Rainfall in excess of 10 inches occurred during the first 5 days of November 1985, resulting in devastating flooding in the Mid-Atlantic states of West Virginia, Pennsylvania, Maryland, and Virginia. Throughout the area, many streams exceeded previously known flood heights and discharges and, in many cases, the recurrence interval of peak discharges exceeded 100 years. The peak stage and discha

The investigation of sediment deposition in Lake Corpus Christi was initiated by researching the published and unpublished sediment data for the 1972-85 water years for stations located upstream and downstream of the lake. Regression analysis was used to fill in the missing data. Data were tabulated for monthly discharge (acre-feet) and sediment load (tons, acre-feet, and percent by weight). Yearl

This report presents stations descriptions and tables of peak stages and discharges for 280 continuous- and partial-record gaging stations in Iowa. Data for the annual flood series for each gaging station and partial-duration series, at stations where available, are contained in the report.

The effects of dewatering a proposed zinc and copper mine on water levels of four lakes near Crandon, Wisconsin, were predicted by use of a digital water-budget model of the lakes. The average lake-stage reduction predicted by the model for expected ground-water levels after mine dewatering ranged from 0.21 feet for Duck Lake to 6.9 feet for Little Sand Lake. These stage reductions assume that no

Water year 1986 was the second wettest on record in Iowa since records began being kept in the late 1800's. This report examines the spatial distribution of precipitation, the deviations from normal precipitation, and the effect of the excess precipitation on the water resources of Iowa. New high ground-water levels were established in water wells and new peak stages and new peak discharges were e

Water-quality data were collected at five sites on Orwell Reservoir and two sites on the Otter Tail River, at the inflow and outflow points of the reservoir. The data, collected from April 1983 to July 1966, consist mainly of streamflow and nutrient concentrations at the river sites and nutrient concentrations, alkalinity, Secchi-disk transparency, phytoplankton counts, chlorophyll concentrations,

This report contains summaries of the progress of water-resources studies in Utah by the U.S. Geological Survey, Water Resources Division, Utah District, from July 1, 1985 to June 30, 1986. The program in Utah during this period consisted of 22 projects, and a discussion of each project is given in the main body of the report. Short descriptions are given at the end of the report for six proposed

This report contains summary information on ground-water quality in one of the 50 States, Puerto Rico, the Virgin Islands, or the Trust Territories of the Pacific Islands, Saipan, Guam, and American Samoa. The material is extracted from the manuscript of the 1986 National Water Summary, and with the exception of the illustrations, which will be reproduced in multi-color in the 1986 National Water

Three sets of seepage measurements were made at ten canal sites and at all turnouts along a 15.3-mile section of the Central Utah Canal during the sumner of 1986. The total loss for the 15.3-mile section averaged about 36 cubic feet per second or 2.4 cubic feet per second per mile. The nine subsections were grouped into five reaches of one or more subsections with similar losses per mile. Average
