A Method for Estimating Ground-Water Return Flow to the Lower Colorado River in the Yuma Area, Arizona and California--Executive Summary

Description: Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that will permit an accounting of ground-water return flows from each side of the Colorado River in the Yuma reach. The estimates of return flow can be used by water-management agencies in determining return-flow credits for the States of Arizona and California.

Low-Flow Characteristics of Wisconsin Streams at Sewage-Treatment Plants

Description: Abstract: Low-flow characteristics of Wisconsin streams at 415 sewage-treatment plants are presented in this report. The low-flow characteristics presented are the annual minimum 7-day mean flow that occurs on the average of once in 2 years and the annual minimum 7-day mean flow that occurs on the average of once in 10 years. The low-flow characteristics at most sewage-treatment plants were determined by correlating baseflow measurements at the sewage-treatment plants to the concurrent daily mean flow at continuous-record gaging stations in the area. The accuracy determined by the standard error of estimate for the 10-year low flow ranged from 18 percent at continuous-record gaging stations to 70 percent when only three base-flow measurements were available. The standard error of 70 percent is larger than anticipated when the project was initiated. This was the result of extremely poor base-flow conditions during the 2-year data collection period. Additional base-flow conditions will be obtained during subsequent years which will improve the standard error somewhere between 29 and 45 percent.

A Method for Estimating Ground-Water Return Flow to the Lower Colorado River in the Yuma Area, Arizona and California

Description: Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that permits an approximate accounting of ground-water return flow from each side of the Colorado River in Yuma reach. The method presented in this report was developed specifically for application in the Yuma area. The validity of the assumptions inherent in the method was evaluated on the basis of the local hydrologic system. The applicability of the method to other hydrologic systems is not addressed in this report.

Hydrogeologic Features of the Alluvial Deposits in the Owl Creek Valley, Bighorn Basin, Wyoming

Description: Introduction: The alluvial deposits form the principal aquifer in the Owl Creek Valley and the source of water to many stock and domestic wells and to a few irrigation wells. In 1975, the U.S. Geological Survey, in cooperation with the Wyoming State Engineer, began an investigation of the hydrology and geology, including the geomorphology, of Owl Creek Valley (fig. 1) to determine possible favorable areas for obtaining ground water of adequate chemical quality for irrigation and other uses. The part of Owl Creek basin investigated is downstream from Anchor Reservoir and includes North Fork, South Fork, and the mainstem of Owl Creek (pi. 1). However, the area downstream from Embar Ranch (pi. 1) was emphasized during the study.

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.

Hydrologic Effects of Storing Liquified Sewage Sludge on Strip-Mined Land, Fulton County, Illinois

Description: From introduction: In 1971, the U.S. Geological Survey (USGS) began a cooperative study to measure stream discharge, suspended-sediment load, and chemical quality of surface waters draining the project area. In 1976, the study was expanded to include measurement of ground-water levels and quality. The general hydrologic system in the vicinity has been described by Patterson, Fuentes, and Toler (1982).

Evaluation of the Streamflow-Data Program in Pennsylvania

Description: Abstract: The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information requires knowledge of the information in the data base and an assessment of the potential for improving the accuracy of data-transfer mechanisms. The analytical technique known as Network Analysis for Regional Information is used to assess acquired streamflow information and to evaluate its transferability within previously determined regions of homogenous streamflow characteristics. Regression equations that relate low-, mean-, and flood-flow characteristics to basin parameters are the data-transfer mechanisms used in the evaluation. This analysis showed that only minor improvements in the regression equations can be expected after 20 additional years of data collection at gages in the 1980 program. Transfer mechanisms with less model error are needed for improved data transferability. A more efficient program can be achieved by discontinuing selected gages in the planning-and-design network. To this end, 11 continuous-record and 25 partial-record gages were selected to be discontinued by April 1, 1980. Additionally, 6 continuous-record and 29 partial-record gages are suggested to be discontinued at the end of the 1985 water year.

Flood of August 31--September 1, 1978, in Crosswicks Creek Basin and Vicinity, Central New Jersey

Description: From abstract: "A thunderstorm during the evening of August 31 and the morning of September 1, 1978, caused flooding in a small area of South-central New Jersey. Maximum peaks of record occurred on the Upper Crosswicks Creek basin in the vicinity of Fort Dix, Wrightstown, and New Egypt. At New Egypt, high water crest elevations for Crosswicks Creek were approximately four feet higher than the previous maximum recorded on August 28, 1971.

Water Resources of the Myakka River Basin Area, Southwest Florida

Description: Abstract: Ground water in the Myakka River basin area is obtained from a water-table aquifer and from five zones in an artesian aquifer. Wells in the water-table aquifer yield generally less- than 50 gal/min and dissolved solids concentration is less than 500 mg/1 except in coastal areas and the peninsula southwest of the Myakka River estuary. Wells in the Venice area that tap zone. 1 usually yield less than 30 gal/min. The quality of the water is good except in the peninsula area. Zone 2 is the most highly developed aquifer in the heavily populated coastal areas. Wells yield as much as 200 gal/min. In most areas, water is of acceptable quality.Wells that tap zone 3 yield as much as 500 gal/min. Fluoride concentration ranges from 1 to 3.5 mg/1. Zone 4 yields as much as 1,500 gal/min to large diameter wells. Except in the extreme northeastern part of the area water from zone 4 usually contains high concentrations of fluoride and sulfate. Zone 5 is the most productive aquifer in the area, but dissolved solids concentrations usually are too high for public supply except in the extreme northeast.Surface water derived from natural drainage is of good quality except for occasional high color in summer.
