Water Tunnels
Tunnels increased power. Here water from the inner basin, located off to your right, flowed through a series of underground passages. With openings smaller at the downstream end - like a nozzle on a garden hose - these tunnels increased the water's flow. This increased pressure created more waterpower for the factories.
As you continue along the trail, look for evidence of the river wall and the head gates - other features of this elaborate waterpower system, first built around 1848.
Marker can be reached from Shenandoah Street (Business U.S. 340), on the right when traveling east.
