Cooper Creek Wid Site 4 dam
Cooper Creek Wid Site 4
Cooper Creek Wid Site 4 is a local government-owned earth dam in Smithville, Arkansas, designed by the USDA NRCS. The dam, completed in 1969, stands at a height of 50 feet and spans a length of 3485 feet, with a storage capacity of 2922 acre-feet and a normal storage of 91 acre-feet. It serves the primary purpose of flood risk reduction on Machine Creek, a tributary in Lawrence County, Arkansas.
With a high hazard potential and a moderate risk assessment rating, Cooper Creek Wid Site 4 is a significant infrastructure for managing flood risk in the area. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 5088 cubic feet per second. While the dam's condition assessment is currently listed as "Not Rated," it is under state regulation and inspection, ensuring its continued safety and functionality for the surrounding community.
Water resource and climate enthusiasts will appreciate the vital role that Cooper Creek Wid Site 4 plays in flood risk reduction in the region. Its strategic location and design by the USDA NRCS highlight the importance of sustainable water management practices in mitigating the impact of extreme weather events on local communities. As a key structure in the watershed, this dam serves as a crucial component of the area's resilience against flooding and underscores the need for ongoing maintenance and monitoring to ensure its long-term effectiveness in protecting the surrounding area from potential water-related hazards.

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 Cooper Creek Wid Site 4
Where does the data for Cooper Creek Wid Site 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 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.
