Keoka Lake covers 467 acres and is located in Waterford, Oxford County, Maine (see The Maine Atlas and Gazetteer map 10 D4). Public access is via the boat launch located right next to Route 35. Parking is on the road shoulder. However, beware that it may be next to impossible to leave a vehicle if the road shoulder is filled with plowed snow, as is the case for me today. One obvious alternative is to park your vehicle next door, on the lot in front of the Waterford Historical Society building. I see no signs forbidding this practice, but do not know if it is frowned upon.
The public access point to Pettingill Pond is unobtrusive and unmarked. No parking is allowed in this vicinity.
Pettingill Pond covers 36 acres and is located across from Seacoast Adventure in Windham, Cumberland County, Maine (see The Maine Atlas and Gazetteer map 5 C2). The public access to this body of water can be tricky to find under the snow in the winter. While driving on Route 302 in Windham (direction Raymond and Naples, i.e., north), turn right at the light on Anglers Road just past Bob’s Seafood Restaurant, go down that ruddy road for about 0.4 miles and look for house number 48. The small, unmarked public access point will be to your left immediately past that house (and across from house #51). You have gone too far if you reach Mud Pond Road. Keep in mind that Anglers Road is narrow, potholed, and trafficky, and no vehicles are allowed to park on it or by the public access. The only readily-available place to leave your car is by Route 302.
Sand Pond is a 61-acre body of water located in Baldwin, Cumberland County, Maine (see The Maine Atlas and Gazetteer map 4 D4). The pond is accessible via the public boat launch located at its southern tip by the municipal beach, next to Sand Pond Road off Route 107 (Bridgton Road). Plenty of parking space is available across from the launch.
