About Winona Reservoir
The primary purpose of Winona Reservoir 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 Usda Fs (federal).
The dam stands 41 feet tall and stretches 400 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 200 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1959, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 11/15/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
At 41 feet, this dam is taller than 88% of dams nationwide.
