Summary

Completed in 1944, this earth dam stands at a height of 11 feet and has a hydraulic height of 10 feet, with a structural height of 13 feet. The dam spans a length of 285 feet and has a normal storage capacity of 152 acre-feet, serving as a vital resource for the conservation of aquatic life in the area.

Situated on the Waupee Creek, the dam plays a crucial role in managing water resources and providing habitat for various wildlife species. With a significant hazard potential and a moderate risk assessment rating, the dam's condition remains unrated, highlighting the need for regular inspections and maintenance. The dam's spillway, which is uncontrolled and 30 feet wide, helps regulate water flow and prevent potential flooding downstream, showcasing the importance of this structure in both water management and environmental conservation efforts.

As a key element in the local ecosystem, the Waupee Dam not only serves as a water resource infrastructure but also contributes to the preservation of fish and wildlife populations in the region. With its historical significance dating back to the mid-20th century, the dam continues to be a vital component in maintaining the delicate balance of the surrounding environment, making it a noteworthy site for water resource and climate enthusiasts to explore and appreciate.

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.
