Powell Reservoir dam
Powell Reservoir
Powell Reservoir, located in St. Francis County, Arkansas, is a private irrigation reservoir managed by the USDA NRCS for the purpose of providing water for agricultural use. Completed in 1983, this earth dam structure stands at a height of 7 feet and has a storage capacity of 650 acre-feet. The reservoir is situated along Second Creek and covers a surface area of 0 acres.
Although the dam is primarily used for irrigation, it also serves as a fish and wildlife pond. The reservoir has a high hazard potential and its condition assessment is currently marked as 'Not Available'. With a maximum storage capacity of 650 acre-feet and normal storage of 500 acre-feet, Powell Reservoir plays a crucial role in managing water resources in the region. Despite the lack of certain data points, the reservoir remains an essential asset for water supply and agriculture in the area.
As a key feature in the water infrastructure of Palestine, Arkansas, Powell Reservoir contributes to the overall water management strategy in the region. While there are no specific details on inspections or emergency preparedness, the reservoir's importance in irrigation and its high hazard potential underscore the need for ongoing monitoring and maintenance to ensure water resource sustainability and safety for the community.

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 Powell Reservoir
Where does the data for Powell Reservoir 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.
