| Abstract: | This report, on water quality for streams in Crawford and Perry Counties, Indiana, defines the variation in concentrations of nutrients, inorganic constituents, suspended sediment, bacteria, and phytoplankton in streams, and chlorinated hydrocarbons in bed materials in the Middle Fork Anderson River watershed; identifies areas and sources of water-quality problems; and determines the effects of existing flood-retarding structures on water quality. The data base for this water-quality assessment included five sets of samples collected from September 1975 through July 1976. Temperature, specific conductance, pH, and dissolved-oxygen concentration of water were measured, and stream discharge was estimated at 25 sites. Samples for laboratory analysis were collected at 9 of these sites in September 1975, at 8 of the sites in December 1975, and at 7 of the sites in March, June, and July 1976. Surface-water quality in the watershed is generally good except for problem-causing concentrations of bacteria, dissolved oxygen, and phosphorus at some sites along the main stem during low flow, and manganese at most sites year-round.
