The upper Colorado River system is the habitat of several endangered fish: Kendall Warm Springs dace, Colorado squawfish, humpback chub, and bonytail chub. The single most important factor contributing to the decline of these species has been the construction and operation of dams and reservoirs, which have effected flow, temperature, chemistry, biota, and migration routes. Water depletion amounting to about 25% of the total has also had similar effects, particularly by eliminating the backwater nursery areas. A predicted decrease in agricultural use and increase in energy development use would decrease the amount of used irrigation water percolating back into the groundwater and streams. In addition, water allocated...
ABSTRACT: As coal resources are developed in the Northern Great Plains regions, new reservoirs are being considered to meet expanding water demands. The amount of water available for industrial diversion, however, could be limited by regulations that require minimum flow levels to be maintained downstream of the reservoir sites. Computer simulations of potential reservoirs were used to determine to what extent, if any, instream flow requirements might limit the ability of reservoirs to deliver industrial water supplies. Data on instream flow requirements, potential reservoir sites, and historic runoff were input for the simulation of the Powder River Region of Montana and Wyoming. Results of the simulations compared...

The Upper Colorado River Basin contains large deposits of oil shale, tar sands, crude oil, coal, and natural gas. Agriculture still accounts for 90% of the water depletions, but future development of these energy resources is expected to take increasing amounts of water. A mixed-integer programming model was used to maximize returns to land, water, and mineral resources. The results were used to assess the need for government-sponsored water conservation measures to supplement water saving techniques employed by the private sectors in response to increased water prices. The feasibilities of various water saving techniques by industries and of various government-sponsored water conservation measures were examined...
This integrated study examines the implications of changes in crop water demand and water availability for the reliability of irrigation, taking into account changes in competing municipal and industrial demands, and explores the effectiveness of adaptation options in maintaining reliability. It reports on methods of linking climate change scenarios with hydrologic, agricultural, and planning models to study water availability for agriculture under changing climate conditions, to estimate changes in ecosystem services, and to evaluate adaptation strategies for the water resources and agriculture sectors. The models are applied to major agricultural regions in Argentina, Brazil, China, Hungary, Romania, and the US,...
Construction of major dam projects in the Western States requires a re-examination of Indian water rights. Roughly analogous to the nineteenth century problem of Indian land rights, the twentieth century issue of Indian water rights has shifted from water ownership to its best use. Conflicts exist between the western water law of prior appropriation and the Indian rights to the water. The United States Supreme Court addressed the issue in Winters v. United States by holding that the Indian rights controlled over state law. However, the standard for measuring the quantity of water reserved to the Indians was not determined, subsequently causing much conflict. Although the Winters doctrine grants rights to the American...

Most southwestern cities were founded along rivers or in areas having springs or readily available ground water. Because of the generally sparse precipitation, the renewable fresh water supply in the Southwest is smaller than most other areas of the United States. Despite the arid climate, water use has increased rapidly, first in the form of irrigation, and more recently the use in cities. This has caused extensive development of local water resources and overdraft of ground water basins in some areas. It is difficult to implement new local supplies and importation projects due to a myriad of environmental and legal constraints and a general shortage of public funds. Various opportunities and plans for water management,...

Profound changes are now occurring in the Colorado River Basin. New societal demands for water are on a collision course with vested legal rights and past commitments. The exploitation of fossil fuels in the area poses great problems for the traditional paramount concerns of reclamation and agriculture. The ' law of the river ' is actually a composite of many statutes, compacts, court decisions, contracts, regulations and administrative rulings. Generally speaking, the flow of the Colorado River is divided among users on the basis of beneficial consumptive use. The allocation system operates at four levels: international, interregional, interstate, and intrastate. Legal problems on the river are partially the function...
