A complete program of stream reclamation was developed and applied on Indian and Abrams creeks in Great Smoky Mountains National Park. A salt-resistivity technique was used to estimate the dilution and velocity of a toxicant in running water. Streamside toxicity trials on resident fishes established minimal, effective concentrations of the rotenone material. The successful removals of undesirable

A portable resistivity (or conductivity) meter is easily used in fishery investigations to obtain rapid and precise measurements of the electrical resistance (or conductance) of waters. These measurements can be used to estimate the total dissolved solids content of waters, to facilitate the selection of appropriate gear for efficient electrofishing, and to determine the velocity, stretch-out, dil

The visual-tube method for sedimentation analysis of sands was developed as a part of the general investigation titled "A Study of Methods Used in Measurement and Analysis of Sediment Loads in Streams." The method is one answer to the need for a simple, rapid, and inexpensive means of determining the sedimentation-size frequency analysis of sand samples containing particles less than one millimete

Outagamie County is in east-central Wisconsin. It has no serious groundwater problem at present, but the county is important as a recharge area for the principal aquifers supplying water to Brown County and industrial Green Bay to the east. The county is covered by glacial drift and lake deposits of the Wisconsin stage of glaciation. In the northwestern quarter of the county these deposits rest up

Sixty-eight electrical depth profiles were completed in the vicinity of Neillsville, Wis. to obtain information on the water-bearing beds in the glacial moraine and consolidated sedimentary rocks in the area. No productive aquifers were found but the best areas for test drilling are described. The basic theory and interpretation procedures, together with a short description of field methods on ele

Glacial outwash sand and gravel deposits are the principal aquifer in southwestern Langlade County, Wis. The underlying bedrock of pre-Cambrian age contains little or no water. The source of ground water is local precipitation. Information was collected on more than 300 wells in the area. Movement of ground water is generally southward and locally toward streams. Discharge is by streams and subsur

The area covered by this report comprises a square which measures three townships on a side and enclose 318 square miles in southeastern Oakland County. The investigation of the ground-water resources of this area was made by the U.S. Geological Survey in cooperation with the Detroit Metropolitan Area Regional Planning Commission, the Michigan Department of Conservation, and the Michigan Water Res
