Limnological studies of the major streams in Chester County, Pennsylvania Limnological studies of the major streams in Chester County, Pennsylvania

The major streams in Chester County, Pennsylvania were studied to determine their environmental state, and to relate this condition to land- use patterns. A biological numerical rating system on a scale of 1 to 10 was developed to classify stream conditions. One indicates extremely toxic conditions and 10 balanced biological conditions. The majority of the streams studied had ratings...

Water-quality study of Tulpehocken Creek, Berks County, Pennsylvania, prior to impoundment of Blue Marsh Lake Water-quality study of Tulpehocken Creek, Berks County, Pennsylvania, prior to impoundment of Blue Marsh Lake

Blue Marsh Lake is planned as a multipurpose impoundment to be constructed on Tulpehocken Creek near Bernville, Berks County, Pennsylvania. Prior to construction, samples of water, bed material, and soil were collected throughout the impoundment site to determine concentrations of nutrients, insecticides, trace metals, suspended sediment, and bacteria. Analyses of water suggest the...

Ground-water resources of Chester County, Pennsylvania Ground-water resources of Chester County, Pennsylvania

Fifty gallons per minute (3 liters per second) or more may be obtained from wells in almost all parts of the county, but not at all locations. Adequate exploration to find fracture or solution openings is required. Five hundred gallons per minute (30 liters per second) or more may be obtained from some of the carbonate rocks. Linear features are visible on 1:1,000,000-to 1:24,000-scale...

Selected hydrologic data, Chester County, Pennsylvania Selected hydrologic data, Chester County, Pennsylvania

This report presents selected hydrologic data collected during a study of the ground-water resources of Chester County, Pennsylvania. The study was made during 1973-76 by the U. S. Geological Survey in cooperation with the Chester County Water Resources Authority. This report is intended to make the data conveniently available and to supplement an interpretive report that will be...

Preliminary results of preimpoundment water-quality studies in the Tioga River Basin, Pennsylvania and New York Preliminary results of preimpoundment water-quality studies in the Tioga River Basin, Pennsylvania and New York

The Tioga River and its major tributaries were sampled monthly from September 1973 to May 1975. Water quality in the Tioga River is degraded by acid-mine drainage entering the stream near Blossburg from both strip- and deep-mined areas. The stream supports few species of aquatic life from Blossburg to its confluence with Crooked Creek. Alkaline water of tributaries Mill Creek, Crooked...

Selected hydrologic data, Clarion River and Redbank Creek basins, northwestern Pennsylvania: an interim report Selected hydrologic data, Clarion River and Redbank Creek basins, northwestern Pennsylvania: an interim report

This report presents basic hydrologic data collected for part of a water-resources study and supplements an interpretive report which will be published separately. The report summarizes discharge data from 140 stream collection sites, contains tables of about 800 chemical analyses from 164 stream sites and 107 analyses from 91 abandoned flowing oil and gas wells including concentrations...

Hydrology and sedimentation of Bixler Run Basin, central Pennsylvania Hydrology and sedimentation of Bixler Run Basin, central Pennsylvania

Rainfall, streamflow, stream chemical, and sediment discharge data were collected from Bixler Run near Loysville, Pa., during the period from February 1954 to September 1969 as part of a project to evaluate sediment discharge from an agricultural area in which soil-conservation techniques were being adopted at a moderate rate. The study was conducted by the U.S. Geological Survey in...

Limnological data for the major streams in Chester County, Pennsylvania Limnological data for the major streams in Chester County, Pennsylvania

Limnological data on major streams in Chester County, Pennsylvania are tabulated to provide a base line as to the present stream conditions. As land-use patterns change and further urbanization takes place, it is anticipated that these data will serve as a basis for comparison of conditions in the future. The 13 basins encompass a total drainage area of 1,812 km2 (697 mi2) of the 1,976...

Preimpoundment water quality of Raystown Branch Juniata River and six tributary streams, south-central Pennsylvania Preimpoundment water quality of Raystown Branch Juniata River and six tributary streams, south-central Pennsylvania

The Raystown Branch Juniata River watershed, which is the main water source for Raystown Lake, is a 960-square-mile (2,490 square kilometres) drainage basin in south-central Pennsylvania. Preimpoundment water-quality data were collected on the Raystown Branch and six tributary st.reams in the basin. Specific conductance values varied inversely with water discharge. The pH values were...

Technical manual for estimating low-flow frequency characteristics of streams in the Susquehanna River basin Technical manual for estimating low-flow frequency characteristics of streams in the Susquehanna River basin

This report presents procedures for estimating low-flow frequency characteristics for streams in the Susquehanna River basin. The techniques can be used at ungaged sites as well as sites where insufficient data are available to make a reliable estimate. Streams have been divided intp two types--major and minor. Major streams are the Susquehanna, West Branch Susquehanna, Juniata, and...
