Summary

Completed in 1940, this earth dam stands at 15 feet high with a primary purpose of water supply. With a maximum storage capacity of 60 acre-feet and a normal storage of 26 acre-feet, Porum serves as a vital water resource in the region.

Despite its age, Porum has a low hazard potential and has not been rated for its condition. Inspected every 5 years, the dam is equipped with a controlled spillway and a single valve outlet gate. The risk assessment for Porum indicates a very high risk level (1), highlighting the importance of proper risk management measures to ensure the safety and functionality of this essential water infrastructure.

For water resource and climate enthusiasts, Porum presents an intriguing case study of a historic dam in Oklahoma with significant water supply capabilities. As a key structure in the region, understanding and managing the risks associated with Porum is crucial for ensuring the continued availability of water resources for the local community. The data provided offers a glimpse into the technical specifications and regulatory oversight of this important dam, sparking further interest in the intersection of water management and climate resilience.

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.
