Current (2004-07) conditions and changes in ground-water levels from predevelopment to 2007, Southern High Plains aquifer, east-central New Mexico: Curry County, Portales, and Causey Lingo underground water basins Current (2004-07) conditions and changes in ground-water levels from predevelopment to 2007, Southern High Plains aquifer, east-central New Mexico: Curry County, Portales, and Causey Lingo underground water basins
The Southern High Plains aquifer is the principal aquifer in Curry and Roosevelt Counties, N. Mex., and primary source of water in southeastern New Mexico. Successful water-supply planning for New Mexico's Southern High Plains requires knowledge of the current aquifer conditions and a context to estimate future trends given current aquifer-management policy. This report provides a...
Current (2004-07) conditions and changes in ground-water levels from predevelopment to 2007, Southern High Plains aquifer, southeast New Mexico: Lea County underground water basin Current (2004-07) conditions and changes in ground-water levels from predevelopment to 2007, Southern High Plains aquifer, southeast New Mexico: Lea County underground water basin
The Southern High Plains aquifer is the principal aquifer and primary source of water in southeastern New Mexico. The Lea County portion of the aquifer covers approximately the northern two thirds of the 4,393-square-mile county. Successful water-supply planning for New Mexico's Southern High Plains requires knowledge of the current aquifer conditions and a context from which to estimate...
Differences in Reservoir Bathymetry, Area, and Capacity Between December 20-22, 2005, and June 16-19, 2008, for Lower Taum Sauk Reservoir, Reynolds County, Missouri Differences in Reservoir Bathymetry, Area, and Capacity Between December 20-22, 2005, and June 16-19, 2008, for Lower Taum Sauk Reservoir, Reynolds County, Missouri
On December 14, 2005, the embankment of the upper reservoir at the Taum Sauk pump storage facility, Reynolds County, Missouri, catastrophically failed and flooded the East Fork Black River, depositing debris and sediment in Johnson's Shut-Ins State Park, the lower Taum Sauk Reservoir, and downstream in the Black River (location map). A bathymetric survey conducted December 20-22, 2005...
Bathymetric contour maps for lakes surveyed in Iowa in 2006 Bathymetric contour maps for lakes surveyed in Iowa in 2006
The U.S. Geological Survey, in cooperation with the Iowa Department of Natural Resources, conducted bathymetric surveys on two lakes in Iowa during 2006 (Little Storm Lake and Silver Lake). The surveys were conducted to provide the Iowa Department of Natural Resources with information for the development of total maximum daily load limits, particularly for estimating sediment load and...
Gulf of Mexico region — Highlighting low-lying areas derived from USGS Digital Elevation Data Gulf of Mexico region — Highlighting low-lying areas derived from USGS Digital Elevation Data
In support of U.S. Geological Survey (USGS) disaster preparedness efforts, this map depicts a color shaded relief representation of the area surrounding the Gulf of Mexico. The first 30 feet of relief above mean sea level are displayed as brightly colored 5-foot elevation bands, which highlight low-elevation areas at a coarse spatial resolution. Standard USGS National Elevation Dataset...
State of Florida 1:24,000- and 1:100,000-scale quadrangle index map - Highlighting low-lying areas derived from USGS Digital Elevation Models State of Florida 1:24,000- and 1:100,000-scale quadrangle index map - Highlighting low-lying areas derived from USGS Digital Elevation Models
In support of U.S. Geological Survey (USGS) disaster preparedness efforts, this map depicts 1:24,000- and 1:100,000-scale quadrangle footprints over a color shaded relief representation of the State of Florida. The first 30 feet of relief above mean sea level are displayed as brightly colored 5-foot elevation bands, which highlight low-elevation areas at a coarse spatial resolution...
