The White River Mainstein Project was completed in the summer and fall of 2020 to assess the health of the West Fork White River :ind White River (WR) from headwaters to confluence. The Indiana Department of Environmental Management. Indiana Department of Natural Resources. and Muncie Sunitary District Bureau of Water Quality sampled 405 river miles. resulting in 62 fish community surveys yielding 17.232 fish comprising 94 species. The Index of Biotic integrity (IBI) was calculated for every sample, and the average [BI score was 41. with 79% of IBI scores above or equal to 36, indicating they can support healthy fish populations. Thirteen sites. many in the lower reaches of the White River, had IBI scores below 36, indicating fish populations are impaired. The Qualitative Habitat Evaluation Index (QHEI) was also used at each site to assess the available habitat for the fish community with 79% of sites fulling within the good or excellent category and only one site fulling into the poor category . Results from this project will serve us a benchmark of fish communities, water quality, and aquatic habitat found in 2020.
