Method of estimating natural recharge to the Edwards Aquifer in the San Antonio area, Texas
The method of estimating annual recharge is based on data collected from a network of stream-gaging stations and on assumptions related to applying the runoff characteristics from gaged areas to ungaged areas. The basic approach is a water-balance equation, in which recharge within a stream basin is the difference between measured streamflow above and below the infiltration area of the aquifer plu

Water quality in the Sugar Creek basin, Bloomington and Normal, Illinois
Sugar Creek, within the twin cities of Bloomington and Normal, Illinois, has differences in water quantity and quality as a result of urban runoff and overflows from combined sewers.Water-quality data from five primary and eight secondary locations showed three basic types of responses to climatic and hydrologic stresses. Stream temperatures and concentrations of dissolved oxygen, ammonia nitrogen

A preliminary appraisal of the impact of agriculture on ground-water availability in southwest Georgia
Irrigated acreage in the study area in southwest Georgia increased from 130,000 acres in 1976 to 261,000 in 1977. Acreage irrigated entirely by ground water increased 85 percent for the same period. The largest quantity of ground water used for irrigation was in the Dougherty Plain district, where 92 percent of supplemental irrigation water comes from wells. In the Tifton Upland district, ground w

Physiography and surficial geology of the copper-nickel study region, northeastern Minnesota
The Copper-Nickel study region lies in the Superior Upland physiographic province and is located approximately 60 miles north of Duluth and 100 miles southeast of International Falls, Minnesota. It straddles the Laurentian Divide, which separates Hudson Bay and Lake Superior drainage. The topography exhibits a southwesterly trending lineation that parallels the strike of southeastward-dipping bedr

Hydrology of the Nevin Wetland near Madison, Wisconsin
The 120-acre Nevin wetland at the south edge of Madison, Wis., is a discharge area of the local ground-water system. A hydrologic unit composed of drift and the upper part of an underlying sandstone sequence provides ground-water inflow. Ground water enters as springflow and as leakage upward through the organic wetland soils.
The average annual water budget for the wetland was based on the 3 year

Public water supplies of North Carolina: A summary of water sources, use, treatment, and capacity of water-supply systems
A study of the public water-supply systems in North Carolina with 500 or more customers provides information needed to aid the planning, development, and utilization of the public water supplies of the State. Water use, sources of water, water quality, water treatment and capacity of 224 public-water-supply systems were investigated during 1970-76, and the findings of the investigation, which were

Evaluation of thermograph data for California streams
Statistical analysis of water-temperature data from California streams indicates that, for most purposes, long-term operation of thermographs (automatic water-temperature recording instruments) does not provide a more useful record than either short-term operation of such instruments or periodic measurements. Harmonic analyses were made of thermograph records 5 to 14 years in length from 82 statio

Effects of urban development on the flood-flow characteristics of the Walnut Creek Basin, Des Moines Metropolitan area, Iowa
This report deals with the probable impact of urban development on the magnitude and frequency of flooding in the lower reach of the Walnut creek Basin.Stream-modeling techniques, which include complete definition of unit hydroqraphs and precipitation loss-rate criteria, were utilized to evaluate the effects of urban development as measured by percentages of impervious area over the basin. A mathe

Interim report on streamflow, sediment discharge, and water quality in the Calabazas Creek Basin, Santa Clara County, California
Streamflow, sediment-discharge, and water-quality data are being collected in the Calabazas Creek basin, Santa Clara County, Calif., to determine annual water and sediment discharge at base-line conditions that are representative of a basin prior to urbanization. Results of the first 3 years of the study (1973-75) are given in this report. Climatic conditions during this period were representative

Low-flow characteristics of streams in the Rock-Fox River basin, Wisconsin
Low-flow characteristics of streams in the Rock-Fox River basin, Wis., include estimates of low-flow frequency ad flow duration at 13 gaging stations; low-flow frequency characteristics at 32 low-flow partial-record stations and 78 miscellaneous sites; and a list of base-flow discharge measurements at 244 miscellaneous sites. Equations are provided to estimate low-flow characteristics at ungaged s

Sediment discharge from highway construction near Port Carbon, Pennsylvania
The effects of highway construction on suspended-sediment loads were studied in the upper reaches of the Schuylkill River basin, Schuylkill County, Pennsylvania, from April 1975 to March 1977. From March 1975 to October 1976, 4.3 miles of State Route 209 was relocated through the upper reaches of the basin, a mountainous watershed with a drainage area of 27.1 square miles.

Chemical analyses of surface water in Illinois, 1958–74—Volume I, Des Plaines River basin and Lake Michigan
Samples of surface water were collected and analyzed by the Illinois Environmental Protection Agency and its predecessor, the Stream Pollution Control Bureau of the Illinois Department of Public Health. The results for the period 1958 to 1974 are presented in tabular form and the history of sampling and analytical methods are summarized. Stream discharge data from records of the U.S. Geological Su
