Major scientific questions on the effects of Conowingo Hydroelectric Project and Muddy Run Pumped Storage Project operations on the aquatic communities of the Susquehanna River may be answered in the next two years.  Larry Miller, Project Leader of the Mid-Atlantic Fisheries Office took the lead on requesting studies. He was assisted by the Chesapeake Bay Field Office's biologists Janet Norman, Craig Koppie, and Andy Moser. 

 As part of the relicensing process for 30- 50 year operating permits, the Federal Energy Regulatory Commission (FERC) considers resource agency comments as they finalize Study Plans the owner of both facilities, Exelon Corporation, must conduct to provide sufficient information for permit decision making. 

Major issues include: determining enhanced upstream fish passage methods; mortality of fishes through turbines;  downstream passage for eels and other fishes; optimization of fish lift operations; water quality and flow conditions; bald eagle roost concentration areas; and possible presence of the Federally listed Maryland darter. 

As part of a unified team with Maryland, Pennsylvania, and Susquehanna River Basin Commission, the Service submitted comments on the final Study Plans on January 20, 2010. Proposed study costs total nearly $3.5 million.
