Summary

The dam stands at a height of 9 feet with a structural height of 9 feet and a length of 57 feet, creating a storage capacity of 430 acre-feet. Situated on the Casey Creek, the dam regulates the flow of water and provides a surface area of 99 acres for recreational activities.

Managed by the Wisconsin Department of Natural Resources (WIDNR), Conroy Ford is state-regulated with permitting, inspection, and enforcement mechanisms in place to ensure its safety and functionality. Despite its fair condition assessment and low hazard potential, a risk assessment has classified the dam as having a very high risk, warranting attention to potential vulnerabilities. With a controlled spillway and a maximum discharge capacity of 450 cubic feet per second, the dam plays a crucial role in managing water resources in the area while offering opportunities for outdoor recreation.

In the care of local government ownership, Conroy Ford serves as a vital infrastructure for both water resource management and recreational purposes in Washburn County, Wisconsin. As climate change continues to impact water availability and quality, the proper maintenance and monitoring of dams like Conroy Ford are essential for safeguarding the surrounding environment and communities that depend on this important water resource.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
