In 2018, the Ballville Dam was removed from the Sandusky River, Ohio. The removal of the dam was expected to reconnect areas of upstream habitat, restore fish passage, and improve the fish community. To assess the quantity and quality of available walleye spawning habitat post-dam removal, a habitat suitability index (HSI) model was developed. Model results indicated that there is more walleye spawning habitat upstream of the former dam. Electrofishing surveys were conducted during the spring of 2020 and 2021 (to assess migratory fish passage above the dam) and during summer 2020 (to assess the resident fish community). Walleye were captured upstream of the dam during the 2021 spawning run. Overall, walleye and white bass catch rates and spawn run strengths were lower in post-assessments compared to values seen pre-dam removal. The results of the 2020 post-assessment suggest that the quality of the resident fish community has declined across the study area since the 2009 pre-assessment. However, changes in habitat quality between assessments were less apparent. This study documents the short-term effects of dam removal on river conditions and the fish community post-dam removal.
