About this dam

Scs-Little Wewoka Creek Site-15

SCS-Little Wewoka Creek Site-15, located in Hughes County, Oklahoma, is a state-owned earth dam designed by the USDA NRCS for flood risk reduction on Ranch Creek. Completed in 1958, this dam stands at a height of 27 feet and stretches 1200 feet in length, providing a maximum storage capacity of 1860 acre-feet. With a controlled spillway and one outlet valve, this dam plays a crucial role in managing floodwaters and protecting the surrounding area from potential damage.

Despite its age, SCS-Little Wewoka Creek Site-15 has a low hazard potential and has not been rated for its condition as of yet. The dam's last inspection was conducted in 1980, with a scheduled inspection frequency of 5 years. While the risk assessment for this site indicates a very high risk level, measures for risk management and emergency preparedness, such as an Emergency Action Plan (EAP), have not been reported. However, with its solid stone core and soil foundation, this dam continues to serve its primary purpose effectively while being regulated by the Oklahoma Water Resources Board.

As water resource and climate enthusiasts, the SCS-Little Wewoka Creek Site-15 presents an intriguing case study of a historic earth dam still in operation today. Its location in a state-regulated jurisdiction and the involvement of the USDA NRCS in its design highlight the collaborative efforts needed to address flood risk and water management challenges in the region. Further monitoring and assessment of this dam's condition and risk management practices could provide valuable insights for similar infrastructure projects in the future.

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-Little Wewoka Creek Site-15

Where does the data for Scs-Little Wewoka Creek Site-15 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.
