Charles E. Sloan
1972, Open-File Report 72-348
A hydrologic reconnaissance was made of Anaktuvuk pass in the central Brooks Range during the summer of 1971 to help develop a water supply for the village school. Winter icings and summer flow conditions in Contact Creek both indicate that ground water is present beneath the creek bed. A well-site...

George Porterfield
1972, Open-File Report 72-302
Average annual sediment discharge in Pacheco Creek basin, Contra Costa County, Calif., was larger during August 1965-April 1970 than the historical annual sediment discharge (1909-62) by a factor of about 1.3. This increas in sediment discharge is attributed primarily to an increased frequency of peak streamflows and to a larger...

1972, Journal of the Fisheries Research Board of Canada (29) 199-202
In laboratory flowing-water troughs exposure required to induce 100% mortality, regardless of time to death for antimycin and rotenone against selected freshwater fish species was determined. Carp and white suckers required shorter exposures to antimycin (6 hr) than to rotenone (18–24 hr) at field-use concentrations of 5 and 50 ppb respectively. Bullheads were...
