Hydrologic modification to improve habitat in riverine lakes: Management objectives, experimental approach, and initial conditions
The Finger Lakes habitat-rehabilitation project is intended to improve physical and chemical conditions for fish in six connected back water lakes in Navigation Pool 5 of the upper Missouri River. The primary management objective is to improve water temperature, dissolved oxygen concentration and current velocity during winter for bluegills, Lepomis macrochirus, and black crappies, Pomoxis nigroma

Water resources data, Michigan, water year 1995
Water resources data for the 1995 water year for Michigan consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and ground water levels. This report contains discharge records for 148 streamflow-gaging stations; stage only records for 2 stream-gaging stations and 19 lake-gaging stations; stage and contents for 4 lakes and reservoirs; wat

Ground-water levels in Huron County, Michigan, January 1995 through December 1995
In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into an agreement to continue collecting water levels at selected wells throughout Huron County. As part of the agreement, the USGS has provided training and instrumentation for County personnel to measure, on a quarterly basis, the de

Hydrogeologic framework of Pennsylvanian and Late Mississippian rocks in the central lower peninsula of Michigan
Late Mississippian and Pennsylvanian sedimentary rocks form part of a regional system of aquifers and confining units in the central Lower Peninsula of Michigan. The upper part of the Pennsylvanian rock sequence constitutes the Saginaw aquifer, which consists primarily of sandstone. This sandstone aquifer overlies the Saginaw confining unit, which consists primarily of shale. The Saginaw confining

Selected geochemical characteristics of ground water from the Glaciofluvial aquifer in the central Lower Peninsula of Michigan
Chemical and stable-isotope data for water from wells completed in the Glaciofluvial aquifer in the central Lower Peninsula of Michigan were used to prepare maps that show the areal variation of 8180; distribution of dissolved solids, dissolved chloride, dissolved iron, and dissolved sulfate; and distribution of hydrochemical facies. Delta oxygen-18 values indicate the presence of modem meteoric w

Hydrology, water quality, and effects of drought in Monroe County, Michigan
Monroe County relies heavily on its aquifers and streams for drinking water, irrigation, and other ~ses; however, increased water use, high concentrations of certain constituents in ground water, and droughts may limit the availability of water resources. Although the most densely populated parts of the county use water from the Great Lakes, large amounts of ground water are withdrawn for quarry d

Predevelopment freshwater heads in the glaciofluvial, Saginaw, and Marshall aquifers in the Michigan Basin
Maps showing predevelopment freshwater heads were developed for the major aquifers in the Michigan Basin. The Michigan Basin is an isolated, regional ground-water-flow system consisting of a glaciofluvial aquifer and three bedrock aquifers separated by confining units. The bedrock aquifers investigated are the Saginaw, Parma-Bayport, and Marshall aquifers. Fractured sandstones within the bedrock a

The Fox River PCB transport study: Stepping stone to a healthy Great Lakes ecosystem
Polychlorinated Biphenyls (PCBs) in the Great Lakes Despite being banned since the 1970's, polychlorinated biphenyls (PCBs) continue to pose a threat to the environment because of their persistence and toxicity to organisms ranging from minute algae to fish, waterfowl, and human beings. PCBs, a set of 209 related chlorinated organic compounds, had various industrial uses such as in hydraulic fluid

The application of an analytic element model to investigate groundwater-lake interactions at Pretty Lake, Wisconsin
Pretty Lake is a 64 acre, sandy-bottomed groundwater flow-through lake that has a history of hydrologic disturbance. Residents and regulators require a better understanding of lake-groundwater interaction to develop measures to protect the lake's hydrologic system and water quality. A groundwater flow model was constructed as a tool to synthesize field data collected at the site, delineate recharg

Test system for exposing fish to resuspended, contaminated sediment
We describe a new test system for exposing fish to resuspended sediments and associated contaminants. Test sediments were resuspended by revolving test chambers on rotating shafts driven by an electric motor. The timing, speed, and duration of test-chamber revolution were controlled by a rheostat and electronic timer. Each chamber held 45 litres of water and accommodated about 49 g of test fish. T
