Scs-Chigley Sandy Creek Site-11 dam
Scs-Chigley Sandy Creek Site-11
SCS-Chigley Sandy Creek Site-11, located in Davis, Oklahoma, is a state-regulated earth dam constructed in 1955 by USDA NRCS with a primary purpose of flood risk reduction along the TR-Chigley Sandy Creek. The dam stands at a height of 26 feet with a hydraulic height of 20 feet and a length of 1560 feet, providing a storage capacity of 117 acre-feet. Despite being categorized as low hazard potential, the risk assessment indicates a very high risk level, emphasizing the importance of regular inspections and maintenance to ensure public safety.
Managed by the Oklahoma Water Resources Board (OWRB), this dam features a controlled spillway and a single valve outlet gate. While the condition assessment currently remains unrated, the dam has not undergone any modifications since its construction. The site falls under the jurisdiction of the state regulatory agency and undergoes regular inspections, enforcement, and permitting to ensure compliance with safety standards. With a congressman representative of Tom Cole (R), the dam serves as a crucial infrastructure for flood control in Murray County, Oklahoma, highlighting the collaboration between state and federal agencies in managing water resources in the region.
In the realm of water resource and climate management, SCS-Chigley Sandy Creek Site-11 presents an intriguing case study of a state-maintained earth dam designed for flood risk reduction. The site's historical significance dates back to 1955, showcasing early efforts in water infrastructure development to mitigate the impacts of natural disasters in the region. With a focus on safety and risk management, this dam serves as a vital component of the local watershed, requiring ongoing monitoring and assessment to address potential hazards and ensure the resilience of the surrounding communities.

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-Chigley Sandy Creek Site-11
Where does the data for Scs-Chigley Sandy 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.
