This study characterizes the clay minerals in sediments associated with a plume of creosote-contaminated groundwater. The plume of contaminated groundwater near Pensacola, FL, is in shallow, permeable, Miocene to Holocene quartz sand and flows southward toward Pensacola Bay. Clay-size fractions were separated from 41 cores, chiefly split-spoon samples at 13 drill sites. The most striking...

Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Those climatic data needed for energy budget and mass transfer studies are presented , including: water surface temperature, dry-bulb and wet-bulb air temperatures, wind speed, precipitation, and solar and atmospheric radiation. Some calculated values necessary for these studies are also...

Estimates of runoff for 56 sites within the Shenandoah National Park were made by the U.S. Geological Survey for the Direct/Delayed Response Project that is being conducted by the U.S. Environmental Protection Agency. The purpose of that project is to determine the long-term effects of acidic deposition on surface-water chemistry. Runoff was estimated for the period July 18,1981, through...

Water resources data for the 1987 water year for Michigan consists of records of stage, stage and contents of lakes and discharge, and water quality of streams; reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 135 streamflow-gaging stations; stage only records for 15 lake-gaging stations; stage and contents for 5 lakes and...

Aquaculture supports a large sportfishing industry in Minnesota. Licensed fish farms that hatch and (or) harvest minnows or gamefish are located throughout the State. The volume of water used in these operations can be expressed as the minimum capacity per pound of fish, total water consumed, total water dedicated to the farming operation, or total water withdrawn. In expressing water...

Log-Pearson type III flood-frequency analyses were made of annual series peak-flow records from 246 gaging stations on unregulated streams in Minnesota having watersheds ranging in area from 0.08 to 2,520 square miles. These flood discharges were related to watershed and climatic characteristics by using multiple-regression techniques. On the basis of this preliminary regression analysis...

Nearly 700 million gallons of ground water are withdrawn every day in Minnesota, mostly for public supply, irrigation, and domestic and commercial use. About 94 percent of the public water-supply systems in the State use ground water and 75 percent of all Minnesotans obtain their domestic supplies from ground water. The major issues related to this important resource in Minnesota are:

The Apostle Islands National Lakeshore consists of 21 islands, part of the Bayfield Peninsula, and the adjacent waters of Lake Superior. Selected water resources of the Apostle Islands National Lakeshore were assessed to aid the National Park Service in developing and managing the Lakeshore and to provide a data base against which future changes can be compared. This summary of water...

Water levels, locations, depths, and aquifers tapped are given for 112 observation wells. Tabulated data include extremes of water levels for calendar year 1986 and for the period of record, pumpage of most major groundwater users in the State, and water-quality data from selected wells. The largest reported user of ground-water, the city of Lansing, pumped 7.6 billion gallons from the...

Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: water-surface temperature, dry-bulb and wet-bulb air temperatures, wind speed, precipitation, and solar and atmospheric radiation. Some calculated values necessary for these studies, such...

Since the 1976-77 drought in Minnesota, legislators, planners, and citizens have become aware of the need for water management based on knowledge of water availability and use in order to alleviate local water shortages. In addition to maintaining an adequate supply, information on the amount of water used, where it is used, and how it is used is needed to help resolve problems of...

Water transfer data were collected by the U.S. Geological Survey , in cooperation with the Minnesota Department of Natural Resources, from the 13 hydrologic subregions in Minnesota. About 30,000 acre-ft of water is exported annually from eight of these subregions. Interbasin transfer of water is classified according to type of water conveyance in Minnesota. This information is needed by...
