Evaluating Water Temperature, Habitat, and Fish Communities in Candidate Coolwater Streams in Illinois Annual Project Report 2009

Work during this reporting period focused on characterizing temperature, habitat, and biological communities at candidate coolwater sites. During the past year we have collected additional temperature data from 48 candidate streams and other locations and now have records from 188 stream reaches. Sixty-three sites in Illinois have been identified as cool- or coldwater based on these records. Physical habitat surveys have been conducted at 68 sites where temperature data were available. Fish and macroinvertebrate data were obtained from the cooperative basin survey program data managers for candidate sites whenever possible and added to collections made during previous project years. This report summarizes progress for the period beginning 1 October 2008 and ending 30 September 2009. Additional analyses associated with this project are ongoing and results will be presented in a final report to be submitted upon completion of this project.
