About Jubilee Lake
The primary purpose of Jubilee Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Oregon Department Of Fish And Wildlife (state). It impounds the Mottet Creek near Tro.
The dam stands 50 feet tall and stretches 350 feet across, creates a reservoir covering 98 acres, has a maximum storage capacity of 1,579 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1967, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 08/26/2021.
At 50 feet, this dam is taller than 93% of dams nationwide.
