Scs-Criner Creek Site-020 Reservoir Report
Last Updated: December 13, 2025
SCS-Criner Creek Site-020, located in McClain County, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS in 1960 for flood risk reduction on TR Criner Creek.

Summary
With a height of 22 feet and a length of 960 feet, this dam has a storage capacity of 197 acre-feet and a maximum discharge of 700 cubic feet per second. The dam features a controlled spillway and a single valve outlet gate.
Although last inspected in 1980, this low-hazard dam is considered to have a very high risk potential, with a rating of 1 out of 5. The condition assessment is currently listed as "Not Rated" and the emergency action plan (EAP) status is unknown. Despite these uncertainties, the dam continues to serve its primary purpose of flood risk reduction in the region. While more recent information is needed to fully assess its current condition and risk level, SCS-Criner Creek Site-020 remains a key infrastructure for water resource management in the area.

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.
