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...
Analyses of water, bank material, bottom material, and elutriate samples collected near Belzoni, Mississippi (upper Yazoo projects)
David B. Brightbill, Joseph B. Treadway
1980, Open-File Report 80-758
Four core-material-sampling sites and one bottom-material site were chosen by the U.S. Army Corps of Engineers to represent areas of proposed dredging activity along a 24.9-mile reach of the upper Yazoo River. Five receiving-water sites also were selected to represent the water that will contact the proposed dredged material. Chemical...

On May 25-26, May 30-June 2, and June 12-13, 1980, strong, high-altitude winds from the north occurred during periods of volcanic-ash eruption at Mount St. Helens in southwestern Washington. As a result, ash fell in the Bull Run watershed, Oregon, some 50 miles to the south, the principal water-supply source...
Estimation of background loadings and concentrations of phosphorus for lakes in the Puget Sound region, Washington
Robert J. Gilliom
1980, Open-File Report 80-328
For lakes in watersheds that include developed land, evaluation of eutrophication is facilitated by knowledge of changes in the lakes ' phosphorus concentration since development. A method is described for estimating background phosphorus concentration in lakes of the Puget Sound lowland, Washington. Using a mass-balance ' Vollenweider-type ' model, phosphorus...
