Important Watershed Updates

Effective January 5, 2023, 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).

Effective December 1, 2022, all boat ramps and boating activities are closed through March 14, 2023.

A sediment removal project on Triadelphia Reservoir is anticipated to begin in Spring/Summer 2023. During that time, all boat ramps will be closed and no boating will be allowed. Additionally, the Greenbridge and Pig Tail recreational areas will be closed to ensure public safety due to the construction activity.
