Summary
The dam, primarily constructed of earth, stands at a height of 27 feet and has a storage capacity of 20 acre-feet. Situated on Cuddy Creek in the Tulsa District, Harper serves as a crucial component for managing water resources in the region.
Despite being privately owned and not regulated by the state, Harper's hazard potential is rated as low, with a moderate risk assessment score of 3. The dam, with an uncontrolled spillway type, has not been rated for its condition assessment. While the emergency action plan status is unknown, Harper's risk management measures are yet to be identified, highlighting opportunities for further evaluation and improvement in ensuring the safety and effectiveness of this water resource.
For water resource and climate enthusiasts, Harper presents an intriguing case study in private water management and the potential for enhancing risk assessment and emergency preparedness. With its unique location and design features, Harper offers a glimpse into the complexities of managing water resources in rural settings and the importance of proactive risk management strategies in safeguarding infrastructure and surrounding communities from potential hazards.

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.
