Water quality of alluvial aquifers, Carroll and Guthrie counties, Iowa, with emphasis on the occurrence of nitrate and pesticides, 1986-87
Samples collected from wells in Carroll and Guthrie Counties, Iowa, were analyzed to describe the chemical quality of the ground water in shallow aquifers. The study began in June 1986 with the selection of 20 shallow wells in Carroll County and 22 shallow wells in Guthrie County. These wells were sampled in the summer and fall of 1986 and 1987. Samples from the wells were analyzed for major ions,

Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams
An automatic system was designed to concurrently measure stage and discharge for the purpose of developing stage-discharge ratings and high flow hydrographs on small streams. Stage, or gage height, is recorded by an analog-to-digital recorder and discharge is determined by the constant-rate tracer-dilution method The system measures flow above a base stage set by the user. To test the effectivenes

National water summary 1987: Hydrologic events and water supply and use
Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the remainder of the withdrawals (72.7 percent) was return f

Delineation of flooding within the Ozark National Scenic Riverways in southeastern Missouri - Round Spring and Powder Mill
This is the second report in a series of U.S. Geological Survey Hydrologic Investigations Atlases to further supplement the National Park Service general management and development concept plan for the Ozark National Scenic Riverways (National Park Service, 1981) in southeastern Missouri (fig. 1). The technical basis on which the National Park Service can develop flood-management plans for use in

Water resources of northeast Iowa
In 1965 a cooperative investigation with the U.S. Geological Survey produced Water Atlas No. 1 (Twenter and Coble, 1965). It presented information on the occurrence, availability, use, quality, and future demand of water in 10 counties in the central part of the state. Subsequent investigations produced Water Atlases No. 4 (Coble and Roberts, 1971) for southeast Iowa, No. 5 (Cagle and Heinitz, 1

U.S. Geological Survey second national symposium on Water quality; abstracts of the technical sessions, Orlando, Florida, November 12-17, 1989
The U.S Geological Survey (USGS) compiled and analyzed existing hydrologic and water-quality data from over 200 stream and estuary stations of the Abemarle-Pamlico estuarine system (A/P) to identify long-term temporal and spatial trends. The dataset included seven stations of the USGS National Stream Quality Accounting Network, two stations of the National Atmospheric Precipitation Deposition moni
Ground-water-quality-monitoring program in Iowa: Nitrate and pesticides in shallow aquifers
Concern exists about the occurrence of agricultural chemicals, primarily nitrate and pesticides, in shallow ground water. In response to this concern, the focus of the Iowa ground-water-quality-monitoring program has shifted to emphasize nonpoint contaminants. The program, which began in 1982, is operated by the U.S. Geological Survey in cooperation with the University of Iowa Hygienic Laboratory

Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1988
Hydrologic data was collected during the 1988 water year in cooperation with the Iowa Department of Natural Resources Geological Survey Bureau in the Big Spring ground-water basin located in Clayton County, Iowa. Information on precipitation, streams, and ground water was collected in the basin.
Total rainfall at Big Spring was 24.08 inches. The greatest monthly rainfall was in September. Calcium

Surface-water quality of the Cedar River basin, Iowa-Minnesota, with emphasis on the occurrence and transport of herbicides, May 1984 through November 1985
The surface-water quality in the Cedar River basin was evaluated by analyzing the occurrence, distribution, and transport of common inorganic constituents and selected trace inorganic and organic constituents, with emphasis on herbicides. The surface-water quality of the Cedar River basin was monitored from May 1984 through November 1985. Depth integrated surface-water samples generally were colle
