About Christopher Erb
The primary purpose of Christopher Erb is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Christopher Erb (private). It impounds the Tr-river Aux Vase near Valley View.
The dam stands 32 feet tall and stretches 441 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 72 acre-feet, and collects water from a drainage area of 153 square miles. Completed in 1996, the structure is 30 years old.
