About Sebago Lake
Sebago Lake is the second-largest lake in Maine and the deepest at 316 feet — its bottom is well below sea level. It covers about 45 square miles in Cumberland County half an hour from Portland, and it has supplied the city's drinking water since 1869, which is why the water is so clean.
Sebago Lake State Park, Naples at the Songo River locks, Raymond, Standish and Windham make up the shore. Landlocked salmon were first described from this lake, and the Songo River still carries boats through to Long Lake.

Sebago Lake depth chart, in wood
This is a Sebago Lake depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 53 ft, 105 ft, 158 ft, 211 ft, 264 ft and deeper, down to the deepest hole at about 316 ft. The lake covers about 47.1 square miles, and 1052 shore roads are engraved around it. The shape of the bottom is the real one from published soundings, so anglers recognise their drop-offs and points.
A Sebago Lake map for the wall — or a gift
Most of these go to a cabin wall, a lake house entry, or a home office; a lot are gifts — the family that has been on Sebago Lake for three generations, the retirement move, the first boat. The 12-inch is the desk-and-shelf size; the 24- and 30-inch boards read across a room. Add a line under the title and star your place on the shore, and it becomes the map of your Sebago Lake.
Sebago Lake map — the details
How big is the map?
Four sizes: 12, 17, 24 and 30 inches on the long side, from $149. Every size is cut from the same depth data of Sebago Lake; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Sebago Lake is cut layer by layer from published bathymetric soundings — each layer of birch is a depth contour, so the shape of the bottom is the real one, not decorative.
Can I add my own place on it?
Yes. At checkout you can add a line under the title (a family name, a cabin name, a year) and star the spot on the shore that matters to you.
How long does it take?
Made to order in Waterford, Pennsylvania and shipped in 7–10 days; shipping is free in the lower 48.
Can you make a lake that isn't listed?
Any lake in the United States — we hold depth data for 104,419 of them. Search for yours; if it isn't built yet we build it when you order.
