About Beckemeyer Lake Dam
The primary purpose of Beckemeyer Lake 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 Howard Beckemeyer (private). It impounds the Tr-hicklin Branch near Napoleon.
The dam stands 33 feet tall and stretches 375 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 123 acre-feet, and collects water from a drainage area of 140 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. The most recent inspection on record was 05/22/1980. That was over 46 years ago.
At 33 feet, this dam is taller than 76% of dams nationwide.
