Repairs to the Adam T. Bower Memorial Inflatable Dam on the Susquehanna River will be postponed until 2022. This seasonal dam creates Lake Augusta, the 3,000-acre body of water located at the main confluence of the Susquehanna River. The repair project began in late August 2021 and was on schedule for completion 2021 until river conditions required the work stoppage. Tropical storms Henri and Ida contributed to higher than normal water levels on the Susquehanna River. Subsequent flooding delayed the start of the repairs and have made it unsafe to complete the work in fall 2021.

The dam will not be able to operate without installing the new bag, resulting in the lake remaining at its winter levels until the repairs can be made. Additionally, the parks marina and boat ramp docks cannot be installed without the dam functioning normally.

We are aware that this project news is disappointing to our many park visitors and Lake Augusta users. It is the department’s commitment to complete the remaining work and resume normal operations as quickly and safely as is possible. Work is projected to resume in 2022 when river levels are lower and weather conditions are more favorable, with July being the likely beginning timeframe. If site and weather conditions permit work, a partial boating season may occur after repair completion. 

Warning: The spotted lanternfly has invaded our area. This invasive insect could cause serious harm to Pennsylvania’s resources, businesses, and economy. LOOK BEFORE YOU LEAVE! Help us stop the spread of these unwelcome hitchhikers. Inspect your vehicle, camper, tent, gear, etc. before you leave the park and destroy any lanternflies you find.
