About this dam

Scs-Tri-County Turkey Creek Site-20

SCS-Tri-County Turkey Creek Site-20 is a state-regulated earth dam located in Duke, Oklahoma on TR-Cottonwood Creek. Built in 1967 by the USDA NRCS, this dam stands at a height of 25 feet and has a maximum storage capacity of 292 acre-feet. Designed primarily for flood risk reduction, the dam has a controlled spillway and is equipped with a single valve outlet gate.

Despite its low hazard potential, SCS-Tri-County Turkey Creek Site-20 is classified as having a very high risk due to its structural condition not being rated. The last inspection of the dam was conducted in June 1988, with an inspection frequency of every 5 years. With a risk management plan not specified, the dam's emergency action plan status and adherence to guidelines are also unknown.

Water resource and climate enthusiasts will find SCS-Tri-County Turkey Creek Site-20 an intriguing case study in dam infrastructure management. The dam's location in Harmon County, Oklahoma, its design specifications, and the potential risks associated with its condition make it a noteworthy site for further study and monitoring in the context of water resource management and climate change impacts.

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.
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.
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.

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, environmental 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.

FAQ

About Scs-Tri-County Turkey Creek Site-20

Where does the data for Scs-Tri-County Turkey Creek Site-20 come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Low hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
