Illinois Waters Bibliography: River Basin Water Quality Assessments (INHS, 1977-1979)

A directory of documents on Illinois waters

During the 1970s, the Illinois Natural History Survey performed intensive sampling of aquatic biota in Illinois Watersheds in order to assess water quality in those watersheds for the Illinois Environmental Protection Agency.  The sampling effort targeted known pollution sources, and reported a high number of unbalanced and semi-polluted stream segments in all basins sampled.
