5. 5 Consequences of Dams Blocked migration of American shad, River Herring, Sturgeon, American Eel, etc. Project operations affect habitat within the watershed

6. Susquehanna River Hydroelectric Projects 6 History of Upstream Passage 1972- Conowingo West Fish Lift 1991- Conowingo East Fish Lift 1997- Fish Lifts at Holtwood and Safe Harbor 2000- Vertical-slot ladder in operation at York Haven

8. 8 FERC Relicensing Holtwood received license amendment, to make major modifications, increase generation and improve fish passage York Haven, Muddy Run, and Conowingo started re-licensing in 2009 (2014)

9. Susquehanna River Hydroelectric Projects 9 Study Requests Cooperative effort of: –Maryland DNR, –Pennsylvania Fish and Boat Commission, –Pennsylvania DEP –Susquehanna River Basin Commission –US Fish & Wildlife Service Concerns –Environmental, –Fisheries / biological, and –Recreation

10. Susquehanna River Hydroelectric Projects 10 Conowingo/Muddy Run Studies 32 Pre-licensing studies: Ongoing (2010-2011) –Fish passage (including eels): efficiency & capacity –Flow management: minimum flows & pond levels –Recreation and land management –Water quality: D.O. / sediments / nutrients –Biological surveys: mussels, sturgeon, eagles, etc.

11. Susquehanna River Hydroelectric Projects 11 The Challenge? To gather all necessary data / information during the study period in order to develop well-informed, adaptive, licensing conditions This process will ultimately establish the fate of Susquehanna River fish stocks at least through the year 2044!! (Maybe 2064??)
