When Lake Nockamixon was created by a dam, its waters covered the sites of several homes and a few businesses.

The small town of Tohickon, formerly called Stovertown, was located along the creek just upstream of the present dam. Much of the rest of the lake site was farmland, including farmhouses, barns, and other associated farm buildings. All of the buildings in the area now covered by the lake were demolished before the lake was filled. Many roads crossed the area now under the lake waters, and each road had a bridge where it crossed the Tohickon Creek. All of the bridges, except for the stone arch bridge at Tohickon village, were also demolished so they would not cause underwater hazards. The stone arch bridge is still there, under approximately 70 feet of water.
