Summary
This earth dam serves multiple purposes and has a storage capacity of 90 acre-feet, with a normal storage level of 45 acre-feet. The dam regulates the flow of water from the tributary to Little Deep Creek and features a controlled spillway with a width of 1 foot.
Managed by a private entity, Creach Dam is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance. Despite being rated as having a low hazard potential, the dam is considered to have a very high risk level, indicating the need for vigilant risk management measures. The dam's condition is currently not rated, and the last inspection was conducted in July 2011.
Water resource and climate enthusiasts interested in Creach Dam will find it to be a captivating structure with a unique history and purpose. Its location in Custer County, Oklahoma, and its role in water management make it a significant feature in the region's hydrological landscape. With ongoing state oversight and a focus on risk management, the dam continues to play a crucial role in ensuring water safety and security for the surrounding area.

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.
