Preconstruction Assessment of Biological Quality of the Chena and Little Chena Rivers in the Vicinity of Chena Lakes Flood Control Project Near Fairbanks, Alaska.
Abstract
Chemical and biological data were collected on the Chena and Little Chena Rivers from October 1972 through August 1973 to determine the water quality of these rivers prior to construction of the Moose Creek and Littl Chena Dams by the U.S. Army Corps of Engineers. Chemical-quality measurements included conductivity, alkalinity, pH, dissolved oxygen, nitrogen and phosphorous species, dissolved iron, and biochemical and chemical oxygen demand. Biological measurements included a semiquantitative and qualitative assessment of benthic invertebrates, periphyton, and phytoplankton. The results indicate a typical clean-water subarctic stream with excellent water-quality characteristics. The chemical and biological water-quality constituents in the studied reach of the Chena and Little Chena Rivers are relatively uniform with the possible exception of iron and chemical oxygen demand which seems to increase downstream.
