Summary
The dam stands at a height of 25 feet with a hydraulic height of 23 feet and a length of 562 feet, providing a storage capacity of 125 acre-feet. It has a controlled spillway with a width of 1 foot and is equipped with a single valve outlet gate for water release.
Despite its low hazard potential and unassessed condition, Perry Ed No 1 poses a very high risk in terms of flood management, as indicated by a risk assessment ranking of 1. The dam falls under the jurisdiction of the Oklahoma Water Resources Board (OWRB) and is subject to state regulation, permitting, inspection, and enforcement. Although last inspected in August 2011 with a scheduled inspection frequency of 5 years, the condition assessment remains unrated, emphasizing the need for ongoing monitoring and maintenance to ensure the dam's structural integrity and safety.
With Markwayne Mullin (R) representing the area in the US Congress, Perry Ed No 1 serves as a critical infrastructure for flood control in the region. As water resource and climate enthusiasts, it is essential to recognize the significance of such structures in mitigating the impacts of extreme weather events and safeguarding communities against potential flood risks. Stay informed about the ongoing management and maintenance of Perry Ed No 1 to support sustainable water resource management and climate resilience efforts in 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.
