the usual sense of the word, but water accumulated over a long period of tirrie as a result of interior drainage. From before the turn of the century until 1952, Wellton-Mohawk farmers depended upon underground flow of the Gila River for irrigation water.1 The quality of this water was uniformly so poor that it was disclosed in testimony before the United States Senate in 1945 that the irrigated area was down to 8,000 acres (as of 1943; later, even less was in crops) and that samples were taken showing a salt content of 12,000 parts per million.2 In 1952, Colorado River water became available with the completion of the Gila Project. -

B.C.D. 15-23 September 17,2015 Employer Status Determination Baja California Railroad, Inc. (BJRR) BA # 5751 This is the decision of the Railroad Retirement Board regarding the status of Baja California Railroad Inc. (BJRR) as an employer under the Railroad Retirement and Railroad Unemployment Insurance Acts, collectively known as the Acts. The status of this company has not previously been considered. Information regarding BJRR was submitted by the company’s controller—first Ana Laura Tufo and then Manuel Hernandez. Alejandro de la Torre Martinez is the Chief Executive Officer and owns the company along with Fernando Beltran and Fernando Cano. There are no affiliated companies. BJRR has offices in San Diego, California and Tijuana, Mexico. It is a short line operator located in the international border region of San Diego, California and Baja California, Mexico. The BJRR stretches 71 kilometers from the San Ysidro, Califomia-Tijuana, Mexico port of entry to the city of Tecate, Mexico. BJRR interchanges at the San Ysidro rail yard with the San Diego and Imperial Valley Railroad, a covered employer under the Acts (BA No. 3758). BJRR interchanges solely with the San Diego and Imperial Valley Railroad. BJRR runs approximately lA mile in the United States and then goes southbound through customs and into Mexico providing rail freight services to customers from various industries such as gas, construction, food, and manufacturing. All deliveries are made in Mexico. The annual volume is approximately 4,500 carloads of exports to Mexico. Section 1(a)(1) of the Railroad Retirement Act (RRA) (45 U.S.C. -
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. -
