An Index of Biotic Integrity (113I) was developed to assess the condition of wadeable streams in the Piedmont ecoregion of Georgia based on the fish communities present. Data collected from 181 sample sites throughout six major drainage basins were used to develop Maximum Species Richness plots and scoring criteria for 13 IBI metrics. Potential Piedmont reference sites were identified and will undergo long- term trend monitoring. Samples collected in 1998 and 1999 resulted in the listing of 12 stream segments to the Environmental Protection Division's list of impaired waters and the de-listing of 40 other stream segments.
