Preliminary assessment of the effects of selenium in agricultural drainage on fish in the San Joaquin Valley Preliminary assessment of the effects of selenium in agricultural drainage on fish in the San Joaquin Valley
Concentrations of total selenium were measured in whole-body samples of seven fishes from the Sacramento and San Joaquin River systems and the San Francisco Bay complex. Concentrations of selenium (up to 11 µg/g dry weight in whole-body composite samples) were highest in fish from canals and sloughs in the Grassland Water District (Grasslands) that received large inflows of subsurface...

Distribution patterns of individually identifiable West Indian manatees (Trichechus manatus) in Florida Distribution patterns of individually identifiable West Indian manatees (Trichechus manatus) in Florida
Photographs of distinctively scarred manatees (Trichechus manatus) were taken at aggregation sites throughout Florida and assembled into a catalog for identifying individuals. Resightings of known manatees in different years or at different locations enabled us to document site fidelity and long-distance movements. Of the 891 individuals included in the catalog as of August 1986, 470 (53...

Withdrawals from the Edwards-Trinity aquifer system and contiguous hydraulically connected units, west-central Texas, December 1974 through March 1977 Withdrawals from the Edwards-Trinity aquifer system and contiguous hydraulically connected units, west-central Texas, December 1974 through March 1977
The Edwards-Trinity aquifer system and contiguous hydraulically connected units (fig. 1) are being studied as a part of the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) program. The aquifer system, which underlies about 40,000 mi2 in west-central Texas, comprises mostly near-surface carbonate rocks, sand, and sandstone of Early Cretaceous age (Bush, 1986). Most...

Work plan for regional reconnaissance for selected herbicides and nitrate in ground water of the mid-continent United States, 1991 Work plan for regional reconnaissance for selected herbicides and nitrate in ground water of the mid-continent United States, 1991
An approach was developed to obtain a consistent, regional distribution of herbicide and nitrate data from near-surface aquifers in the corn and soybean producing region of the mid-continent. Near-surface aquifers are defined as those with the top of aquifer material within 50 feet of land surface, regardless of whether the material is saturated or unsaturated. Three hundred wells will...

Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, January-February 1990 Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, January-February 1990
This report is one in a series of reports that depict altitudes of water levels since 1977, the most recent of which (Barbie and other, 1989) presented maps of the altitudes of water levels for 1989. This report was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, and presents approximate altitudes of water levels in wells in the...

Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-91 and 1990-91, and measured compaction, 1973-90, in the Houston-Galveston region, Texas Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-91 and 1990-91, and measured compaction, 1973-90, in the Houston-Galveston region, Texas
This report is one in a series of reports that depict water-level changes and compaction of subsurface material in the Houston-Galveston region. The maps present approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-91 and 1990-91 (figs. 1-4). The location of borehole extensometers is shown in figure 5, and graphs present measured compation for 1973-90 (fig...

Records of wells, drillers' logs, water-level measurements, and chemical analyses of ground water in Chambers, Liberty, and Montgomery Counties, Texas, 1985-89 Records of wells, drillers' logs, water-level measurements, and chemical analyses of ground water in Chambers, Liberty, and Montgomery Counties, Texas, 1985-89
Data for water wells and ground water in Chambers, Liberty, and Montgomery Counties were collected during 1985-89 by the U.S. Geological Survey. This report presents a compilation of records for 4 wells in Chambers County, 8 wells in Liberty County, and 64 wells in Montgomery County. Drillers' logs of 60 wells, water levels for 84 wells, chemical analyses of water for 11 wells, and water...
