The Falls development is located in Stanly and Montgomery counties, North Carolina on the Yadkin River at river mile 234. Completed in 1919, the Falls development was the second of the Project developments to be built and is the most downstream of the four Yadkin Project developments. The Falls development consists of a dam, a gate controlled spillway, powerhouse and reservoir. Falls Reservoir has a normal full pool area of 204 acres and a drainage area of 4,190 square miles. The normal full pool elevation of Falls Reservoir is 332.8 feet (USGS datum).
The powerhouse is located immediately downstream of the intake structure between the gate controlled spillway section and river abutment. The powerhouse contains one vertical Francis turbine unit, and two Allis Chalmers propeller type turbine units (connected directly to generators). Two of the units have a licensed capacity of 9.97 MW and the other has a licensed capacity of 10.0 MW (for a total of 29.94 MW). The plant is automated and is operated remotely from Alcoa, Tennessee.
Like Tuckertown, the Falls development is operated as a run-of-river facility. Due to its limited ability to store water, during low streamflow periods, Falls Reservoir does not have the capacity to fulfill minimum downstream releases. Falls Reservoir is normally operated with a daily fluctuation of about 0 to 3 feet and there is no seasonal drawdown. The maximum drawdown capability at Falls is 10 feet.
