Summary
Built in 1965, this Earth dam stands at a height of 15 feet and has a length of 710 feet, providing a storage capacity of 70 acre-feet. Despite its low hazard potential, it is regulated by the Oklahoma Water Resources Board and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations.
This dam serves a primary purpose that falls under the category of "Other," with a spillway width of 1 foot and a controlled spillway type. The risk assessment for Reherman Harold F has been rated as "Very High (1)" due to its location and potential impact on the surrounding area in case of failure. With only one outlet gate and a valve, the dam has not been rated for its current condition, but its inspection frequency is every 5 years, with the last inspection conducted in March 2002.
Overall, Reherman Harold F is a significant structure in the water resource management system of Oklahoma, providing vital storage and flood control benefits. Its history, design, and risk assessment highlight the importance of ongoing monitoring and maintenance to ensure the safety and effectiveness of this Earth dam for both water resource management and climate resilience in the region.

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.
