One of the biggest New York lakes, Keuka Lake, has 11,730 acres (47.5 km2) of surface area and a shoreline stretching 336 miles (541 kilometers).

9. Great Sacandaga Lake

The lake covers 20,650 acres (32.27 sq mi) and has a shoreline that stretches for 66 km. This lake has a maximum depth of 70 feet and holds a 22.920 billion cubic feet water volume.

As the planet heated around 10,000 to 12,000 years ago, glaciers started to melt and rip against rock, leaving behind silt, deposits, and ice fragments. As blocks of ice began to disintegrate, water flowed into the gouges in the earth, forming Lake George.

Honorable Mentions: More Large Lakes in New York

There are so many large and beautiful lakes in the state of New York that it’s hard to cover them all. We wanted to add a couple more to our already long list of massive lakes in the state.

Lake St. Francis

Lake St. Francis is a reservoir that covers 102,000 acres with a shoreline length of 540 miles. Two hydroelectric dames–Mosses-Saunders and Beauharnais–created it as an extension of the Lawrence River. Besides electricity generation, the lake boasts marinas, yacht clubs, and fishing. Multiple species–over 20 in all–inhabit the reservoir like walleye, steelhead, northern pike, muskie, lake trout, largemouth bass, smallmouth bass, king salmon, brook trout, rainbow trout, speckled trout, perch, catfish, whitefish, and crappie.

Cranberry Lake

While Cranberry Lake is the third largest lake in New York’s Adirondack Mountains, its remoteness is distinct, due to the fact it can only be accessed by boat. The lake covers 6975 acres with roughly 350 miles of shoreline. The lake is largely owned by the state, so is largely undeveloped. This creates a wonderful habitat for wild animals. There are a few remote campgrounds for adventurous outdoor folks, though reaching them involves quite a hike.
