Summary
Completed in 1983 for the primary purpose of flood risk reduction, this structure stands at a height of 40 feet with a hydraulic height of 36 feet. With a storage capacity of 160 acre-feet and a surface area of 22 acres, it plays a crucial role in mitigating potential flooding in the area.
Managed by the Oklahoma Water Resources Board and regulated by the state, Alvin R & Leigh R has a low hazard potential and has not been rated for its current condition. Despite its low hazard potential, the risk assessment for this dam is classified as very high, indicating the importance of regular inspections and maintenance. The last inspection was conducted in August 2010, with an inspection frequency of every 5 years.
With one valve outlet gate and a controlled spillway type, Alvin R & Leigh R is equipped to handle water discharge efficiently. The dam is in the jurisdiction of the Tulsa District of the US Army Corps of Engineers and is overseen by state regulatory agencies. As a key component in flood risk reduction in the area, this dam serves as a vital resource for water management and climate resilience efforts in Canadian, Oklahoma.

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.
