Summary
Completed in 1984, this dam stands at a height of 25 feet with a storage capacity of 100 acre-feet. The primary purpose of the dam is listed as 'Other' with a low hazard potential and a very high risk assessment rating. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement.
Despite being a privately owned structure, Wittrock Harold is fully regulated by the state and meets all necessary guidelines for safety and risk management. The dam features a controlled spillway and a single valve outlet gate for water release. Its condition is currently rated as 'Not Rated' with the last inspection conducted in June 2002. The risk assessment for Wittrock Harold is classified as very high, indicating the importance of proper monitoring and maintenance to ensure the safety of surrounding areas and water resources.
For water resource and climate enthusiasts interested in Wittrock Harold, this dam serves as a prime example of the vital role that privately owned structures play in water management and regulation. With a focus on risk management and safety, the dam is subject to rigorous state oversight and inspection protocols. Its location along the TR UNCLE JOHN CR river in Canadian, Oklahoma adds to the significance of its role in safeguarding the local environment and communities.

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.
