About G.talmage Structure Dam
The primary purpose of G.talmage Structure Dam 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 Gerald H.talmage (private). It impounds the Tr-zounds Creek & Grand River near Alanthus Grove.
The dam stands 31 feet tall and stretches 450 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 36 acre-feet, and collects water from a drainage area of 377 square miles. Completed in 1977, the structure is 49 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.
