The Cayuga-Seneca Canal is a waterway in New York that connects Cayuga Lake and Seneca Lake, two of the largest lakes in the Finger Lakes region. Completed in 1828, the canal is part of the larger New York State Canal System and plays a crucial role in facilitating navigation and transportation in the area. The canal stretches approximately 16 miles and features several locks that help boats navigate the elevation changes between the lakes. It supports recreational activities such as boating and fishing, contributing to the local economy and tourism in the surrounding communities.
