About Harold Kelly Dam
The primary purpose of Harold Kelly 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 Harold Kelly (private). It impounds the Tr-medicine near Laredo.
The dam stands 30 feet tall and stretches 249 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 62 acre-feet, and collects water from a drainage area of 173 square miles. Completed in 1995, the structure is 31 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 09/26/1995. That was over 30 years ago.
