1983, Water-Resources Investigations Report 82-4124
Somerville Lake in south-central Texas is a shallow lake, with a mean depth of 14 feet. The maximum depth of the submerged channel of Yegua Creek is usually less than 35 feet and in most areas of the lake the depth is less than 10 feet. Several factors including thermal circulation...
Ground-water quality in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho
D. J. Parliman
1983, Water-Resources Investigations Report 83-4062
Water-quality data were collected from 92 wells in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho. Current data were compiled with pre-1980 data from 116 wells to define water-quality conditions in major aquifers. Factors affecting water quality are composition of aquifer materials, water temperature, and source of...

Meteorological, water-temperature, and discharge data for the Mattole River basin, Humboldt County, California
R.D. Noble, Alan P. Jackman
1983, Water-Resources Investigations Report 78-81
To overcome a major difficulty in the testing of the validity of river-temperature models - the lack of adequate precise synoptic data for an entire river basin - synoptic meteorologic, water-temperature, and discharge data were obtained in the Mattole River Basin in northern California during the period June 10 through...
Reconnaissance of surface-water resources in the Kobuk River basin, Alaska, 1979-80
J.M. Childers, D.R. Kernodle
1983, Water-Resources Investigations Report 83-4027
Surface water data were collected at selected sites in the Kobuk River Basin in northwest Alaska in August 1979 and April 1980. In August 1979, frequent heavy rains caused abnormally high flows in the basin; unit runoff values, computed from discharge measurements at 25 sites, ranged from 0.08 to 12.2...
Chloride concentrations in the coastal margin of the Floridan Aquifer, southwest Florida
K.W. Causseaux, J. D. Fretwell
1983, Water-Resources Investigations Report 82-4070
The Floridan aquifer is the principal source of freshwater supply in southwest Florida. The freshwater part of the aquifer is underlain by saltwater in lower formations and is bounded on the west by saltwater in the coastal parts of the aquifer. A zone of mixing lies between the saltwater and...
