In 1975, the superstructure of the flood control dam was removed and the dam lowered by four feet. The dam that we know today was kept in place to create a decorative waterfall and maintain a “reflecting pool” of water upstream of the bridge.
Unfortunately, this dam currently contributes to flooding by holding back silt deposits. It undermines the ability of aquatic organisms to move upstream. It also prevents recreational use of the river because it generates dangerous currents.
