Summary
Managed by the US Army, this Earth-type dam was completed in 1940 and serves primarily as a Fish and Wildlife Pond, with a normal storage capacity of 40 acre-feet. The dam has a structural height of 22 feet and a hydraulic height of 16 feet, with a spillway width of 40 feet for uncontrolled water release.
Situated on Tri-Little Greenleaf Creek, this picturesque pond covers a surface area of 4 acres and has a drainage area of 7 acres, providing recreational opportunities and habitat for local wildlife. Despite its low hazard potential, the dam undergoes regular inspections by the US Army, with the last inspection conducted in May 2002. With a moderate risk assessment score, the dam's condition assessment is currently marked as "Not Available," but it continues to serve its purpose of water storage and wildlife conservation in the region.
Water resource and climate enthusiasts will find Oknoname 101020 an intriguing example of federal water infrastructure, showcasing the intersection of nature conservation and human engineering. With its historical significance dating back to the 1940s and its ongoing role in supporting fish and wildlife populations, this dam serves as a vital component of the local ecosystem in Braggs, Oklahoma. The management and maintenance of this dam by the US Army ensure the safety and sustainability of this water resource for both recreational and environmental purposes.

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.
