Summary

Managed by the local government, the dam stands at a hydraulic height of 23 feet with a length of 821 feet, providing a NID storage of 301.8 acre-feet. With a high hazard potential, the dam is regulated, inspected, and enforced by the Oklahoma Water Resources Board to ensure public safety and environmental protection.

Despite its significant role in mitigating flood risks in the area, Little River Park Dam has not been rated for its condition assessment. The dam's emergency action plan status, inundation maps, and risk assessment measures are also undisclosed. While the dam's operational and maintenance activities are not under the purview of any federal agency, its state-regulated status signifies a commitment to upholding safety standards and compliance with regulatory guidelines.

Water resource and climate enthusiasts monitoring the Little River Park Dam can appreciate its strategic location within the Cleveland County landscape, safeguarding the community against potential flooding events. As the dam continues to play a vital role in flood risk reduction, ongoing assessments and management measures are essential to ensure its resilience and effectiveness in protecting the surrounding environment and inhabitants from water-related hazards.

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.
