Dunbar Lake Dam dam
Dunbar Lake Dam
Dunbar Lake Dam in Arkansas serves as a vital water supply resource, completed in 1964 and standing at a structural height of 12 feet with a hydraulic height of 9 feet. Located in Little River County, the dam sits on the Walnut Bayou-TR river or stream and has a maximum storage capacity of 58 acre-feet, with normal storage at 29 acre-feet. The dam is primarily used for water supply purposes and is privately owned, with no state regulation or permitting requirements.
Although the dam is classified as having a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it has not undergone recent inspections or maintenance assessments. Despite its relatively modest size and capacity, Dunbar Lake Dam plays a crucial role in providing water resources to the surrounding area. With no state jurisdiction or enforcement responsibilities, the dam's operational status and safety measures may rely heavily on the discretion of its private owners.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like Dunbar Lake Dam in sustaining local water supplies and ecosystems. Monitoring and ensuring the safety and maintenance of dams like this one is essential for safeguarding both water resources and the surrounding communities that rely on them for their daily needs.

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 Dunbar Lake Dam
Where does the data for Dunbar Lake Dam 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.
