Lake Tonawanda was a prehistoric lake that existed approximately 10,000 years ago at the end of the last ice age, in Western New York, United States.[1]
The lake existed on the southern (upper) side of the
Lockport, New York
.
The lake evaporated when the waters of Lake Erie dropped below the level of the feeder streams to the lake. Subsequently Lake Erie drained over the escarpment entirely through Niagara Falls, which marks roughly the western terminus of the former lake bed.
The remains of the previous falls, which rivaled Niagara Falls in grandeur, can be seen along the escarpment. The sinking of homes in the lakebed has been an ongoing problem in communities such as Amherst, New York.
