Area 7 Section 4 dam
Area 7 Section 4
Area 7 Section 4, located in Jefferson County, Arkansas, is a Federal-owned earth dam designed by the US Army Corps of Engineers with a primary purpose of flood risk reduction along the tributary of the Arkansas River. Completed in 1988, this dam stands at a height of 27 feet and has a hydraulic height of 20 feet, providing a maximum storage capacity of 144 acre-feet and a normal storage of 72 acre-feet. With a controlled spillway width of 30 feet, the dam has a low hazard potential and a very high risk assessment rating.
Despite its age, the condition assessment of Area 7 Section 4 is currently listed as "Not Available", and the last inspection date was in July 2019. The dam is equipped with slide gates for outlet control and has an inspection frequency of 4 years. While an Emergency Action Plan (EAP) was prepared in the past, its last revision date was in 2007. Although the risk assessment indicates a very high risk level, specific risk management measures and a detailed risk characterization summary are not available at this time. Overall, Area 7 Section 4 serves as a crucial infrastructure for flood risk mitigation in the region, highlighting the importance of regular maintenance and monitoring to ensure its effectiveness and safety.
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.
Plan around the weather

About Area 7 Section 4
Where does the data for Area 7 Section 4 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.
