Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains requires information on floods. This report provides information on flood stages and discharges, flood magnitude and frequency, bench mark data, and flood profiles for the Raccoon River and some of its tributaries. It covers the Raccoon River, the North Raccoon River to the northern boundary

The Indiana State Board of Health is developing a State water-quality management plan that includes establishing Limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Little Laughery Creek tributary and Little Laughery Creek was used to predict alternatives for future waste loadings that would be compatible with Indiana stream water-quality st

A required 1,100 gallons of water per minute for irrigating agricultural lands used by the Coast Indian Community on the Resighini Rancheria near Klamath, Califomia, cannot be developed from wells. However, the required quantity of water might be developed from a trench installed in sand and gravel deposits that are hydraulically connected with the Klamath River.

Water-quality data identify surface-water-quality problems in Bear Creek basin, Jackson County, Oreg., where possible, their causes or sources. Irrigation and return-flow data show pastures are sources of fecal coliform and fecal streptococci bacteria and sinks for suspended sediment and nitrite-plus-nitrate nitrogen. Bear Creek and its tributaries have dissolved oxygen and pH values that do not m

A high-intensity summer rain estimated at 8 inches in 2 hours caused flooding on a small stream near Thornville, Ohio, destroying a culvert and highway fill on State Route 188. Computation of peak discharges of 3,250 feet3 per second at a site 4,400 feet above and of 4,050 feet3 per second at a site 3,250 feet below the culvert indicates a greater than 100-year flood.

Generally, the water quality of Indian Creek-Van Buren watershed is suitable as a source of Municipal, industrial and agricultural water supply and for fish and wildlife. This suitability is based upon comparisons of the existing water quality of Indian Creek to Federal and State water quality standards and criteria developed for the protection of water sources and the fish and wildlife that inhab

A series of seven studies of the quality and quantity of low flows in a 35.5-mile reach of the Colorado River upstream from Colorado City, Texas, were made from February 1975 to March 1978 to delineate areas of saline inflow. These studies showed generally that ground water contributed throughout the reach is saline, but that loads of dissolved constituents in ground-water accretions are highest i

Water—quality and suspended—sediment samples were collected in two basins in southwest Georgia to determine whether water—quality problems have resulted from agricultural practices. Samples were collected monthly and during periods of storm runoff from December 1976 through July 1978. Concentrations of chemical constituents relevant to agricultural practices were found to be low, even during perio

The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for liquid wastes discharged into Indiana streams. A digital computer model was used to predict alternatives for future waste loadings on Little Lick and Big Lick Creeks that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic condi

Surficial-sand aquifers in 960 square miles of central Minnesota have been studied to determine the occurrence, availability, and suitability of the surficial aquifer as a source of water. The aquifer is being increasingly developed for irrigation. During the drought of 1976, nearly 24,000 acre-feet of ground water was withdrawn for irrigation, more than double that of the previous year. The numbe

This report was prepared as an aid to developing a better understanding of the groundwater resources of North Carolina. It consists of 46 essays grouped into five parts. The topics covered by these essays range from the most basic aspects of ground-water hydrology to the identification and correction of problems that affect the operation of supply wells. The essays were designed both for self stud

The purpose of this 5-year study is to (1) evaluate the sediment transport, streamflow characteristics, and stream-channel morphology, (2) relate the above to land-use practices; and (3) evaluate the effect that changes in land-use practices will have on Pheasant Branch basin near Middleton, Wis. This report presents findings of sediment transport, streamflow characteristics, and stream-channel mo
