Technique for estimating magnitude and frequency of floods in Maryland
David H. Carpenter
1980, Open-File Report 80-1016
A method is presented for estimating flood magnitudes for natural drainage basins without urban development or regulated flow. The method was developed by multiple-regression techniques and applies to floods with recurrence intervals from 2 to 100 years.The State is divided into three regions, and sets of equations for calculating peak...

Water-resources reconnaissance of the southeastern part of St Paul Island, Pribilof Islands, Alaska
Alvin John Feulner
1980, Water-Resources Investigations Report 80-61
A hydrologic reconnaissance of the southeastern part of St. Paul Island, Pribilof Islands, Alaska, was made in August 1979 to determine if sufficient freshwater is available for a proposed harbor and fish-processing facility. Only three wells were being used in 1979, two by the community of St. Paul and one...

P.M. Merifield, D.L. Lamar
1980, Open-File Report 81-386
Beginning in October 1976, a program of water-level monitoring of abandoned water wells was initiated in the Palmdale area with the purpose of identifying possible water-level changes premonitory to a major earthquake on the San Andreas fault. In October 1977, the program was extended southeastward along the rift zone to...

Water-quality characteristics of selected lakes and reservoirs in Colorado
Linda J. Britton, Dennis A. Wentz
1980, Open-File Report 80-436
During the summers and autumns of 1973, 1974, and 1975, water-quality data were collected and compiled for 56 lakes and reservoirs in Colorado. The lakes and reservoirs sampled range from large reservoirs in the eastern part of the State to smaller natural lakes in the higher western parts of the...
Water-quality data for canals in eastern Broward County, Florida, 1975-78
W. H. Sonntag
1980, Open-File Report 80-68
Increased urbanization in Broward County has contributed to canals being used as receptacles for urban wastes, sewage effluent, and stormwater runoff. The introduction of contaminants into the canals may affect the water quality. In 1969 the U.S. Geological Survey, in cooperation with the Broward County Pollution Control Board and the...

A map, scale 1:20,000, shows water depths, rocks, and hazards to navigation. These data are noted on track lines run by the Research Vessel Growler in Alaskan waters, where data on navigation shown on published charts are nonexistant, preliminary, or out dated....
Composition and properties of the Pierre Shale and equivalent rocks, northern Great Plains region
Leonard Gene Schultz, H. A. Tourtelot, J. R. Gill, J.G. Boerngen
1980, Professional Paper 1064-B
The Pierre Shale and equivalent rocks of Late Cretaceous age consist in the east-central Dakotas of several hundred feet of offshore-marine shale and minor marl; in west-central Montana near the sediment source the equivalents of the Pierre Shale consist of several thousand feet of volcanic-rich and mostly nonmarine sediments; and...
Hydrologic setting of Williams Lake, Hubbard County, Minnesota
Donald I. Siegel, Thomas C. Winter
1980, Open-File Report 80-403
The hydrology and geology of Williams Lake watershed was studied to evaluate the accuracy of various methods used to determine precipitation and evaporation in lake water-balance studies and to define a lake and ground-water system according to approaches suggested by theoretical modeling studies. Regression analysis between estimated and measured precipitation...
Ground water in the Thousand Oaks area, Ventura County, California
