About Oneida City Reservoir Dam
The primary purpose of Oneida City Reservoir Dam 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 Oneida (local government). It impounds the Florence Creek near Glenmore.
The dam stands 50 feet tall and stretches 378 feet across, creates a reservoir covering 88 acres, has a maximum storage capacity of 1,420 acre-feet, and collects water from a drainage area of 14 square miles. Completed in 1926, the structure is well-established, with more than 75 years of service.
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 09/22/2023.
At 50 feet, this dam is taller than 93% of dams nationwide.
