Flow routing in the Susquehanna River Basin, Part II: Lowflow frequency characteristics of the Susquehanna River between Waverly, New York and Sunbury, Pennsylvania
Six flow-routing models were developed, calibrated, and verified for the Susquehanna River between Waverly, New York, and Sunbury , Pennsylvania. The models give the Susquehanna River Basin Commission tools to estimate effects of water-resource developments upstream from Waverly upon four gaged sites and two ungaged sites within the study reach. The models were used to simulate a 32-year record of

Flow routing in the Susquehanna River Basin: Part III -- Routing reservoir releases in the Tioga and Chemung rivers system, Pennsylvania, and New York, 1977
Channel-routing models were used to route hypothetical releases from reservoirs in the upper Tioga River basin, Pennsylvania. These releases were routed northward down the Tioga River to Lindley, Erwins, and Corning, New York: combined with flows routed down the Cohocton River from Campbell to Corning, New York; and then routed southeastward down the Chemung River from Corning to Chemung, New York

Mineral resources of the Big Frog Wilderness Study Area, Polk County, Tennessee and Fannin County, Georgia
The proposed Big Frog Wilderness is comprised of approximately 1820 hectares (18.2 km2) of mountainous terrain in the Cherokee and Chattahoochee National Forests south of the Ocoee River in Polk County, Tennessee, and Fannin County, Georgia. Rocks of the study area are greenschist-facies metasandstone, meta-arkose, metagraywacke, and dark slate of the Ocoee Supergroup of late Precambrian age. A ma

Ecological and physiological/toxicological effects of petroleum on aquatic birds: A summary of research activities FY76 through FY78
Oil and gas development and exploration in marine coastal areas and the Great Lakes will result in unavoidable spills of polluting oil. Although large oil spills may kill thousands of birds and stimulate much public concern, the bulk of oil that reaches aquatic environmentS released in the course of normal operations, with a total input into the world's oceans estimated at 6 million metric tons pe

Nonpoint-source discharges in Pequea Creek Basin, Pennsylvania, 1977
A study of Pequea Creek included measurement of streamflow and collection of water and bottom-material samples during selected base-flow and storm periods from February to December 1977. Samples were analyzed for nitrogen and phosphorus species, suspended sediment, organic carbon, and pesticides. Daily mean constituent concentrations and discharges transported from the basin were computed for a ga

Chemical and biological quality of selected lakes in Ohio, 1976 and 1977
Twenty-eight Ohio lakes (14 per year) were sampled by the U.S. Geological Survey and Ohio Environmental Protection Agency for the water-quality characteristics during the spring and summer of 1976 and 1977. Data items included: profiles of temperature, dissolved oxygen, pH, and specific conductance; physical, biological, nutrient, and organic characteristics; major and minor constituents; and phys
