Summary

With a height of 27 feet and a storage capacity of 70 acre-feet, this dam serves a primary purpose of "other." The structure is regulated by the Oklahoma Water Resources Board and has state permitting, inspection, and enforcement in place.

Despite being classified as a low hazard potential, Leedy At poses a very high risk due to its condition assessment being "not rated." The dam features a controlled spillway and a single valve outlet gate. While the last inspection was conducted in 2010, the structure has an inspection frequency of 5 years. The risk management measures and emergency action plan status for Leedy At remain unclear.

For water resource and climate enthusiasts, Leedy At presents an intriguing case study in dam management and risk assessment. The structure's location on the TR-CANADIAN RIVER and its significance in the local watershed make it a focal point for understanding the interplay between water infrastructure, regulatory oversight, and emergency preparedness. The data provided offers a snapshot of the complexities involved in maintaining and monitoring dams for both water resource security and public safety.

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.
