Biological Criteria Development for Large Rivers with an Emphasis on anAssessment of the White River Drainage, Indiana

摘要

The White River drainage was investigated during 1990-1991 to determine waterresource expectations for large rivers. A total of 49 sites were sampled within three watersheds to develop and calibrate an Index of Biotic Integrity for use in Indiana large rivers. The lower White River showed a highly skewed IBI indicating lower extremes in water resource integrity. The trend in the East and West Forks was toward declining biological integrity with increasing drainage area. Site specific data including an evaluation of fishery community trends, tolerance classifications, trophic and reproductive guides are included.
