Summary
Managed by the USDA NRCS, this earth-type dam stands at a height of 29 feet and has a length of 1400 feet, providing flood risk reduction for the surrounding area along TR-COON CREEK. Completed in 1972, the dam has a storage capacity of 555 acre-feet and a surface area of 17 acres, with a maximum discharge of 1300 cubic feet per second.
Despite being classified as having a low hazard potential, SCS-Sandy Creek Site-19 is considered to be at very high risk due to its location and purpose. The dam is equipped with a controlled spillway and a single valve outlet gate for water release. Although the condition of the dam is currently not rated, it undergoes inspections every 5 years to ensure its structural integrity and effectiveness in flood risk reduction. Additionally, the site does not have an emergency action plan prepared, which may be a concern for potential risk management in the event of a disaster.
Overall, SCS-Sandy Creek Site-19 serves as a vital infrastructure for managing flood risks in the region, with a focus on protecting the surrounding community from potential inundation. As a state-regulated structure with a history dating back to the early 1970s, the dam continues to play a crucial role in water resource management and climate resilience efforts in Oklahoma. While the site faces some risk factors, regular inspections and potential risk management measures can help ensure the continued safety and effectiveness of this essential water management infrastructure.

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.
