Lake Sebago Beach - Harriman State Park
Attention Lake Sebago Users
Hydrilla, a federally listed aquatic invasive species, was found in Lake Sebago in late 2022. If left unmanaged this aquatic plant can severely impact water quality and recreation. State Parks is implementing a 5-year treatment plan starting early June 2023. Yellow notice signs will be placed at public access points.

Trail Closures Along Victory Trail
Two existing Victory Trail connections near the northwest corner of Lake Sebago are temporarily closed. This is due to the ongoing construction as part of the rehabilitation of Lake Sebago's beach facility. These closures are expected to extend through the middle of 2027.
