Summary

Built in 1960 by GROSSMAN & KEITH ENGINEERING, this dam stands at a height of 13.2 feet and has a storage capacity of 139 acre-feet. The dam, situated on a tributary of Rock Creek, covers a surface area of 9.1 acres and has a maximum discharge capacity of 23 cubic feet per second.

Despite its low hazard potential, Oknoname 027014 is classified as having a very high risk level. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last one conducted in February 2001. While the dam is not currently rated for its condition, it has a controlled spillway and a single valve outlet gate. The surrounding area of Norman, Oklahoma, enjoys the recreational benefits of this dam, which adds to the charm of the landscape.

Water resource and climate enthusiasts would be intrigued by the technical specifications and regulatory oversight of Oknoname 027014. With its historical significance dating back to the 1960s, this dam continues to provide recreational opportunities while being closely monitored for safety and maintenance. The dam's association with the Tulsa District of the US Army Corps of Engineers adds to its significance in water resource management in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
