Summary

Standing at a height of 18 feet and stretching 450 feet in length, this earth-filled dam holds a storage capacity of 55 acre-feet, with a normal storage level of 26 acre-feet. The dam, situated on the TR-North Canadian River, is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes state permitting, inspection, and enforcement processes.

Despite being rated as having a low hazard potential, Oknoname 125019 is considered to have a very high risk level, with a risk assessment score of 1. The dam features a controlled spillway and a single valve outlet gate. While the structure has not been rated for its condition, it is subject to inspections every 5 years, with the last inspection conducted in May 2011. The dam is not owned or funded by any federal agency, and its construction, design, and regulatory oversight are solely managed by the state of Oklahoma.

Water resource and climate enthusiasts intrigued by the characteristics and risk profile of dams will find Oknoname 125019 a fascinating subject of study. With its unique features, state-regulated status, and high-risk assessment, this dam serves as a compelling example of the complex interplay between infrastructure, water management, and environmental risk mitigation in the region. As a privately owned entity situated within the Tulsa District of the US Army Corps of Engineers, Oknoname 125019 offers valuable insights into the challenges and responsibilities associated with maintaining critical water infrastructure in Oklahoma.

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.
