Summary
Built in 1970 by the USDA NRCS, this dam stands at a height of 25 feet and serves primarily as a water supply structure. Its maximum storage capacity is 95 acre-feet with a normal storage level of 70 acre-feet. The dam has a controlled spillway and a valve outlet gate to manage water release and flow.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last assessment conducted in May 2011. Despite being classified as having a low hazard potential, Peterson S is rated as having a very high risk due to its condition not being assessed. It is important for water resource and climate enthusiasts to monitor the risk level and management measures associated with this dam to ensure its continued safety and functionality.
With its proximity to the TR-Panther Creek and its vital role in water supply, Peterson S offers a fascinating case study for those interested in the intersection of water resource management and climate resilience. The dam's design and operational features, combined with its risk assessment and regulatory oversight, highlight the complex challenges faced in maintaining and safeguarding critical infrastructure in the face of changing environmental conditions.

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.
