Dam profile
NID height · 26 ft26 ft tall and 309 ft long, taller than 55% of U.S. dams with a recorded height. Height is drawn to scale against a two-story house, about 25 ft; the profile is a generic embankment section and the water level is illustrative.
About Holt Dam
The primary purpose of Holt 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 Gene Holt (private). It impounds the Tr-north Wyaconda near Lagrange.
The dam stands 26 feet tall and stretches 309 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 24 acre-feet, and collects water from a drainage area of 38 square miles. Completed in 1991, the structure is 35 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.
