Dierks Dam dam
Dierks Dam
Dierks Dam, also known as Dierks Lake, is a rockfill dam located in Sevier, Arkansas, with a primary purpose of flood risk reduction. Completed in 1975 by the US Army Corps of Engineers, this dam stands at a height of 153 feet and has a maximum storage capacity of 159,500 acre-feet. With a spillway width of 780 feet, the dam can release water to manage levels and relieve pressure during severe weather events.
Despite being classified as having a high hazard potential, Dierks Dam is equipped with an Emergency Action Plan (EAP) that meets guidelines and is regularly updated. The US Army Corps of Engineers actively manages flood risks associated with the dam by monitoring its condition, prioritizing maintenance activities, and engaging with emergency managers and the public to raise awareness and preparedness for potential dam-related emergencies. Regular maintenance and repairs are conducted to ensure the dam's structural integrity and functionality.
Overall, Dierks Dam serves as a critical infrastructure for flood risk reduction, recreation, and water supply in the region. The dam's management practices and risk mitigation measures by the US Army Corps of Engineers demonstrate a commitment to safeguarding the surrounding communities and environment from potential dam-related hazards.
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 Dierks Dam
Where does the data for Dierks 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.
