Tropic And East Fork Irrigation Company, Tropic Ditch Replacement Project, Environmental Assessment, Bureau Of Reclamation, Provo Area Office

All U.S. Government Documents (Utah Regional Depository)

The purpose of this project is to reduce the amount of salt entering the Paria River and ultimately the Colorado River. One way to reduce the amount of salt reaching the Colorado River is to eliminate seepage from the historic Tropic Ditch. The Bureau of Reclamation, Provo Area Office has proposed funding for the project under the Colorado River Salinity Control Program. In addition to reducing the amount of salt loading, the project would also conserve water lost to evaporation and seepage.

The purpose of this Environmental Assessment (EA) is to analyze the potential environmental consequences of the proposed construction …

Record Of Decision: Operation Of Flaming Gorge Dam Final Environmental Impact Statement, U.S. Bureau Of Reclamation

All U.S. Government Documents (Utah Regional Depository)

The Bureau of Reclamation (Reclamation) has completed a final environmental impact statement (EIS) on the operation of Flaming Gorge Dam. The EIS describes the potential effects of modifying the operation of Flaming Gorge Dam to assist in the recovery of four endangered fish, and their critical habitat, downstream from the dam. The four endangered fish species are Colorado pikeminnow (Ptychocheilus lucius), humpback chub (Gila cypha), razorback sucker (Xyrauchen texanus), and bonytail (Gila elegans). Reclamation would implement the proposed action by modifying the operations of Flaming Gorge Dam, to the extent possible, to achieve the flows and temperatures recommended by participants …

Proposed Experimental Actions For Water Years 2005-2006 Colorado River, Arizona, In Glen Canyon National Recreation Area And Grand Canyon National Park, U.S. Department Of The Interior, Bureau Of Reclamation, National Park Service, U.S. Geological Survey

All U.S. Government Documents (Utah Regional Depository)

In September 2002 the Bureau of Reclamation, National Park Service (NPS), and U.S. Geological Survey released an environmental assessment (EA) on proposed experimental releases from Glen Canyon Dam and removal of non‐native fish from the Colorado River in Grand Canyon, Arizona (Bureau of Reclamation, NPS, and USGS 2002). The experiment was developed by the Grand Canyon Monitoring and Research Center of the U.S. Geological Survey (GCMRC), cooperating scientists, and the Technical Work Group (TWG) of the Glen Canyon Dam Adaptive Management Program (GCDAMP). It was recommended to the Secretary of the Interior by the Adaptive Management Work Group (AMWG), a …

Water Resources Management Plan Arches National Park And Canyonlands National Park, United States Department Of The Interior National Park Service

All U.S. Government Documents (Utah Regional Depository)

This Water Resources Management Plan describes the water resources of Arches and Canyonlands National Parks and the issues affecting them. This plan provides detailed descriptions of the hydrologic environment in both parks, discussion of management issues developed in two scoping sessions, and management directives in the form of project statements. Typically, a Water Resources Management Plan is preceded by a scoping meeting held at the park. In this case, the Southeast Utah Group of parks (Southeast Utah Group), which includes Arches National Park, Canyonlands National Park, and Natural Bridges National Monument, held two scoping meetings. The first scoping session, held …

Open Stream Collection And Diversion: An Added Dimension In Providing Water For Grazing Animals, United States Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

This technical note describes an effective system for collecting water from open streams and conveying it several miles via pipeline systems to watering troughs in arid locations. Perhaps one of the greatest challenges in managing lands that produce forage for grazing animals is to strike a desirable balance between forage and water. However, on native grazing lands, this is rarely the case due to terrain and uneven distribution of water. The "open stream collection and diversion system" addresses this issue with a specific engineering solution.

The CRWQIP/CRSC programs provide for projects upstream of Imperial Dam (near Yuma, Arizona, on the Arizona-California border) that are necessary …

Water Conservation Through Irrigation Technology, Donald H. Negri, John J. Hanchar, United States Department Of Agriculture, Economic Research Service

All U.S. Government Documents (Utah Regional Depository)

Improved irrigation technology and advanced farm management practices offer an opportunity for agriculture to use water more efficiently. Farmers may install new equipment, such as drip irrigation systems, or adopt advanced water management practices to conserve water without sacrificing crop yields. While farmers' decision to adopt water-saving irrigation technology responds to the cost of water, physical properties of the land such as topography or soil properties of the land such as topography or soil texture dominate the choice of irrigation technology.

An Analysis Of The Water Situation In The United States: 1989-2040, Richard W. Guldin, Usda Forest Service

All U.S. Government Documents (Utah Regional Depository)

Several Federal agencies have historically had responsibilities for conducting assessments of the Nation's water resources. The U.S. Geological Survey (USGS), U.S. Army Corps of Engineers, U.S. Department of Agriculture's Soil Conservation Service (SCS), and U.S. Environmental Protection Agency (EPA) and its predecessor agencies, among others, have conducted studies assessing the current situation and future prospects for water in particular regions of the country. Responsibility for national water assessments was assigned to the U.S. Water Resources Council (WRC) by the Water Resources Planning Act of 1965. With the demise of the WRC in 1981, several member agencies have attempted to take …

Assessment Of The Radiological Impact Of The Inactive Uranium-Mill Tailings At Mexican Hat, Utah, F. F. Haywood, W. A. Goldsmith, B. S. Ellis, H. M. Hubbard Jr., W. F. Fox, W. H. Shinpaugh, Oak Ridge National Laboratory

All U.S. Government Documents (Utah Regional Depository)

High surface soil concentrations of 226Ra and high above-ground measurements of gamma-ray intensity in the vicinity of the inactive uranium-mill tailings at Mexican Hat show both wind and water erosion of the tailings. The former mill area, occupied by a trade school at the time of this survey, shows a comparatively high level of contamination, probably from unprocessed ore on the surface of the ore storage area near the location of the former mill buildings. However, the estimated health effect of exposure to gamma rays during a 2000-hr work year in the area represents an increase of 0.1% in the …
