About Root Dam

The primary purpose of Root Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by J. W. Davis (private). It impounds the Sand Creek near Tallmadge.

The dam stands 14 feet tall and stretches 500 feet across, has a maximum storage capacity of 60 acre-feet, and collects water from a drainage area of 49 square miles. Completed in 1860, the structure is one of the older dams in the region, with over a century and a half of service.

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 11/14/1979. That was over 46 years ago.
