Aquatic Biology in Nederlo Creek, Southwestern Wisconsin

Description: From abstract: This report presents the results of biologic investigations by the U.S. Geological Survey and the Wisconsin Department of Natural Resources during a study of hydrology and water quality in a small drainage basin in the "Driftless Area" of southwest Wisconsin. The investigation included aquatic macrophytes, periphytic and planktonic algae, benthic invertebrates, and trout population dynamics during 1967-78.

Aquifer Test Results, Green Swamp Area, Florida

Description: From abstract: "An aquifer test conducted in the Green Swamp area December 15-16, 1975 was designed to stress the uppermost part of the Flordian aquifer so that the leakage characteristics of the overlying confining bed could determined." This report includes those results.

Areal Extent of a Plume of Mineralized Water from a Flowing Artesian Well in Dade County, Florida

Description: Abstract: A flowing artesian well tapping the Floridan aquifer at Chekika Hammock State Park, Dade County, Florida, has been contaminating the overlying Biscayne aquifer with saline water since 1944. The contaminating plume extends approximately 7 miles downstream and southeast of the well and ranges in width from 1 to 2 miles. The area of contamination is approximately 12 square miles. The primary contaminating chemical constituents are chloride, sodium, and sulfate ions.

Base Flow of Streams on Long Island, New York

Description: Purpose and scope: The purpose of this report is to quantify the base flow of 19 continuously gaged Long Island streams during 1960-75, which includes the 1962-66 drought. These base-flow data will be used in calibrating computer models designed to predict the response of Long Island streams to hydrologic stresses such as the lowering of ground-water levels in response to large-scale sanitary sewering. The data will also be used to assess the long-term impact expected to result from storm- and … more

The Benchmark Farm Program - A Method for Estimating Irrigation Water Use in Southwest Florida

Description: From introduction: The purpose of this report is to present irrigation water-use data for selected farms and to show how these data are used to estimate total water use for irrigating various crops in southwest Florida. The study area includes all of the Southwest Florida Water Management District and is about 10,000 miles in size (figure 1). The initial emphasis on benchmark farm locations was in Hillsborough, Manatee, and Polk Counties. As the program continues, new farms are being added in s… more

Characteristics of Urban Runoff from Grange Hall Creek at Northglenn, Adams County, Colorado

Description: Purpose: The purpose of the study was to (1) determine quantity and quality of urban runoff from the upper Grange Hall Creek drainage basin in Northglenn; (2) identify constituents exceeding water-quality standards for agricultural waters; (3) compare differences in quality between dry-weather flow, snowmelt runoff and rainfall runoff; (4) determine rainfall-runoff relationships; (5) investigate relationships between constituent concentrations, specific conductance, and streamflow; and (6) sugg… more

Chloride Concentration in Water from the Upper Permeable Zone of the Tertiary Limestone Aquifer System, Southeastern United States

Description: From introduction: This report is one of a series of preliminary products depicting the hydrogeologic framework, water chemistry, and hydrology of the aquifer system. The map shows the distribution of chloride ions in water from the upper permeable zone of the limestone aquifer system. The upper permeable zone consists of several formations, primarily in Tampa, Suwannee, Ocala, and Avon Park Limestones.

A Data-Management System for Areal Interpretive Data for the High Plains in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

Description: From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

A Digital-Computer Model of the Big Sioux Aquifer in Minnehaha County, South Dakota

Description: From purpose and approach of study: The purpose of this study was to develop a predictive model of the ground-water system for use as a management tool. The model will be used by State and local officials in evaluating the effects of alternative methods of controlling or developing the ground-water resources of the Big Sioux aquifer in Minnehaha County.

Digital Model of Predevelopment Flow in the Tertiary Limestone (Floridian) Aquifer System in West-Central Florida

Description: From introduction: This study is part of a regional study of the Tertiary limestone aquifer system in the southeastern United States. The regional study encompasses all of Florida and extends into Georgia, Alabama, and South Carolina--a total area of about 82,000 square miles.

Digital-Transport Model Study of the Potential Effects of Coal-Resource Development on the Ground-Water System in the Yampa River Basin, Moffat and Routt Counties, Colorado

Description: From abstract: Large increases in coal mining currently (1979) taking place in the Yampa River basin are expected to continue during the 1980's and may adversely impact both the ground-water and surface-water quality in the basin. One potential source of adverse impact is the dissolution of soluble minerals contained in the overburden material disturbed during the mining. This potential impact was investigated using digital ground-water transport-modeling techniques.

Effects of a Floodwater-Retarding Structure on the Hydrology and Ecology of Trout Creek in Southwestern Wisconsin

Description: Abstract: The primary effect of a floodwater-retarding structure (FRS) on the flow of Trout Creek, Wisconsin, is attenuation of flood peaks. Reduction of flood peaks ranged from 58 to 91 percent during the study period, 1975 to 1979. An inverse relationship exists between sediment concentration and outflow from the FRS during floods. Most sediment stored in the flood pool during floods is released from the reservoir during subsequent reduced discharge. Sediment-trapping efficiency of the FRS wa… more

The Effects of Channel Excavation on Water-Quality Characteristics of the Black River and on Ground-Water Levels Near Dunn, North Carolina

Description: From abstract: Data were collected at three sites on the Black River near Dunn, North Carolina, to define the effects of channel excavation on water-quality characteristics and on ground-water levels in nearby areas. Background data were collected at a site upstream from the 5-mile-long excavated reach. Changes in hydrologic characteristics were determined from data collected before, during, and after the construction period 1976-81. Significant changes occurred in shallow ground-water levels, … more

Estimated Natural Streamflow in the Rio San Jose Upstream from the Pueblos of Acoma and Laguna, New Mexico

Description: From purpose and scope: The purpose of this study was to estimate the natural streamflow in the Rio San Jose at the upstream boundaries of the Pueblos of Acoma and Laguna. Natural streamflow is defined for this study as the streamflow that would have occurred if water development in the basin upstream from the pueblos had never taken place.

Evaluation of Rainfall-Runoff Data Network, Rockland County, New York

Description: Purpose and scope: This report evaluates the rainfall-runoff data collected at 12 sites on 10 streams in Rockland County during 1975-79 and examines the adequacy of the rainfall-runoff models developed for 10 of the sites. The predictive capability of the models will dictate their use in eventual determinations of flood-frequency relationships at each gaged site.
