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 the Wabash River in Huntington County, Ind., was used to predict alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defin

The Indiana State Board of Health is developing a State water-quality plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Duck Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic conditions, su

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 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.

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

A computer model of the Potomac-Raritan-Magothy aquifer system was used to simulate the effects of supplementing ground water with water from the Delaware River. Replacement of ground water pumpage with surface water in a 150-square-mile area near Camden, N.J., was simulated. Artificial recharge of surface water was also simulated in the same area. A series of nine simulations was made. The simula

From October 1972 through September 1977, the effects of highway construction in the 38 square mile Blockhouse Creek basin were studied. Water discharge, suspended-sediment discharge, and stream-temperature data were collected at four stations in the basin. The 5-year period included 1 year before construction, 2 years during construction, and 2 years after construction. The effects of stream relo

The U.S. Soil Conservation Service needs chemical, biological, microbiological, and hydrological data to prepare an environmental evaluation of the water quality in the Cypress Creek watershed, Warrick County, Ind., before plans can be devised to (1) improve water quality, (2) minimize flooding, (3) reduce sedimentation, and (4) provide adequate outlets for drainage in the watershed. The U.S. Geol

Water-quality data collected in the upper Oyster Creek drainage basin, Ocean County, N.J., indicate that the stream has excellent water quality except for a persistently low pH. The mean concentrations of the major inorganic ions were all less than 6.0 milligrams per liter. Mean concentrations of total nitrogen and total phosphorus were 0.15 mg/L and 0.01 mg/L, respectively. Dissolved oxygen avera

On August 3, 1977, the Surface Mine Control and Reclamation Act, Public Law 95-87 (the Act) was enacted by the 95th Congress. Under Section 507(b)(11) of the Act, an appropriate Federal or State agency must provide applicants for coal-mining permits hydrologic and water-quality information for the general use of proposed mining. To help meet the goals of the Act, the U.S. Geological Survey is desi

The U.S. Geological Survey is making a river-quality assessment of the Schuylkill River basin in Pennsylvania from October 1978 to March 1981. It is part of a continuing program designed to demonstrate the effectiveness of river-quality studies for basin planning and water-resource management. Study objectives include determining (1) presence of selected trace metals and organic substances in the

This report documents rainstorms and resultant floods in central and southern Indiana during the summer of 1979. Major flooding was caused by three storms, one in June and two in July 1979, centered primarily in central and southern Indiana. Peak discharge exceeded the 100-year recurrence interval at 16 sites in this area. State Civil Defense officials estimated that almost 50-million dollars dama
