The Bureau of Reclamation's Lower Colorado Region serves as the "water master" for the last 688 miles of the Colorado River within the United States on behalf of the Secretary of the Interior. We manage the River and its reservoirs to meet water and power delivery obligations, protect endangered species and native habitat, enhance outdoor recreation opportunities, and provide flood control. The Region also maintains Hoover, Davis and Parker Dams, annually measures and accounts for the water's use, and maintains the river channel and protective levees. The Lower Colorado Region covers an area of nearly 202,000 square miles, and encompasses parts of five states that contribute water to or draw water from...

The Rio Grande provides drinking water for more than six million people, irrigation water for two million acres of land in the United States and Mexico, and supports riparian ecosystems that are home to endangered species like the ocelot and Rio Grande silvery minnow. Climate variability and anthropogenic activities continue to stress this already limited water resource. This project was developed in response to a request from a group of stakeholders who work in the Basin and represent federal, state and local agencies, private industry, farmers, ranchers, and NGOs. These stakeholders identified the need for a comprehensive data resource that spatially depicts where conservation activities are occurring on the ground....

This dataset contains information regarding the acreages of land currently (as of 2004) enrolled in the Conservation Reserve Program (CRP) distributed by county and the year the CRP contract was initiated (1987-2004, excluding 1994 and 1995). Additionally, it contains total acreages of land enrolled in the CRP distributed by county and the contract year (1987-2003). USDA Farm Service Agency's (FSA) Conservation Reserve Program (CRP) is a voluntary program available to agricultural producers to help them safeguard environmentally sensitive land. Producers enrolled in CRP plant long-term, resource-conserving covers to improve the quality of water, control soil erosion, and enhance wildlife habitat. In return, FSA...

The arid Southwest of the United States is confronted with increasing water demands and a limited resource. Past efforts to meet water demand have been directed toward development of scarce water resources. While development programs have been successful in stretching available supply, few feasible development options remain. Furthermore, heavy water utilization has affected water quality within drainage basins. It seems likely that water management will play a much more significant role in water resource allocation in the future. This paper will examine water development activity in the Southwest to date. Attention will be given to several of the problems that have arisen. The paper will then examine water management...
Survey data collected in the San Joaquin Valley of southern California and the Grand Valley of western Colorado reveal that residents of both areas believe that a severe sustained drought is likely to occur within the next 20–25 years and that their communities would be seriously impacted by such an event. Although a severe sustained drought affecting the Colorado River Basin would cause major economic and social disruptions in these and other communities, residents express little support for water management alternatives that would require significant shifts in economic development activities or in water use and allocation patterns. In particular, residents of these areas express little support for strategies...
Water conservation is important for plants that maintain physiologically active foliage during prolonged periods of drought. A variety of mechanisms for water conservation exist including stomatal regulation, foliage loss, above- and below-ground allocation patterns, size of xylem vessels and leaf pubescence. Using the results of a field and simulation study with Artemisia tridentata in the Great Basin, USA, we propose an additional mechanism of water conservation that can be used by plants in arid and semi-arid environments following pulses of water availability. Precipitation redistributed more uniformly in the soil column by roots (hydraulic redistribution of water downward) slows the rate at which this water...

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...

The Colorado Water Conservation Board (CWCB) was created in 1937 for the purpose of aiding in the protection and development of the waters of the state. The agency is responsible for water project planning and finance, stream and lake protection, flood hazard identification and mitigation, weather modification, river restoration, water conservation and drought planning, water information, and water supply protection.

This dataset is a static view of available data from the Pacific Northwest Aquatic Monitoring Partnership (PNAMP) Monitoring Site Manager on 201412. The Monitoring Site Manager describes locations of data collection events for various aquatic monitoring programs in the Pacific Northwest. It includes locations for the US Forest Service Aquatic and Riparian Effectiveness Monitoring Program (AREMP), Bonneville Power Administration’s Columbia Habitat Monitoring Program (CHaMP), Oregon Department of Environmental Quality’s (ODEQ) Ambient Water Quality Monitoring Program, the National Rivers and Streams Assessment (NRSA) in Oregon, the US Forest Service PACFISH/INFISH Biological Opinion Effectiveness Monitoring Program...
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,...
