About Steinhoff Lake Dam
The primary purpose of Steinhoff Lake Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Everett Steinhoff (private). It impounds the Tr-weldon River near Trenton.
The dam stands 25 feet tall, creates a reservoir covering 4 acres, has a maximum storage capacity of 54 acre-feet, and collects water from a drainage area of 60 square miles. Completed in 1970, the structure is well into its service life at over 50 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.
