Map showing drainage basins and locations of streamflow-measuring sites, Fairfax County, Virginia
E. H. Mohler
1977, Open-File Report 77-270
A drainage basin map of Fairfax County shows basins for named streams with drainage areas of 1.1 sq mi (2.8 sq km) or more. Areas of minor streams draining directly into the Potomac River and Occoquan Creek are tabulated. The locations of continuous-record and partial-record (peak-flow and low-flow) flow sites...

Estimating the magnitude and frequency of floods on natural-flow streams in Massachusetts
S. William Wandle Jr.
1977, Water-Resources Investigations Report 77-39
The magnitude and frequency of floods on natural-flow streams in Massachusetts, with drainage areas between 0.25 square mile and 497 square miles, may be estimated from drainage area, main channel slope, a precipitation index, and a storage factor. Multiple-regression techniques were used to define the relationship between basin and climatic...
Time of travel of solutes in selected reaches of Ohio streams, 1973 and 1975
Arthur O. Westfall
1977, Water-Resources Investigations Report 77-116
The basic field data for time-of-travel measurements on six streams in Ohio are presented. In general, additional data on stream cross sections, tributary inflows, and chemical analyses for mainstream and tributary flows are given. Insufficient data were obtained to establish time-distance or time-discharge relationships....
Heavy metal discharges into Shasta Lake and Keswick reservoirs on the upper Sacramento River, California; a reconnaissance during low flow

1977, Water-Resources Investigations Report 76-49
Four out of seventeen streams entering the Shasta-Keswick Reservoir system in California contribute up to 94 percent of the heavy metal load into the upper Sacramento River under the low flow conditions which existed in the fall of 1974. Of these four streams, three contain acid mine drainage, with Spring...
