About Tilden
The primary purpose of Tilden is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Williams, Stephen (private). It impounds the Duncan Creek.
The dam stands 16 feet tall and stretches 115 feet across, creates a reservoir covering 61 acres, has a maximum storage capacity of 250 acre-feet, and collects water from a drainage area of 110 square miles. Completed in 1886, the structure is over a century 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 05/21/2009. That was over 17 years ago.
