Summary
Built in 1959, this dam stands at a height of 28 feet and spans a length of 1050 feet. It has a storage capacity of 270 acre-feet and a controlled spillway width of 1 foot, with a maximum discharge of 930 cubic feet per second. Despite its age, the dam has a low hazard potential and is currently not rated for its condition.
This dam on Spring Brook Creek is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement. Although it has not been inspected since 1980, it is deemed to have a very high risk assessment ranking, indicating the importance of monitoring and maintaining its structural integrity. With a single valve outlet gate, this dam serves as a crucial infrastructure for managing water resources in the area, particularly during periods of heavy rainfall and potential flooding events.
Under the oversight of the Natural Resources Conservation Service, SCS-Sandy Creek Site-31 plays a vital role in protecting the surrounding community from flood risks. The dam's strategic location in Ada, Oklahoma, and its design features contribute to its effectiveness in storing and controlling water flow. As water resource and climate enthusiasts, understanding and supporting the maintenance and upkeep of critical infrastructure like this dam is essential for ensuring the resilience of our communities 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.
