Poinsett Wid Site 118 dam
Poinsett Wid Site 118
Poinsett Wid Site 118 is a vital earth dam located in Greenfield, Arkansas, designed by the USDA NRCS to primarily reduce flood risk in the area. Completed in 1985, this dam stands at 19 feet in height and spans 1200 feet in length, with a storage capacity of 59 acre-feet. With a high hazard potential and moderate risk assessment rating, the dam is crucial for protecting the local community from potential flooding events.
Managed by the local government and regulated by the state of Arkansas, Poinsett Wid Site 118 plays a key role in flood risk reduction for the surrounding area, including the Ditch No. 1 - TR waterway. Despite being uncontrolled, the spillway and outlet gates help manage water discharge, with a maximum capacity of 774 cubic feet per second. Although the dam's condition is currently not rated and the last inspection was in 2014, its strategic location and design ensure it continues to serve its purpose effectively.
Water resource and climate enthusiasts will appreciate the engineering behind Poinsett Wid Site 118, as it showcases the importance of proper flood risk management in vulnerable areas. With a focus on protecting the community and surrounding environment, this earth dam stands as a testament to the collaborative efforts of the USDA NRCS, local government, and state regulatory agencies in safeguarding water resources and mitigating the impacts of extreme weather events in Poinsett County, Arkansas.

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 Poinsett Wid Site 118
Where does the data for Poinsett Wid Site 118 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.
