About Larry Summers
The primary purpose of Larry Summers 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 Larry Summers (private). It impounds the Danaby Creek near Blythedale.
The dam stands 30 feet tall and stretches 277 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 16 acre-feet, and collects water from a drainage area of 32 square miles. Completed in 1996, the structure is 30 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
