Conneaut Lake, the largest natural lake in Pennsylvania, was formed as a kettle lake. A large block of ice broke off the receding ice front and was surrounded by accumulating sediment. After the ice melted, the resulting depression was filled with water forming the lake. Water flows into Conneaut Lake through Inlet Run, a small stream to the north. Water exits through the Conneaut Outlet, a larger creek which flows to the south through the Conneaut Marsh, into French Creek, thus making it part of the Mississippi River drainage.
For the size of the lake, it has an oddly shallow depth in most areas. Most of the time it is around 20 to 25 feet deep.The Lake level was raised about 10 ft in the 1820s to permit the construction of canals. In the 1870s, canals were made obsolete by railroads, and the lake was returned to its natural elevation, though a dam remains for flood control.
The deep, cold waters of the lake allow it to stay frozen relatively late into the spring. This made Conneaut Lake a vital source of ice, prior to mechanical refrigeration.
