Iowa Noname81 dam
Iowa Noname81
Iowa Noname81 is a privately owned dam located in Warren, Iowa, along the DES MOINES RIVER. Built in 1974 by USDA NRCS, this earth dam stands 29 feet tall and spans 345 feet in length, with a storage capacity of 49 acre-feet. It serves multiple purposes including fire protection, stock or small fish pond, and recreation, making it a vital resource for the local community.
Managed by the Iowa Department of Natural Resources, Iowa Noname81 is state-regulated and undergoes regular inspections and enforcement to ensure its safety. Despite being classified as having a low hazard potential, it has a moderate risk assessment due to its location along the TR-BUTCHER CREEK and a drainage area of 0.17 square miles. While its condition is currently not rated, the dam continues to play a crucial role in water resource management and recreation in the area.
With a surface area of 4.2 acres and a normal storage capacity of 17 acre-feet, Iowa Noname81 offers a peaceful retreat for outdoor enthusiasts and serves as a key component in the local ecosystem. As climate change continues to impact water resources, the maintenance and regulation of dams like Iowa Noname81 are essential in ensuring the safety and sustainability of our water supply for future generations.

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 Iowa Noname81
Where does the data for Iowa Noname81 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.
