Shallow ground-water flow, water levels, and quality of water, 1980-84, Cowles Unit, Indiana Dunes National Lakeshore Shallow ground-water flow, water levels, and quality of water, 1980-84, Cowles Unit, Indiana Dunes National Lakeshore

The Cowles Unit of Indiana Dunes National Lakeshore in Porter County, northwest Indiana, contains a broad dune-beach complex along the southern shoreline of Lake Michigan and a large wetland, called the Great Marsh, that occupies the lowland between the shoreline dunes and an older dune-beach complex farther inland. These lacustrine sediments form a surficial aquifer that extends from...

Method for estimating low-flow characteristics of ungaged streams in Indiana Method for estimating low-flow characteristics of ungaged streams in Indiana

Equations for estimating the 7-day, 2-year and 7-day, 10-year low flows at sites on ungaged streams are presented. Regression analysis was used to develop equations relating basin characteristics and low-flow characteristics at 82 gaging stations. Significant basin characteristics in the equations are contributing drainage area and flow-duration ratio, which is the 20-percent flow...

Hydrologic data in small watersheds, coal-mining region, west-central Indiana, October 1980 to June 1983, and instrumentation and methods of collecting the data Hydrologic data in small watersheds, coal-mining region, west-central Indiana, October 1980 to June 1983, and instrumentation and methods of collecting the data

Hydrologic data were collected in seven watersheds ranging in area from 0.11 to 4.87 square miles. Principal uses of land include farming in two of the watersheds, farming and forestry in one, farming and unreclaimed surface coal mines in one, reclaimed surface coal mines in two, and an unreclaimed surface coal mine in one. Methods and instrumentation used in collecting samples and...

Hydrologic effects of ground- and surface-water withdrawals in the Howe area, Lagrange County, Indiana Hydrologic effects of ground- and surface-water withdrawals in the Howe area, Lagrange County, Indiana

Geometry and hydraulic characteristics of a 46.5 sq mi area of the sand and gravel outwash-aquifer system between Fawn and Pigeon Rivers in Lagrange County were defined in a study of the effect of current and potential uses of water on the aquifer, streams, lakes, and wetlands. There are three aquifers: Aquifer 1, a surficial water table aquifer that ranges from 10 to 60 ft in thickness...

Pilot projects are being conducted in Colorado and Ohio to determine the extent to which existing water quality data, collected by different groups for various purposes and using different procedures, can be aggregated for use in addressing selected water quality questions of regional and national scope. The project has been divided into three phases; this report presents the results of...

Hydrologic effects of ground- and surface-water withdrawals in the Milford area, Elkhart and Kosciusko counties, Indiana Hydrologic effects of ground- and surface-water withdrawals in the Milford area, Elkhart and Kosciusko counties, Indiana

Agricultural irrigation in northern Indiana has increased rapidly since 1975 and might double by the year 2000. A 16.5 square-mile area in north-central Indiana was studied to determine possible effects of increased irrigation on local water supply. In 1982, an average of 2 inches of water was used to irrigate 975 acres of sandy soil overlying highly transmissive outwash deposits...

Chemical and isotopic characteristics of brines from three oil- and gas-producing sandstones in eastern Ohio, with applications to the geochemical tracing of brine sources Chemical and isotopic characteristics of brines from three oil- and gas-producing sandstones in eastern Ohio, with applications to the geochemical tracing of brine sources

Chemical and isotopic characteristics of selected inorganic constituents are reported for brines from the Berea Sandstone of Mississippian age, the Clinton sandstone, Albion Sandstone of Silurian age, and the Rose Run formation of Cambrian and Ordovician age in 24 counties in eastern Ohio. Ionic concentrations of dissolved constituents in brines from these formations generally fall in...

Determination of reaeration-rate coefficients of the Wabash River, Indiana, by the modified tracer technique Determination of reaeration-rate coefficients of the Wabash River, Indiana, by the modified tracer technique

The modified tracer technique was used to determine reaeration-rate coefficients in the Wabash River in reaches near Lafayette and Terre Haute, Indiana, at streamflows ranging from 2,310 to 7,400 cu ft/sec. Chemically pure (CP grade) ethylene was used as the tracer gas, and rhodamine-WT dye was used as the dispersion-dilution tracer. Reaeration coefficients determined for a 13.5-mi reach...

Chemical and biological quality of streams at the Indiana Dunes National Lakeshore, Indiana, 1978-80 Chemical and biological quality of streams at the Indiana Dunes National Lakeshore, Indiana, 1978-80

A variety of land uses affects water quality of streams at the Indiana Dunes National Lakeshore. Discharge from storm sewers and runoff from roads contributed lead, zinc, and chlorinated hydrocarbons (chlordane, DOT, ODD, DDE, and PCB's) to all streams except Derby ditch. In addition, the Little Calumet River received ammonia from industrial discharges, and organic materials, nitrogen...

Ground-water resources of the White River basin, Randolph County, Indiana Ground-water resources of the White River basin, Randolph County, Indiana

The two major aquifer systems in Randolph County, Indiana are sand and gravel and bedrock (limestone, dolomite, and shale of Silurian to Odovician age). The average thickness of the sands and gravels is 15 ft, and the aquifers are areally discontinuous. The bedrock aquifer underlies the entire study area and is estimated to be 150 ft in thickness. Six pumping plans simulated in the two...

Techniques for estimating magnitude and frequency of floods on streams in Indiana Techniques for estimating magnitude and frequency of floods on streams in Indiana

Equations are presented for estimating the magnitude and frequency of floods at ungaged sites on unregulated and nonurban streams in Indiana. The equations were developed by multiple-regression, analysis of basin characteristics and peak-flow statistical data from 242 gaged locations in Indiana, Ohio, and Illinois. The State of Indiana was divided into seven areas on the basis of the...
