Scs-Turkey Creek Site-11 dam
Scs-Turkey Creek Site-11
SCS-Turkey Creek Site-11, located in Foss, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS with a primary purpose of flood risk reduction. Completed in 1960, this structure stands at a height of 38 feet and has a hydraulic height of 34 feet, providing a storage capacity of 362 acre-feet and a normal storage level of 130 acre-feet. The dam spans a length of 1280 feet and features a controlled spillway with a width of 1 foot.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Turkey Creek Site-11 indicates a very high risk level (1). The dam is equipped with a single valve outlet gate and has not undergone a condition assessment or emergency action plan preparation. The last inspection date recorded for this site dates back to January 1, 1980, with an inspection frequency of every 5 years.
Water resource and climate enthusiasts interested in the management and regulation of dams will find SCS-Turkey Creek Site-11 to be a notable case study due to its design by the USDA NRCS and state jurisdiction under the OWRB. The dam's location on TR-Sand Creek in Washita County, Oklahoma, offers insight into flood risk reduction strategies and highlights the importance of ongoing maintenance and risk management measures for ensuring the safety and integrity of water infrastructure 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.
- 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.

About Scs-Turkey Creek Site-11
Where does the data for Scs-Turkey Creek Site-11 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.
