Summary
Built in 2006 by designer James Willey, this earth dam serves multiple purposes including fire protection, stock watering, and small fish pond management. The dam stands at 28 feet tall with a hydraulic height of 14 feet, providing a storage capacity of 228 acre-feet and covering a surface area of 21 acres.
Despite its low hazard potential, Harris No.2 is currently in poor condition, as assessed in June 2021. The dam has a drainage area of 3.18 square miles and can discharge a maximum of 3356 cubic feet per second through its uncontrolled spillway. The dam is equipped with a single valve outlet gate and is regularly inspected every 5 years to ensure its structural integrity and safety.
While the risk assessment for Harris No.2 indicates a moderate level of risk, there are currently no risk management measures in place. With Liz Cheney representing the area in Congress, stakeholders and water resource enthusiasts are encouraged to monitor the condition of this dam and advocate for necessary repairs and improvements to mitigate potential risks and ensure the continued safety of the surrounding community and ecosystem.

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.
