Summary

Constructed in 1960, this earth dam stands at a height of 23 feet and has a length of 775 feet. The primary purpose of Oknoname 087010 is classified as 'Other', with a storage capacity of 278 acre-feet and a normal storage level of 80 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last inspection conducted in July 2005.

The dam sits on the TR-North Fork Walnut Creek and is part of the Tulsa District under the jurisdiction of the US Army Corps of Engineers (USACE). Despite its low hazard potential, Oknoname 087010 is categorized as having a very high risk level, with a risk assessment rating of 1. The spillway type is controlled with a width of 1 foot, and the outlet gates consist of a single valve. Although the condition of the dam has not been rated, it meets state regulatory standards and has remained unchanged since its last inspection in 2005.

Overall, Oknoname 087010 represents a crucial water resource infrastructure in Oklahoma, serving various purposes and providing essential water storage capacity. With its strategic location in Cole and proximity to the North Fork Walnut Creek, this dam plays a significant role in managing water resources and mitigating potential risks associated with flooding. As a privately owned structure, Oknoname 087010 contributes to the overall water management efforts in the region and underscores the importance of maintaining and monitoring dams for the safety and well-being of surrounding communities.

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.
