Fleming Ii Dam dam
Fleming Ii Dam
Fleming II Dam, located in Vinton, Iowa, is a privately owned structure designed by Andrew Zelinskas for the primary purpose of flood risk reduction. Completed in 2021, this earth dam stands at a height of 28 feet with a length of 400 feet, providing a storage capacity of 25 acre-feet. The dam is situated on an unnamed ephemeral stream and is regulated by the state with permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a low hazard potential and a moderate risk assessment rating, Fleming II Dam is an essential infrastructure for managing flood risks in the Tama County area. Although the dam is not equipped with outlet gates or a controlled spillway, it serves its purpose effectively in reducing the potential impact of flooding events. Despite being ungraded for its condition assessment, the dam's design and construction meet regulatory standards, providing a reliable barrier against excess water flow during periods of high precipitation.
For water resource and climate enthusiasts, Fleming II Dam represents a vital piece of infrastructure in the region's flood risk management strategy. As a privately owned structure supported by state regulatory agencies, the dam plays a crucial role in protecting the surrounding community from potential water-related hazards. With its completion in 2021 and a low hazard potential, this earth dam stands as a testament to effective engineering and design in mitigating the impact of natural disasters on the local environment.

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 Fleming Ii Dam
Where does the data for Fleming Ii 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.
