About Sagamore Lake Dam
The primary purpose of Sagamore Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Lalumondiere, Lindell (private).
The dam stands 44 feet tall and stretches 400 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 142 acre-feet, and collects water from a drainage area of 179 square miles. Completed in 1980, the structure is 46 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. The most recent inspection on record was 01/28/1992. That was 34 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 44 feet, this dam is taller than 90% of dams nationwide.
