Dequeen Dam dam
Dequeen Dam
Dequeen Dam, also known as Dequeen Lake, is a federal-owned rockfill dam located in Sevier County, Arkansas. Completed in 1977, the dam serves multiple purposes including flood risk reduction, recreation, and water supply. Standing at a height of 160 feet with a hydraulic height of 145 feet, Dequeen Dam has a storage capacity of 370,600 acre-feet and a surface area of 1,700 acres.
Managed by the US Army Corps of Engineers, Dequeen Dam is equipped with an uncontrolled spillway and slide gates for water release. The dam poses a high hazard potential and undergoes regular inspections and emergency action plan updates to ensure public safety. USACE actively manages flood risks associated with the dam by monitoring its condition, prioritizing risk mitigation activities, and collaborating with local emergency managers to prepare for potential emergencies.
Despite the inherent risks associated with dam operations, USACE's comprehensive risk management measures aim to minimize the likelihood of dam-related emergencies and ensure the structural integrity of Dequeen Dam. By engaging with the community, implementing maintenance and repair strategies, and regularly updating emergency action plans, Dequeen Dam stands as a critical infrastructure for water resource management and climate resilience in the region.
Dam data reference
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 Dequeen Dam
Where does the data for Dequeen 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.
