Summary

The dam stands at a height of 29 feet with a length of 1030 feet, providing a storage capacity of 317 acre-feet and a maximum discharge rate of 450 cubic feet per second. Despite its low hazard potential, the dam has not undergone a condition assessment and is currently rated as "Not Rated" in terms of its condition assessment.

The dam features a controlled spillway with a width of 1 foot and an outlet gate equipped with a single valve. It is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement. The risk assessment for SCS-Canyon View Site-1 indicates a very high risk level, highlighting the importance of regular monitoring and maintenance to ensure the safety and effectiveness of the flood risk reduction infrastructure. With its strategic location in Canadian County and contributions to water resource management in the region, this dam serves as a crucial asset for mitigating flood risks and protecting the surrounding communities from potential water-related disasters.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
