Summary
Constructed in 1963 by the USDA NRCS, this dam serves the primary purpose of debris control and flood risk reduction along TR Rullands Coulee Creek. With a dam height of 32 feet and a hydraulic height of 20 feet, Coon Creek 24 has a storage capacity of 68 acre-feet and a maximum discharge rate of 275 cubic feet per second.
Despite its fair condition assessment and low hazard potential, Coon Creek 24 is subject to state regulation, inspection, and enforcement by the Wisconsin Department of Natural Resources. The dam features an uncontrolled spillway and covers a drainage area of 0.9 square miles, providing valuable flood protection to the surrounding area. While the risk assessment deems the dam's risk as moderate, ongoing maintenance and monitoring ensure its continued effectiveness in mitigating potential hazards and protecting the community.
For water resource and climate enthusiasts, Coon Creek 24 offers a fascinating example of engineered infrastructure designed to manage water flow and reduce flood risks in a rural setting. With its historical significance and ongoing regulatory oversight, this earth dam serves as a vital component of water resource management in Monroe, Wisconsin. As climate change continues to impact precipitation patterns and water levels, the importance of structures like Coon Creek 24 in safeguarding communities from potential flooding events becomes increasingly apparent.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
