Iowa Noname11 dam
Iowa Noname11
Iowa Noname11 is a state-regulated earth dam located in Decatur County, Iowa, serving multiple purposes including fire protection, stock, small fish pond, and recreation. Built in 1969, the dam stands at a height of 44 feet and has a length of 840 feet, with a storage capacity of 276 acre-feet. Situated on the TR-Dickerson Branch river, the dam's hazard potential is rated as low, with a moderate risk assessment score of 3.
Owned and regulated by the Iowa Department of Natural Resources, Iowa Noname11 is inspected, permitted, and enforced by state agencies, ensuring safety and compliance with regulations. Although the dam's condition assessment is not rated, its risk management measures are currently unspecified. The dam's location in Cainsville, MO, and its proximity to Rock Island District adds to its significance and interest for water resource and climate enthusiasts in the region.
Overall, Iowa Noname11 presents an intriguing case study for water resource and climate enthusiasts, showcasing the intersection of dam infrastructure, environmental management, and regulatory oversight. With its diverse purposes, low hazard potential, and moderate risk assessment, this earth dam in Decatur County, Iowa, offers a glimpse into the complexities of managing water resources for various needs while ensuring safety and compliance with state regulations.

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 Noname11
Where does the data for Iowa Noname11 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.
