An Aegis article (2018-09-13) reported that Cecil County experienced some minor flooding along its Susquehanna River shore after 14 of the dam’s 50 floodgates were opened at the Conowingo Dam to alleviate rising waters behind the dam. The Port Deposit area saw most of the flooding effects. The current water release is not associated with Hurricane Florence but both the dam’s owner, Exelon Generation, and state officials are monitoring the storm’s track carefully. At this point, Exelon does not believe Florence will have an effect on the dam or its reservoir. From the article:
“We’re in contact with all of our local communities and emergency responders,” Deena O’Brien, a spokesperson for the dam’s parent company, Exelon Generation, said Wednesday afternoon. …
Weather conditions that are “most impactful to” Conowingo Dam, which spans the Susquehanna between Cecil and Harford counties, happen in central Pennsylvania, O’Brien said.
“The hurricane is not expected to have any impact in central Pennsylvania, thank goodness, so we’re not expecting a significant event with the hurricane,” she said.
The article also discussed actions that Maryland Governor Larry Hogan and state officials are taking in response to Florence’s potential threat and Exelon’s efforts to remove debris that comes down the Susquehanna. Debris that is not captured by Exelon is released into the Chesapeake Bay and its tributaries where it can create public safety and environmental hazards. The article noted that an unusually heavy debris release in July after record rainfall prompted both state and local government concern.
The article provided a hotline number that people can call to get information on floodgate openings: 1.877.457.2525. The hotline report is updated every eight hours.
