Changes in quality of ground water in the Lincoln area, Montana, 1974-79
Robert B. Leonard, Wayne A. Wood, Arnold J. Boettcher
1981, Open-File Report 80-1108
Water samples from representative shallow wells in the vicinity of Lincoln, Montana, were collected during March and June 1979 for analysis to evaluate changes in quality since 1974-75 and possible contamination by domestic or agricultural waste. All samples were suitable for drinking water with respect to the constituents tested. Tests...

Erosion and sedimentation in the Kenai River, Alaska
Kevin M. Scott
1981, Open-File Report 81-219
The Kenai River system is the most important freshwater fishery in Alaska. The flow regime is characterized by high summer flow of glacial meltwater and periodic flooding caused by sudden releases of glacier-dammed lakes in the headwaters. Throughout most of its 50-mile course across the Kenai Peninsula Lowlands to Cook...

1981, Open-File Report 81-207
Sediment samples were collected on the South Platte, North Platte, and Platte Rivers in Colorado and Nebraska during the 1979 and 1980 runoff seasons. Suspended-sediment concentrations ranged from 62 to 3,705 milligrams per liter and the maximum load was 45,547 metric tons per day. The percentage of suspended sediment samller...

1981, Open-File Report 81-1188
A stochastic model is developed to simulate flows for three seasons (September through February, March and April, May through August) at Overton, Odessa, and Grand Island, Nebraska on the Platte River. The model preserves the first and second order moment properties of the historical flow series, including significant autocorrelations within...
