Upper Tri-County Wid Site 15 dam
Upper Tri-County Wid Site 15
Upper Tri-County Wid Site 15 is a flood risk reduction structure located in Lawrence County, Arkansas, along Piney Creek. Built in 1985 by the USDA NRCS, this earth dam stands at 29.5 feet high and spans 1085 feet in length. With a storage capacity of 653 acre-feet and a drainage area of 1.5 square miles, this dam plays a crucial role in mitigating flood risks in the region.
Managed by the local government and regulated by the Arkansas Natural Resources Commission, Upper Tri-County Wid Site 15 is inspected regularly to ensure its structural integrity and functionality. Despite its low hazard potential, the dam is considered to have a moderate risk level (3) according to the data provided. While the condition assessment is currently not rated, the dam has not required any emergency action plans or inundation maps to be prepared.
With its primary purpose being flood risk reduction, Upper Tri-County Wid Site 15 serves as a vital infrastructure for the community, protecting the surrounding areas from potential flooding events. As water resource and climate enthusiasts, understanding the design and functionality of such structures is essential in safeguarding our environment and communities from the impacts of extreme weather events.
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 Upper Tri-County Wid Site 15
Where does the data for Upper Tri-County Wid Site 15 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.
