About Tim Seim Dam
The primary purpose of Tim Seim 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 Tim Seim (private). It impounds the Tributary of the Iowa River near Tama.
The dam stands 25 feet tall and stretches 390 feet across, creates a reservoir covering 4 acres, and has a maximum storage capacity of 67 acre-feet. Completed in 2017, the structure is relatively new.
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.
