National water summary on wetland resources

This National Water Summary on Wetland Resources documents wetland resources in the United States. It presents an overview of the status of knowledge of wetlands at the present time-what they are, where they are found, why they are important, and the controversies surrounding them, with an emphasis on their hydrology. Wetland resources in each State, the District of Columbia (combined with Maryland), Puerto Rico, the U.S. Virgin Islands, and the western Pacific Islands are described.

Summary of water resources of Salt Lake County, Utah

This report is a summary of a comprehensive report on the present water resources of Salt Lake County, Utah, and the potential for additional development The average total annual withdrawals from surface and underground sources during 1964-68 were about 580,000 acre-feet for all uses that deplete the supply, except that used for maintenance of waterfowl-management areas. The withdrawals projected for the year 2020 are 1,200,000 acre-feet. The maximum annual firm supply that can be derived from the sources now available is about 700,000 acre-feet, of which about 200,000 acre-feet would be derived from subsurface sources. Achievement of this annual yield would require nearly complete regulation of streamflow that now is practically unregulated, larger drawdowns of ground-water levels than have been experienced, and overall management of surface and subsurface sources as parts of a single resource.

Ground-water resources of the Mattapoisett River aquifer, Plymouth County, Massachusetts: Summary for water-resource managers

Proposed increases in municipal pumpage in the Mattapoisett River valley will triple ground-water withdrawals in the next two decades. Because of State and local concern about the long-term effects of these withdrawals on ground-water levels and streamflow, a digital ground-water-flow model was developed to assist water-resource management. Ten development scenarios representing existing and proposed withdrawals were simulated using drought conditions. Under conditions simulating 1965, the driest year of record, predicted water levels in the aquifer are as much as 9 feet lower than average. Under severely dry conditions, simulating only enough recharge to keep the river flowing with no pumping, the predicted water levels are as much as 19 feet lower than average. During the greatest pumping demands, the predicted drawdown in five wells could cause well failure. Simulated pumping demands in six scenarios use all available ground-water discharge. Under severely dry conditions, it is predicted that the downstream half of the river will stop flowing under most pumping plans. (USGS)

Summary of water resources for the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and vicinity, San Diego County, California

Since 1945, precipitation and runoff in California on the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and surrounding areas generally have been below normal, and ground-water levels are declining. Most of the water is of excellent quality. The analysis of water from one well on the Campo Reservation indicates a concentration of nitrate that exceeds the recommended limit established in 1972 by the U.S. Environmental Protection Agency. Most wells and springs in the study area yield water for domestic purposes. The yields range from less than 1 gallon per minute to 210 gallons per minute. Most of the water is produced from shallow aluvial-filled channels or from consolidated rocks that are deeply weathered locally or highly fractured. The well data show that insufficient water is available on the four reservations for large-scale irrigation. (Woodard-USGS)

Statistical and descriptive summaries of water-resources data for the Cannonball River basin, North Dakota and South Dakota

Existing hydrologic data and information for the Cannonball River Basin were compiled by the U.S. Geological Survey in cooperation with the Bureau of Reclamation. This report presents a summary of surface-water quality and streamflow data, ground-water quality data, ground-water level data, water-use data, and other information compiled from the U.S. Geological Survey, Bureau of Reclamation, North Dakota Game and Fish Department, North Dakota Department of Health, North Dakota Parks and Recreation Department, North Dakota State Water Commission, and Standing Rock Sioux Tribe data bases. The data are summarized statistically or descriptively, depending on the amount or nature of the data.
