This Maine Lake Is Deeper Than the Height of a 30-Story Building
We have plenty of big, deep lakes in Maine, but the deepest one is actually deeper than the tallest building in our state is tall.
Thalassophobia is a strong fear of deep bodies of water, such as seas, oceans, or lakes—so if you have it, you may want to skip this trip to the lake. However, with over 6,000 lakes and ponds in our state, according to the University of Maine, there are still endless options for those who love being on the water.

So, how do we know which lake is the deepest in Maine? Did we go around and measure them all ourselves?
No, of course we didn’t. According to the Maine Geological Survey, conducted by the Department of Agriculture, Conservation and Forestry, Sebago Lake takes the crown as the deepest lake in our state.

Despite being second in surface area to Moosehead Lake, Sebago Lake reaches a depth of 316 feet at its lowest point, with a mean depth of 101 feet.
Located in southwestern Maine, 20 miles northwest of Portland and 50 miles southeast of the White Mountains, Sebago Lake spans the towns of Sebago, Casco, Naples, Raymond, Standish, and Windham.
At 316 feet deep, Sebago Lake is actually deeper than Maine’s tallest building, Saint Joseph’s Church in Biddeford, which stands at 235 feet.
While a proposed 30-story, 380-foot tower in Portland could change that, for now, the state’s deepest lake still beats its tallest building.

And there you have it — the deepest lake in our Pine Tree State is Sebago Lake, located in southwestern Maine.
