Dequeen Dam - Saddle Dike C dam
Dequeen Dam - Saddle Dike C
Dequeen Dam - Saddle Dike C, also known as Dequeen Lake, is a federal-owned Earth dam located on Rolling Fork in Sevier County, Arkansas. Completed in 1977 by the US Army Corps of Engineers, the dam stands at a height of 160 feet and has a hydraulic height of 145 feet. Its primary purpose is flood risk reduction, but it also serves for recreation and water supply. The dam has a high hazard potential and a reservoir storage capacity of 370,600 acre-feet.
The US Army Corps of Engineers actively manages the flood risks associated with Dequeen Dam by continuously monitoring its condition and engaging with local emergency managers and the public to raise awareness and preparedness. Regular maintenance and repairs are conducted to ensure the dam's structural integrity and functionality. Despite the risk management measures in place, severe weather events that bring large amounts of water into the system can potentially overwhelm the dam, leading to issues.
Dequeen Dam is an essential structure for flood risk reduction in the area, with measures in place to address potential emergencies. The Corps works collaboratively with local stakeholders to ensure the dam's safety and functionality, while striving to enhance public awareness and emergency preparedness. More detailed information about the dam's risk management and operations will be added in the future.

About Dequeen Dam - Saddle Dike C
Where does the data for Dequeen Dam - Saddle Dike C 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 below 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.

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.
