NAPLES — The Songo Lock in Sebago Lake State Park is closed to boat traffic because of recent heavy rain and high water, the Maine Bureau of Parks and Lands announced this morning.

Built in 1830, the lock at Songo Lock State Historic Site is closed indefinitely because all flood-control gates have been opened to accommodate heavy water flow, said Park Manager Matt McGuire.

The gates will remain open until water levels in Brandy Pond and Long Lake drop more than two feet, McGuire said.

“People and fishermen who go down to the locks need to be very careful,” McGuire warned. “The water is swift and high.”

Opening the flood-control gates creates heavy cross currents and park officials want to preserve boater safety and limit shoreline damage, McGuire said.
