Summary
2, located in Murray, Oklahoma, is a Federal-owned Earth dam primarily designed for recreational purposes. Standing at a height of 25 feet and stretching 90 feet in length, the dam provides a storage capacity of 24 acre-feet with a normal storage level of 20 acre-feet. Although the dam has a low hazard potential, its condition assessment is rated as poor, indicating a need for maintenance and improvement.
Despite its recreational focus, the dam's spillway type is uncontrolled and has a width of 15 feet, allowing for a maximum discharge of 500 cubic feet per second. While the dam's risk assessment is moderate, with a DSAC assigned date not yet available, it poses a potential risk to the surrounding area. The last inspection of Thedford Dam No. 2 was conducted in July 2015, with a frequency of inspections every 5 years, suggesting the need for regular monitoring and upkeep to ensure its safety and functionality for water resource and climate enthusiasts in the region.

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.
