Maine state parks and historic sites are beginning to open for the season. Officials with the Maine Bureau of Parks and Lands, under the Maine Department of Conservation, announced the following updates about several parks around the state.

Sebago Lake State Park in Casco opened Friday, April 29, according to park manager Andy Haskell. All the sites at Witch Cove are open — about 125 sites — and the shower buildings are also open.

Campers can choose a site and self-register, Haskell said. Formal campground reservations for Sebago start until Monday, May 23.

Off-season rates will be in effect through May 22. They are:

• Maine residents, $10 per night with no hook-ups; $15 a night with water and electricity;

• Nonresidents, $18 per night with no hook-ups; $25 a night with water and electricity.

Lake St. George State Park in Liberty is also available for camping, according to park manager Leland Griffin. About 20 campsites are open thus far; the remaining campsites haven’t yet dried out. Rates are the same for Maine residents and nonresidents as those at Sebago, though Lake St. George doesn’t have hook-ups,

Ice on the lake went out April 19, and anglers are “doing quite well,” said Griffin. While he hadn’t heard of any trout being caught, “they’re getting some nice salmon.”

At Ferry Beach State Park in Saco, park manager Bob Crocker said the park is open, though construction is taking place on Bayview Road, which runs in front of the park’s access road. Bayview Road is reduced to a one-lane, gravel road with flaggers. The construction crew has been working some Saturdays.

And, floats are in the water at Warren Island State Park, located off Lincolnville and Islesboro in Penobscot Bay. The park is one of two island facilities managed by BPL.

As of May 3, floats will be installed at Holbrook Island Sanctuary in Brooksville.
