Record-breaking floods on Sept. 13, 1971, occurred in some urbanized basins of southeastern Pennsylvania. This flooding resulted from heavy, intermittent thunderstorms on Sept. 11-13, 1971, which produced 8 to 12 inches of rainfall in the basins of Skippack, Stony, and Chester Creeks. Rain was heaviest during mid-day of the 13th. Damage to homes, businesses, and public property amounted to many mi

The water resources were studied within an area whose natural ground-water flow is largely towards the center of the metropolitan area. This area coincides with the extent of the Hinckley Sandstone aquifer. Thus, the general geohydrology of the area bounded by the extent of the Hinckley Sandstone (about 6,000 square miles) as it relates to the hydrology of the Minneapolis-St. Paul metropolitan are

Flood peaks with magnitudes from 2 to 3 times the SO-year flood occurred on streams in the Little Maquoketa River basin for the flood of August 2, 1972. Up to nine inches of rain fell in the headwater of the Middle Fork tributary with six to seven inches occurring over most of the Little Maquoketa River basin. The flood peak elevation at the gaging station near Durango exceeded the 1925 flood of r

Flood information is reported for 207 miles of the main stem, 23 miles on the West Branch, and 23 miles on the East Branch, of the Iowa River. The information will be of use to those concerned with the design of bridges and other structures and the conduct of various operations on the flood plains of the streams. Included in the report are flood-peak records, gaging-station records, and water-surf

The purpose of this report is to describe the physical environment, availability, characteristics, distribution, movement, and quailty of water in the Pecatonica-Sugar River basin.  In addition, water use and water problems are summarized to give an understanding of man's management of water within the basin.

Rapid City, the second largest city in South Dakota, is located at the eastern edge of the Black Hills about 9 miles downstream from Pactola Dam.  It is bisected laterally by Rapid Creek, and longitudinally by the eastern flank of the Black Hills.  Canyon Lake, a samll recreation reservior having a surface area of 35 to 40 acres, is located near the west city limits on Rapid Creek.  The floods of

This atlas presents data on the areal and vertical distribution of the dissolved-solids and fluoride concentrations in ground water for the lower Colorado River region, an area of about 140,000 square miles in parts of Arizona, Nevada, New Mexico, and Utah. The maps were prepared using data from previously established reports, data collected by other Federal, State, and local agencies, and data fr

The purpose of this report is to describe the water resources of the Menominee-Oconto - Peshtigo River basin in Wisconsin in order to aid in planning future water management in the basin and in nearby areas. The physical setting, availability, distribution, movement, quality, and use of water are discussed. The report presents general information on the basin that was derived from data obtained fr
