Summary
Built in 1945, this Earth dam stands at a height of 37 feet and has a length of 1500 feet, providing a storage capacity of 550 acre-feet. The dam serves a primary purpose classified as "Other" and is regulated by the Oklahoma Water Resources Board.
With a hazard potential rated as "Low" and a condition assessment listed as "Not Rated," Mcpherson Pg has not undergone recent inspections or condition assessments. Despite this, the risk assessment for the dam is categorized as "Very High (1)," indicating the importance of monitoring and maintaining the structure to ensure public safety and water resource sustainability. The dam features a controlled spillway type and is equipped with a valve outlet gate for water release.
While Mcpherson Pg currently poses a low hazard potential, its very high risk assessment underscores the need for ongoing monitoring and maintenance. As a crucial component of water resource management along the TR-CANADIAN RIVER, this Earth dam plays a vital role in flood control and water storage within the region. With its location in McClain County, Oklahoma, and under the jurisdiction of the OWRB, it is essential to prioritize the safety and integrity of Mcpherson Pg to mitigate potential risks and ensure long-term climate resilience.

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.
