Summary

Completed in 1960, this Earth-type dam stands at 41 feet high with a hydraulic height of 37 feet, offering a storage capacity of 450 acre-feet and a maximum discharge of 4975 cubic feet per second. The dam, situated on TR-Turkey Creek, is owned by the state and is subject to regular inspections and enforcement by the Oklahoma Water Resources Board.

With a hazard potential rated as high and a risk assessment indicating a very high risk level, SCS-Turkey Creek Site-12 poses a significant challenge in terms of risk management and emergency preparedness. Despite its fair condition assessment, the dam's emergency action plan and inundation maps are currently not up to date, raising concerns about the effectiveness of response measures in case of a breach or failure. The presence of a controlled spillway and a single valve outlet gate underscores the importance of maintaining the structural integrity of this crucial flood control infrastructure in Parkersburg.

As water resource and climate enthusiasts, the data for SCS-Turkey Creek Site-12 serves as a reminder of the complex interplay between infrastructure, regulation, and natural forces in shaping the resilience of communities to water-related hazards. The dam's association with the Tulsa District of the US Army Corps of Engineers highlights the collaborative efforts needed to address the evolving risks posed by aging infrastructure and changing environmental conditions. Moving forward, a comprehensive risk management strategy and regular maintenance of SCS-Turkey Creek Site-12 will be essential to safeguarding lives and property 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.
