Today, the Five Mile River watershed is home to several reservoirs and dams, including the Grumman Hill Reservoir and the Silvermine Dam. These reservoirs serve as major sources of drinking water for nearby communities. The river also supports recreational activities such as fishing and boating, as well as agricultural uses such as irrigation for local farms.
