Reconnaissance of water availability and quality in abandoned coal mines near Roslyn, Kittitas County, Washington
F. A. Packard
1981, Open-File Report 80-955
The recoverable volume of ground water in abandoned coal mines near Roslyn, Wash., is estimated to be 20,000 acre-feet. During times of drought, pumping this water into the Cle Elum and Yakima Rivers for use in irrigation downstream should present few major water-quality problems. Wells at seven locations should be...

1981, Open-File Report 81-681
The predevelopment steady-state ground-water flow system for 13 ,700 square miles of the Tertiary limestone aquifer system (known as the Florida aquifer in Florida) in east-central Florida is simulated by means of a digital computer model. The model results indicate that about 1,900 cubic feet per second recharges the aquifer...

Revised techniques for estimating magnitude and frequency of floods in Montana
Charles Parrett, R. J. Omang
1981, Open-File Report 81-917
Relations for estimating the flood magnitudes for ungaged sites in Montana have been updated. The State was divided into eight regions and separate multiple-regression equations for each region were developed that relate logarithms of annual flood magnitude to logarithms of basin characteristics for exceedance probabilities of 50, 20, 10, 4,...
Bed form distribution and inferred sand transport on Georges Bank
David C. Twichell
1981, Open-File Report 81-764
Four bed-form provinces have been identified on Georges Bank using sidescan sonar and echo-sounding techniques: large sand waves, small sand waves, megaripples, and featureless sea floor. The large sand waves are found on the bank crest where the surface tidal currents are strongest, and are bordered, north and south, by...
Results of exploratory drilling at Point MacKenzie, Alaska, 1981

The Matanuska-Susitna Borough anticipates industrial development near Point MacKenzie, Alaska. Because little hydrologic information is available for the area, the Borough contracted for the drilling of two test wells. It was found that: Both wells penetrated unconsolidated stratified clay, silt, sand, and gravel; each well penetrated a shallow unconfined and...
