About this dam

Scs-Double Creek Site-5

SCS-Double Creek Site-5, located in Ramona, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS for flood risk reduction along the Nellie Bly Creek. Completed in 1954, this dam stands at a height of 44 feet with a hydraulic height of 35 feet and a structural height of 40 feet. It has a storage capacity of 1,245 acre-feet and a normal storage of 155 acre-feet.

With a high hazard potential and fair condition assessment, SCS-Double Creek Site-5 poses a significant risk in case of a breach. The dam features a controlled spillway and a single valve outlet gate for water release. Despite its age, the dam has undergone regular inspections, with the last one conducted in November 2011. Its risk assessment is classified as very high, indicating the need for proactive risk management measures.

Given its critical role in flood risk reduction in the area, SCS-Double Creek Site-5 serves as a vital infrastructure for water resource management in Washington County, Oklahoma. Its association with the USDA NRCS underscores the commitment to sustainable water resource practices and highlights the importance of dam safety and maintenance in mitigating potential risks associated with extreme weather events 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-Double Creek Site-5

Where does the data for Scs-Double Creek Site-5 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 High 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.
