Summary
The dam stands at a height of 34 feet with a hydraulic height of 30 feet and a structural height of 34 feet. It has a length of 940 feet and a storage capacity of 308 acre-feet, providing essential flood protection for the surrounding area.
Managed by the Natural Resources Conservation Service, this dam features a controlled spillway with a width of 1 foot and a single valve outlet gate. Despite being assessed as "Not Rated" in terms of condition, the hazard potential is categorized as low, with a very high risk assessment rating of 1. While the last inspection was conducted in 1980, the dam is subject to regular inspections every 5 years to ensure its continued safety and effectiveness in flood control. The site's risk management measures and emergency action plan status are currently unspecified.
Water resource and climate enthusiasts interested in the infrastructure supporting flood risk reduction in Oklahoma will find SCS-Sandstone Creek Site-020 to be a significant asset in the region. With its strategic location along the TR-Sandstone Creek and its vital role in protecting the local community from potential flooding events, this Earth dam serves as a critical component of the state's water management system. As efforts continue to maintain and monitor the dam's condition and functionality, its impact on water resources and climate resilience remains a key focus for stakeholders and regulators in the 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.
