When the Erie Canal was redesigned and reconstructed to form the New York State Barge Canal in the early 20th century, the engineers made use of natural rivers and lakes where possible. The new barges were powered internally (by diesel or steam engines), so they could travel open water and against a current; the system no longer needed infrastructure for drawing vessels externally — i.e., drawpaths and draft animals. After it straightened Fish Creek on the east, the new canalway entered Oneida Lake at Sylvan Beach and exited west with the Oneida River at Brewerton.
