Intensive survey of the Eagle Creek basin, Saline and Gallatin Counties, Illinois, 1986-1987
The Eagle Creek Watershed, south of Harrisburg in southern Illinois has historically been impacted from extensive coal-mining operations. Knowledge of the stream-quality problems caused by mining activities prompted designation of this stream as a priority water body in the 1982-1983 Illinois Water Quality Report (IEPA 1984). In late summer 1986, a stream quality investigation was initiated to determine the current status of Eagle Creek. Aquatic macroinvertebrate and water-quality samples were collected from eight locations in the Eagle Creek watershed; fish populations, stream habitat and sediment chemistry were assessed at selected basin sites (Appendix Table A). Objectives of this assessment were to: Document ambient water-quality conditions and any problems resulting from coal-mining activities in the basin; Evaluate biotic integrity in the basin using aquatic macroinvertebrate and fish communities; Determine aquatic-life use support attainment and factors causing or contributing to use impairment; Assign a Biological Stream Characterization (BSC) rating to stream segments assessed; and Determine sediment chemistry characteristics and document constituents present at abnormal levels.
