Iowa Noname3 dam
Iowa Noname3
Iowa Noname3, located in Rathbun Reservoir, Appanoose County, Iowa, is a privately-owned earth dam completed in 1972 for fire protection, stock, or small fish pond purposes. Managed by the Iowa Department of Natural Resources, this dam has a height of 36 feet and a length of 352 feet, with a storage capacity of 58 acre-feet. The dam sits on the TR-Chariton River and is regulated and inspected by state authorities to ensure its safety and functionality.
Despite its low hazard potential and moderate risk assessment, Iowa Noname3 has not been rated for its condition. The dam features an uncontrolled spillway and is situated in a drainage area of 0.2 square miles. With a surface area of 3 acres and a normal storage capacity of 24 acre-feet, the dam serves as a crucial water resource in the region. Although last inspected in 1988, the dam's risk management measures and emergency action plans are yet to be fully assessed and updated.
As a key infrastructure in the Rock Island District, Iowa Noname3 plays a vital role in water resource management and climate resilience efforts in the area. With its unique design by USDA NRCS and oversight by state agencies, the dam serves as a valuable asset for local communities and wildlife. As water resource and climate enthusiasts, it is essential to monitor and support the maintenance and regulation of structures like Iowa Noname3 to ensure their long-term sustainability and effectiveness in safeguarding water resources and ecosystems.

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 Noname3
Where does the data for Iowa Noname3 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.
