Summary
Built in 1980 by the USDA NRCS, this dam on TR-Walnut Creek serves multiple purposes, including flood control and water resource management. With a height of 36 feet and a length of 1450 feet, it has a storage capacity of 760 acre-feet and a drainage area of 1.4 square miles.
The dam's spillway is of the controlled type, with a width of 1 foot, and it has one outlet gate for water release. Despite its low hazard potential, the risk assessment for this dam is rated as very high (1), indicating the importance of regular inspections and maintenance. The condition assessment is currently listed as "Not Rated," with the last inspection date dating back to January 1, 1980. Overall, the SCS-Okfuskee Tributaries Site-W03 plays a crucial role in water management in the region and requires ongoing monitoring to ensure its safety and efficiency.
Located in a picturesque setting near the city of Mason, this dam is a key feature of the local water infrastructure and contributes to the conservation efforts in the area. Managed by the OWRB and with oversight from the state regulatory agency, this dam represents a collaborative effort to protect the environment and ensure sustainable water practices. Water resource and climate enthusiasts will appreciate the vital role that the SCS-Okfuskee Tributaries Site-W03 plays in maintaining the ecological balance and resilience of the surrounding watershed.

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.
