Summary
Built in 1961 by USDA NRCS, the dam stands at a height of 21 feet and has a length of 1400 feet, providing flood risk reduction along TR-Whitegrass Creek. It has a maximum storage capacity of 520 acre-feet and a normal storage of 36 acre-feet, with a surface area of 14 acres.
Despite being classified with a low hazard potential, the dam is considered to have a very high risk level, highlighting the importance of regular inspections and maintenance. The dam features a controlled spillway and a single valve outlet gate. While the condition assessment is listed as 'Not Rated', the dam has not been inspected since January 1980, with an inspection frequency of 5 years. The regulatory oversight is maintained by the Oklahoma Water Resources Board (OWRB), ensuring compliance with state jurisdiction and permitting requirements.
For water resource and climate enthusiasts, SCS-Whitegrass-Waterhole Cr Site-3 offers an intriguing case study in flood risk reduction infrastructure. With its historical significance dating back to the 1960s, the dam's design and construction by the USDA NRCS reflect a commitment to sustainable water management practices. As climate change continues to impact water resources, understanding the maintenance and management of such critical infrastructure is vital for ensuring the resilience of communities and ecosystems in the face of evolving environmental challenges.

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.
