Johnstown-western Pennsylvania storms and floods of July 19-20, 1977

Widespread thunderstorms associated with two major squall lines, moved across Pennsylvania between the afternoon of July 19 and morning of July 20, 1977. The western part of outflow boundary produced by the second line became almost stationary in western Pennsylvania and resulted in 6 to 9 hours of nearly continuous thunderstorms. More than 6 inches of rain fell over a 400-square-mile area during

Sedimentation in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 to June 1980

Parts of the East Branch Mahoning Creek basin, a forested area of 29.6 square miles in west-central Pennsylvania, are disturbed by farming, surface mining, unpaved haul roads, eroding reclaimed areas, and logging. Streamflow was measured and water samples collected at a site upstream from the mouth from June 1979 to June 1980 during base flow and storm periods to evaluate sediment discharges. An a

Evaluation of the streamflow-data program in Pennsylvania

The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information requires knowledge of

Ground-water quality and data on wells and springs in Pennsylvania; Volume III, Delaware River basin

Volume III presents ground-water quality and physical data on about 1,250 wells and springs in the Delaware River Basin in Pennsylvania. Locations are shown on site-location maps derived from the hydrologic unit map. Codes showing the geologic age and aquifer are provided.

A stormwater management model for the West Branch Brandywine Creek, Chester County, Pennsylvania

Three subbasins in the West Branch Brandywine Creek watershed were modeled by the Dawby, Schaake, and Alley distributed routing rainfall- runoff model. The Honeybrook subbasin could not be calibrated because of nonrepresentative rainfall data. The Coatesville subbasin was calibrated, but not verified; the average standard error of estimate is 34 percent for peak discharge. The Modena subbasin was

Preimpoundment water quality in the Tioga River Basin, Pennsylvania and New York

The water quality in the Tioga River basin was studied from September 1973 to September 1978, prior to impoundment by the U.S. Army Corps of Engineers. Results of the investigation will be used in the operation of three reservoirs that were in the final stages of construction in late 1979. Annual suspended-sediment yields for the basin averaged 575 tons per square mile. Mill Creek near Tioga and C

Sample mine-site permit application (hydrologic assessment)

Hydrologic data are presented that may be useful in the permitapplication procedure required under current Office of Surface Mining regulations. The material is presented in a format which may serve as a guide for subsequent permit applications. Data on the quality and quantity of surface water and ground water for the mine plan, adjacent, and general areas are presented. The data are presented in

Quality of surface water in the coal-mining areas of western Maryland and adjacent areas of Pennsylvania and West Virginia from April 1979 to June 1980

The U.S. Geological Survey is studying the water quality of streams within the Eastern Coal Province. This report contains streamflow, water-quality, and biologic data collected in the North Branch Potomac River basin and in the Maryland portion of the Youghiogheny and Casselman River basins. Data collected from 64 streams from April 1979 to June 1980 are presented in tables. Other sources of hydr

Hydrology of Area 5, Eastern Coal Province, Pennsylvania, Maryland, and West Virginia

Hydrologic data are presented for area 5 of the Eastern Coal Province, the 7,384 square-mile Monongahela River basin in western Pennsylvania, western Maryland, and north-central West Virginia. One hundred thirty-four streams were sampled about three times during the 1979 and 1980 water years for specific conductance, pH, acidity, alkalinity dissolved and total iron, dissolved and total manganese,
