Bentley Dam dam
Bentley Dam
Bentley Dam, located in Benton, Iowa, is a private dam designed by the USDA NRCS with a primary purpose of grade stabilization. Completed in 2013, this earth dam stands at 26 feet high and spans 766 feet in length, providing a storage capacity of 35 acre-feet. The dam serves multiple purposes including grade stabilization, recreation, and water supply, making it a vital infrastructure for the local community.
Situated on a tributary to Wolf Creek, Bentley Dam plays a crucial role in managing water resources in the region, with a maximum discharge capacity of 138 cubic feet per second. Despite its low hazard potential, the dam's condition is currently not rated, highlighting the need for regular inspections and maintenance to ensure its structural integrity and safety. With a surface area of 5 acres and a drainage area of 0.05 square miles, Bentley Dam contributes to the overall water management and conservation efforts in Ringgold County, Iowa.
As a key feature of the local landscape, Bentley Dam offers opportunities for recreational activities and water supply while also serving as a vital asset for grade stabilization. While its risk assessment and emergency preparedness measures are currently unspecified, the dam's presence underscores the importance of sustainable water resource management and climate resilience in the face of increasing environmental challenges. Bentley Dam stands as a testament to the collaborative efforts between private owners and government agencies in safeguarding water resources and enhancing community well-being in the region.

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 Bentley Dam
Where does the data for Bentley 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.
