Mountain Brook Dam dam
Mountain Brook Dam
Mountain Brook Dam, located in Benton, Arkansas, stands as a crucial infrastructure for flood risk reduction along the Jefferson Spring Branch. Built in 1997, this private-owned Earth dam reaches a height of 51 feet and spans 367 feet in length, with a storage capacity of 266 acre-feet. Despite a relatively low hazard potential, the dam has not been rated for its condition as of yet, indicating a need for further assessment and maintenance.
The dam also serves a secondary purpose of recreation, attracting water resource and climate enthusiasts to its serene surroundings. With a normal storage capacity of 133 acre-feet and a surface area of 9 acres, Mountain Brook Dam offers opportunities for outdoor activities and wildlife observation. While the dam has not undergone recent modifications or inspections, it remains under the regulatory oversight of the Arkansas Natural Resources Commission (ANRC) for permitting, inspection, and enforcement.
Overall, Mountain Brook Dam stands as a dual-functioning structure that not only mitigates flood risks but also provides a recreational space for the community. As climate change impacts water resources, maintaining the integrity and safety of dams like Mountain Brook becomes increasingly essential. With proper assessment, monitoring, and management, this dam can continue to fulfill its vital role while offering a haven for nature enthusiasts in the heart of 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 Mountain Brook Dam
Where does the data for Mountain Brook 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.
