National water summary 1990-91: Hydrologic events and stream water quality National water summary 1990-91: Hydrologic events and stream water quality

National Water Summary 1990-91 Hydrologic Events and Stream Water Quality was planned to complement existing Federal-State water-quality reporting to the U.S. Congress that is required by the Clean Water Act of 1972. This act, formally known as the Federal Water Pollution Control Act Amendments of 1972 (Public Law 92-500), and its amendments in 1977,1979,1980,1981,1983, and 1987, is the...

Habitat suitability index model for brook trout in streams of the Southern Blue Ridge Province: Surrogate variables, model evaluation, and suggested improvements Habitat suitability index model for brook trout in streams of the Southern Blue Ridge Province: Surrogate variables, model evaluation, and suggested improvements

Data from several sources were collated and analyzed by correlation, regression, and principal components analysis to define surrrogate variables for use in the brook trout (Salvelinus fontinalis) habitat suitability index (HSI) model, and to evaluate the applicability of the model for assessing habitat in high elevation streams of the southern Blue Ridge Province (SBRP). In all data...

Approximate altitude of water levels in wells completed in the Chicot and Evangeline aquifers in the Houston area, Texas, January-February 1991 Approximate altitude of water levels in wells completed in the Chicot and Evangeline aquifers in the Houston area, Texas, January-February 1991

This report is one in a series of reports that annually depict altitudes of water levels since 1977, the most recent of which (Barbie and others, 1991) presented maps of the altitudes of water levels for 1990. This report was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, and preents approximate altitudes of water levels in wells in...

Hydrology of two tidal marshes in North Carolina where open-marsh water management modifications have been implemented Hydrology of two tidal marshes in North Carolina where open-marsh water management modifications have been implemented

In 1988 and 1989, open-marsh water management modifications were implemented at tidal marshes near West Onslow Beach and Hobucken, North Carolina, as part of a pilot program to evaluate the effectiveness of ditching techniques as a mosquito-control method in open marshes. In 1984, before implementation of the modifications, a study was initiated to allow definition of the effects of...

Agricultural chemical interchange between ground water and surface water, Cedar River basin, Iowa and Minnesota: A study description Agricultural chemical interchange between ground water and surface water, Cedar River basin, Iowa and Minnesota: A study description

A review of the data collected in the Cedar River basin, Iowa and Minnesota, indicates that atrazine is consistently detected in the main-stem river at concentrations greater than 0.10 microgram per liter even during periods of extended base flow. The primary source of atrazine in the river during these periods of base flow is not known. This study is designed to determine how atrazine...

Surface- and ground-water quality data at selected landfill sites in Mecklenburg County, North Carolina, 1979-92 Surface- and ground-water quality data at selected landfill sites in Mecklenburg County, North Carolina, 1979-92

The U.S. Geological Survey initiated an urban water-quality study in 1979 in cooperation with the City of Charlotte and Mecklenburg County, North Carolina. As part of this study, a water-quality monitoring network was established at selected landfill sites in Mecklenburg County. Water-quality samples were collected at 27 surface-water sites and 97 ground-water sites at 5 landfills from...

U.S. Geological Survey; North Carolina's water resources; a partnership with State, Federal and local agencies U.S. Geological Survey; North Carolina's water resources; a partnership with State, Federal and local agencies

For more than 80 years, the Federal-State Cooperative Program in North Carolina has been an effective partnership that provides timely water information for all levels of government. The cooperative program has raised awareness of State and local water problems and issues and has enhanced transfer and exchange of scientific information. The U.S. Geological Survey (USGS) conducts...
