About Gronemeir Dam
The primary purpose of Gronemeir 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 Jerry Gronemeir (private). It impounds the Tr-middle Fabius near Monticello.
The dam stands 35 feet tall and stretches 235 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 29 acre-feet, and collects water from a drainage area of 129 square miles. Completed in 2004, 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. The most recent inspection on record was 11/01/2004. That was over 21 years ago.
At 35 feet, this dam is taller than 80% of dams nationwide.
