About Spence/wilson
The primary purpose of Spence/wilson 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 Spence/wilson (private). It impounds the Tr-cat near Melbourne.
The dam stands 30 feet tall and stretches 465 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 100 acre-feet, and collects water from a drainage area of 262 square miles. Completed in 1997, the structure is 29 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 07/14/1997. That was over 28 years ago.
