The Sing Sing Yacht Club lengthened its clubhouse in the 1890s. Access to the club was by a path from present day North Water Street (not shown) to a narrow strip of club property south of the tracks (shown), thence over the tracks on a planked foot-path, to a foot bridge from shore to the boathouse.

The Sing Sing Electric Light Company established a powerhouse on Upper Dock. The Ossining Yacht Club built a clubhouse on a float south of Peter Smith Dock.
