About Twin-rush Creek Dam No. 2
The primary purpose of Twin-rush Creek Dam No. 2 is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by City Of Salem (local government). It impounds the Rinkers Creek near Rush Creek Valley.
The dam stands 65 feet tall and stretches 1,540 feet across, creates a reservoir covering 210 acres, has a maximum storage capacity of 10,650 acre-feet, and collects water from a drainage area of 9 square miles. Completed in 1969, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 01/19/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.
At 65 feet, this dam is taller than 96% of all dams in the United States.
