Selected hydrologic relationships for Soldier Creek, northeastern Kansas
William J. Carswell Jr.
1981, Water-Resources Investigations Report 81-8
Hydrologic data from Soldier Creek basin were compared with relations from statewide data. The quantity and quality of streamflow were affected mostly by soils, slopes, and land use. Average annual precipitation during the study (196476) was 35.12 inches, or 2.3 percent greater than the long-term (1929-76) average. The average streamflow...

Water-quality assessment of the Merced River, California, in the 1977 water year
Stephen K. Sorenson, Ray J. Hoffman
1981, Water-Resources Investigations Report 80-75
Water-quality conditions in the Merced River in California were sampled four times during the 1977 water year at 12 stations on the river and its major impoundments. Samples taken at the record or near-record low flows of the 1976-77 drought, showed that calcium and bicarbonate were the predominant ions in...
