Summary
1, located in Stephens County, Oklahoma, is a private water resource regulated by the Oklahoma Water Resources Board. The pond, designed by NRCS, serves as a controlled spillway contributing to the tributary to Negro Creek. With a maximum storage capacity of 48.8 acre-feet and a normal storage of 23.5 acre-feet, this dam plays a significant role in managing water resources in the area.
Measuring 27.5 feet in height and 520 feet in length, Nolan Pool Pond No. 1 has a surface area of 4.33 acres and can handle a maximum discharge of 9.1 cubic feet per second. Despite its low hazard potential, the dam is classified as having a very high risk due to its importance in managing water flow in the region. Although the condition assessment is not rated, the pond is inspected every 5 years to ensure its safety and functionality.
As a critical water infrastructure, Nolan Pool Pond No. 1 stands as a testament to the importance of proper management and regulation of water resources. With its controlled spillway and significant storage capacity, this dam plays a crucial role in mitigating flood risks and ensuring a stable water supply for the surrounding area.

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.
