Degradation of the city of Fremont's water supply reservoir has forced the city to seek alternative sources of water, and opened possibility of removal of the Ballville Dam that impounds the degraded reservoir. The Ballvile Dam currently creates a barrier to upstream fish movement in the Sandusky River, effectively eliminating access to the upper two thirds of the river. To assess the potential impacts of the removal of the Ballville Dam on fisheries resources in the Sandusky River, fish species composition was compared in areas above and below the dam. Fish assemblages were similar above and below the dam. Forty-six fish species were sampled in the study area below the dam compared to 53 fish species sampled above the dam. The dam does not appear to be actively blocking the upstream expansion of harmful nonindigenous fish species, however this is more likely due to the lack of suitable habitat within the river.
