Big Flat Lake Dam dam
Big Flat Lake Dam
Big Flat Lake Dam in Baxter, Arkansas, is a privately owned earth dam completed in 1966 for recreational purposes along Roasting Ear Creek. With a hydraulic height of 30 feet and a structural height of 30 feet, this low-hazard dam has a storage capacity of 50 acre-feet and a normal storage level of 30 acre-feet. The dam is situated in a picturesque location in Allison, offering a serene environment for water resource and climate enthusiasts to enjoy.
Even though Big Flat Lake Dam is not regulated by the state and has not been rated for its condition, it provides a safe recreational area for visitors to engage in various water activities. The dam's design and construction are not associated with any federal agencies, and it does not have any outlet gates or locks. Despite its simple structure, the dam continues to serve its primary purpose of providing a recreational oasis for locals and tourists to appreciate the beauty of nature.
The dam's location in the Little Rock District and its affiliation with the USACE further highlight its significance in the region. While Big Flat Lake Dam may not have a high-risk potential, its contribution to the community as a recreational resource underscores its importance in fostering a deeper connection with the environment and promoting sustainable water usage practices.

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 Big Flat Lake Dam
Where does the data for Big Flat 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.
