| Abstract: | A two-year study made in Redwood National Park, Calif., (September 1973-September 1975) determined existing chemical water-quality conditions and identified possible effects of logging on water quality in streams. Water quality was generally good, with dissolved-solids concentrations ranging from 25 to 139 milligrams per liter in the Redwood Creek basin and 21 to 49 milligrams per liter in the Mill Creek basin. Water type and pH tended to shift seasonally. Exposure of soils to the elements in areas logged or having naturally sparse vegetation accelerated chemical weathering and increased dissolved-solids concentrations. Nitrogen and phosphorus concentrations were generally too low to support nuisance algae, but were higher in logged areas. Higher nitrogen concentrations in areas well exposed to sunlight could support modest algae populations. Trace-metal concentrations were low, typical of clean streams. (Woodard-USGS) |
