| Impact Description | As of 2005, over $75 million has been spent on restoring American Shad (Alosa sapidissima) populations in the Susquehanna River and mitigating the effects of dams. Establishment of Flathead Catfish and their depredation effects on shad would put this program, and the money invested into it, at risk. |
