Summary
The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a low hazard potential rating.
The dam features a controlled spillway and one outlet gate for water management. Although it has not been formally rated for condition assessment, its risk assessment is deemed very high, highlighting the importance of ongoing monitoring and maintenance. Despite not being under the jurisdiction of a federal agency, Crissmon Dam plays a crucial role in water resource management in the region, serving as a vital structure for regulating the flow of the Tri. to Little Deep Creek.
With its strategic location in the Tulsa District and proximity to the city of Hydro, Crissmon Dam represents a significant piece of infrastructure in the local water system. As climate change continues to impact water resources, the importance of maintaining and managing dams like Crissmon for flood control and water supply becomes increasingly critical for ensuring the resilience of communities and ecosystems in the face of changing environmental conditions.

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.
