About Blue Marsh Lake

Blue Marsh Lake is number 86 on the LakePA 100: a 1,121-acre reservoir in Berks County, in our Southeast region. You may also see it called Blue Marsh Reservoir. The acreage comes from the Corps of Engineers lake page. It counts toward the Big Water tier, which means wind and long crossings can matter on a paddle here. There is no motor limit, so expect powerboats and their wakes. That rule is as listed by the Fish and Boat Commission's access data. There are three put-ins on our list for this lake, among them Sheidy Road access area, Dry Brooks Boat Launch and State Hill Boat Launch. Sheidy Road access area has a paved ramp, a dock and parking listed as 10 spaces or more. At Fish and Boat Commission and state park launches your boat needs a Pennsylvania registration or a PFBC or State Parks launch permit. It is held back by a dam: stay well clear of the dam, the spillway and the outlet structures. Logging it moves you toward the Southeast region milestone. As the crow flies, the closest put-in is about 6 miles from Reading. Before you go, check posted signs, the weather and the operator's notices.

Check the weather, posted signs and the operator's notices before you launch. Stay well away from dams, spillways and outlet structures. You paddle at your own risk.
