Weimann Dam dam
Weimann Dam
Weimann Dam, located in Audubon, Iowa, is a privately owned structure with a primary purpose of fire protection and serving as a stock or small fish pond. Built in 1980 by the Soil Conservation Service (SCS), this earthen dam stands at a height of 31 feet and stretches 475 feet in length, with a storage capacity of 77 acre-feet. The dam is situated on the TR- EAST NISHNABOTNA RIVER, under the jurisdiction of the Iowa Department of Natural Resources (DNR) and is regulated, permitted, inspected, and enforced by state authorities.
The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the risk assessment for the dam is moderate, management measures have not been specified. The surrounding area has a drainage area of 0.2 square miles and a surface area of 4 acres. With its uncontrolled spillway type and no outlet gates, the dam poses minimal risk to downstream communities. Despite its condition assessment status, the dam has not been reviewed for its emergency action plan or inundation maps, indicating a need for further assessment and preparedness in case of emergencies.
Water resource and climate enthusiasts will find Weimann Dam to be an interesting case study in private dam ownership and management. With its unique purpose, location, and design characteristics, the dam serves as a reminder of the importance of regular inspection, maintenance, and emergency preparedness for ensuring the safety and sustainability of water infrastructure in the face of 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 Weimann Dam
Where does the data for Weimann 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.
