Summary
Built in 1960, this earthen dam stands at 35 feet high and stretches 387 feet in length, with a storage capacity of 170 acre-feet. It serves as a vital structure for managing water resources along the TR-Gaddis Creek, a tributary of the Canadian River, in the Tulsa District.
Despite its low hazard potential, Oknoname 087044 is deemed to have a very high risk level, indicating the importance of proper risk management measures. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in July 2005. With a controlled spillway and a single valve outlet gate, the dam plays a crucial role in flood control and water storage in the region.
Water resource and climate enthusiasts would find Oknoname 087044 to be an intriguing structure, given its significance in managing water flow and storage in the area. Its location and design details provide valuable insights into the intersection of infrastructure, environmental management, and public safety. As a key component of the local water management system, this dam underscores the importance of maintaining and monitoring critical infrastructure to ensure the resilience of water resources in the face of climate challenges.

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.
