Summary

This dam, standing at a height of 11 feet and with a storage capacity of 90 acre-feet, serves the dual purposes of irrigation and recreation for the local community. With a normal storage capacity of 40 acre-feet, the dam covers a surface area of 9 acres and has a drainage area of 7 acres, making it a vital water resource in the region.

Despite its historical significance, Clark County 2 is rated as having a poor condition assessment, with a very high risk level of 1. The dam's hazard potential is considered low, but its risk assessment suggests a need for immediate attention and management measures. The last inspection was conducted in April 2012, indicating a gap in regular monitoring and maintenance practices. With the dam being state-regulated and subject to inspection, enforcement, and permitting by the Wisconsin Department of Natural Resources, it is essential for stakeholders to address the dam's deteriorating condition to ensure public safety and environmental sustainability.

In conclusion, Clark County 2 is a critical infrastructure for water management in Clark County, Wisconsin, serving multiple purposes while facing significant risk factors. Given the dam's poor condition assessment and high risk level, it is imperative for local authorities and stakeholders to prioritize its maintenance and management. With proper monitoring and timely interventions, this historic gravity dam can continue to support the community's needs for irrigation, recreation, and overall water resource management in the region.

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.
