Iowa Noname20 dam
Iowa Noname20
Iowa Noname20 is a small earth dam located in the Humboldt County of Iowa, specifically in the city of Dakota City. Completed in 1968, this dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 21 feet and a length of 360 feet, Iowa Noname20 has a storage capacity of 81 acre-feet and covers a surface area of 4.9 acres. It is regulated by the Iowa Department of Natural Resources and undergoes regular inspections and enforcement to ensure its safety and compliance.
The dam's primary purpose is to provide essential services such as fire protection and livestock watering, while also supporting recreational activities such as fishing. Despite being classified as having a low hazard potential, Iowa Noname20 is considered to have a moderate risk level, highlighting the importance of ongoing risk assessment and management measures. The dam is located on the TR-East Branch Des Moines River and falls under the jurisdiction of the St. Paul District of the US Army Corps of Engineers, ensuring proper oversight and regulation to protect the surrounding community and environment.
As a vital infrastructure for the local area, Iowa Noname20 plays a crucial role in water resource management and climate resilience efforts. With its regulated state permitting, inspection, and enforcement, the dam serves as a model for responsible dam ownership by local government agencies. Its strategic location and purposeful design make it a valuable asset for both emergency preparedness and everyday water supply needs, showcasing the importance of sustainable 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 Iowa Noname20
Where does the data for Iowa Noname20 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.
