Summary
Constructed in 1997 by the USDA NRCS, this dam serves primarily for recreation purposes with a maximum storage capacity of 195.1 acre-feet and a normal storage level of 77.8 acre-feet. The dam stands at 19.7 feet high and spans 400 feet in length, with a controlled spillway and a single valve outlet gate.
Although the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it is located in an area with very high risk, as indicated by a risk assessment score of 1. While the dam has not been modified in recent years, it is subject to regular inspections every 5 years, with the last inspection conducted in August 2011. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and meets state permitting, inspection, and enforcement requirements.
For water resource and climate enthusiasts, Okname 30144 presents an intriguing case study of a privately owned dam in Oklahoma that provides important recreational opportunities while also posing potential risks due to its location in a high-risk area. With its unique design and purpose, this dam serves as a vital water management structure along the South Canadian River, highlighting the complex interplay between water resource management, regulatory oversight, and public safety in the face of changing climate conditions.

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.
