About Norman Lake Dam
The primary purpose of Norman Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Norman Downes Homes Association Mr. And Mrs. Hammett James Fisher (private). It impounds the Knox Branch near Duluth.
The dam stands 33 feet tall and stretches 520 feet across, creates a reservoir covering 14 acres, and has a maximum storage capacity of 240 acre-feet. Completed in 1950, 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 04/03/2013. That was 13 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 33 feet, this dam is taller than 78% of dams nationwide.
