Spring Creek
Spring Creek is a gravity dam located in Portage County, Wisconsin, built in 1854. It carries a High hazard potential classification and has a fair condition assessment.
About Spring Creek
The primary purpose of Spring Creek is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Spring Creek Land And Power, Llc (private). It impounds the Spring Creek.
The dam stands 13 feet tall and stretches 60 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 120 acre-feet, and collects water from a drainage area of 17 square miles. Completed in 1854, the structure is one of the older dams in the region, with over a century and a half 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 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 06/14/2015. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

The Wisconsin dam safety program can provide more specific information about emergency planning for this structure.
