Summary
27, is a state-regulated earth dam located in Cloud Chief, Washita County, Oklahoma. Built in 1959 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along TR-Cavalry Creek. With a height of 24 feet and a length of 800 feet, the dam has a storage capacity of 216 acre-feet and a maximum discharge of 1210 cubic feet per second. Despite being classified as low hazard potential, the risk assessment for this site is rated as very high, indicating the importance of proper monitoring and maintenance.
The dam features a controlled spillway with a width of 1 foot and an outlet gate for regulation. While the condition assessment is currently not rated, the last inspection date recorded was in 1980, with a scheduled inspection frequency of 5 years. Although no emergency action plan (EAP) or inundation maps have been reported, the dam is under state jurisdiction and is subject to inspection, enforcement, and permitting by the Oklahoma Water Resources Board (OWRB). With a risk management measure not specified and no assigned DSAC date, ongoing monitoring and risk assessment are crucial for ensuring the safety and effectiveness of this flood control structure in the face of changing climate patterns and water resource challenges.

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.
