Important Watershed Updates

Due to playground renovations at the Triadelphia picnic and playground areas, a section of the parking lot will be closed until further notice. The rest of Triadelphia recreational area will remain open (fishing pier and shoreline fishing areas).

The sediment removal project on Triadelphia Reservoir is scheduled from Thursday, May 18 through Tuesday, October 31, 2023. During this period, all the boat ramps on Triadelphia Reservoir will be closed, and no boating will be allowed. To ensure public safety, the recreational areas at Greenbridge and Pig Tail will be closed.
