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

Most ground water used in Geauga County, Ohio, is withdrawn from bedrock aquifers, chiefly sandstones of the Pottsville and Cuyahoga Formations of Pennsylvanian and Mississippian age, respectively. Two potentiometric-surface maps were constructed from water-level measurements of 77 wells and 2 springs made in June and October 1978. The potentiometric surface did not change more than a few feet bet

A glacial aquifer of 70 square miles in the Scioto River valley southeast of Columbus, Ohio, was modeled as a potentially major source of water. The model was constructed from available hydrologic data: Records of precipitation, well hydrographs, well logs, two ground-water level surveys, and analyses of six aquifer tests. Utilizing this array of data, water levels determined from a series of stea

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

This interim report presents preliminary estimating equations developed for the ongoing study, "Flood Frequency of Small Streams in Indiana." The equations were developed by the multiple-regression technique from data collected at 57 crest-stage-gage and 15 rainfall-runoff sites in the study and from 133 streamflow stations in Indiana and 11 in eastern Illinois. Peak discharge was used as the depe

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

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.

Water type in the 241-square mile Porter County watershed in Indiana, was calcium bicarbonate or mixed calcium bicarbonate and calcium sulfate. Concentrations of dissolved chemical constituents in surface water and contents of chlorinated hydrocarbons in streambed samples in the watershed were generally less than water-quality alert limits set by the U.S. Environmental Protection Agency, except in

Chemical and biological water quality in Rattlesnake Creek basin, Ohio, are evaluated. The data include field and laboratory data for eight sites during August 1976- August 1977 and summaries of earlier (1972-76) data. Streamflow was below normal during the study period. Basin waters types were calcium bicarbonate or calcium magnesium bicarbonate. Specific conductance ranged from 405 to 1,300 micr

Twenty-eight Ohio lakes (14 per year) were sampled by the U.S. Geological Survey and Ohio Environmental Protection Agency for the water-quality characteristics during the spring and summer of 1976 and 1977. Data items included: profiles of temperature, dissolved oxygen, pH, and specific conductance; physical, biological, nutrient, and organic characteristics; major and minor constituents; and phys
