The Hamilton Street Dam, or Dam 7, was originally constructed of stone and wood crib and was eight feet high. The old dam was breached in 1979 and was replaced by a concrete dam. The present dam maintains a pool above it for boating and supplies water to the canal below, just as the old dam once did

The Hamilton Street Dam has a fish passage (fishladder). This is one of 3 fish ladders on the main stem of the Lehigh River that allow fish such as the American Shad to return to their spawning areas.
