Maertens Lake Dam dam
Maertens Lake Dam
Maertens Lake Dam, located in Benton, Arkansas, was completed in 1948 by the USDA NRCS and serves as a recreational water resource on Dry Creek Tributary. With a height of 33 feet and a length of 450 feet, this earth dam provides a maximum storage capacity of 132 acre-feet and a normal storage of 89 acre-feet. Despite being classified as a low hazard potential structure, it is subject to state regulation, inspection, and enforcement by the Arkansas Natural Resources Commission.
The dam's spillway type is uncontrolled, with a maximum discharge capacity of 3451 cubic feet per second. The surrounding surface area covers 5.9 acres, with a drainage area of 0.05 square miles. While the condition assessment is currently not rated, the risk assessment indicates a moderate level of risk (3) associated with the structure. Maertens Lake Dam does not have an Emergency Action Plan prepared, and there is no updated information on emergency contacts or inundation maps.
For water resource and climate enthusiasts, Maertens Lake Dam presents an interesting case study in dam management and risk assessment. Its history, design features, and ongoing regulatory oversight provide valuable insights into the intersection of water infrastructure, environmental conservation, and public safety. As the dam continues to serve its primary purpose for recreation, monitoring its condition and implementing risk management measures will be crucial in ensuring its long-term sustainability and resilience to changing climate conditions.

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 Maertens Lake Dam
Where does the data for Maertens 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.
