Sardis Dam dam
Sardis Dam
Sardis Dam, also known as Sardis Lake, is a significant federal structure located in Pushmataha County, Oklahoma. Completed in 1982 by the US Army Corps of Engineers, the dam stands at 83 feet in height and serves the primary purpose of flood risk reduction. With a storage capacity of 735,830 acre-feet and a surface area of 13,610 acres, Sardis Dam plays a crucial role in mitigating potential flooding events in the region.
However, a risk assessment conducted by the USACE in December 2015 classified Sardis Dam's risk level as moderate, primarily due to the potential for water seepage through the embankment and the remote possibility of embankment erosion and breach. To manage and reduce this risk, the USACE has implemented an interim risk reduction plan, which includes repairs to the dam, enhanced monitoring systems, and regular emergency exercises with local and state responders. These proactive measures aim to ensure the structural integrity of the dam and minimize the potential impacts of a dam failure on downstream communities like Clayton and Antlers.
In addition, the USACE conducts routine inspections, maintenance activities, and detailed monitoring of Sardis Dam to promptly address any changes in conditions and ensure the safety of the surrounding area. With a comprehensive risk management strategy in place, Sardis Dam continues to play a vital role in safeguarding the region against flooding events while prioritizing public safety and infrastructure integrity.

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 Sardis Dam
Where does the data for Sardis Dam 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.
