Description

Consists of an earthen dam, a 25-ft-tall principal spillway to control normal flows, and a vegetated emergency spillway (200 ft wide in the right abutment) to protect the dam flows exceeding the 100-year flood. The principal spillway consists of a reservoir inlet structure, a concrete riser, and a 42-inch (in) diameter conduit and impact basin. The riser also has a 30-in-diameter crank operated circular sluice gate at the base of the riser for dewatering.
