About Rice Lake
The primary purpose of Rice Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Wisconsin Department Of Natural Resources (state). It impounds the Trib Whitewater Creek.
The dam stands 18 feet tall and stretches 200 feet across, creates a reservoir covering 137 acres, has a maximum storage capacity of 1,140 acre-feet, and collects water from a drainage area of 11 square miles. Completed in 1968, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 12/04/2020.
