Sebago Lake is Maine's largest lake and the primary water supply for the Portland metropolitan area. It extends across six towns — Naples, Casco, Sebago, Raymond, Standish, and Windham — covering roughly 28,771 acres in Oxford and Cumberland counties. The lake's depth reaches 316 feet at its deepest point, which contributes to its exceptionally clear water and its reputation among anglers for landlocked salmon and lake trout. Sebago Lake State Park, located in Naples and Casco along the northeastern shore, draws visitors to its sandy beaches and boat launch facilities.
Waterfront properties on Sebago Lake vary considerably by location. The eastern and northeastern shores in Naples, Casco, and Raymond are more accessible from Route 302 and tend to see higher seasonal activity, particularly around Jordan Bay in Raymond and the State Park area. The western and southern shores in Sebago and Standish are quieter and more rural in character, with properties that often sit on larger parcels. St. Joseph's College occupies a stretch of the Standish shoreline near White's Bridge. For a full picture of the lake, see the Sebago Lake guide or explore the individual town pages for Sebago, Casco, and Naples.
