Iowa Noname84 dam
Iowa Noname84
Iowa Noname84 is a dam located in Washington County, Iowa, specifically in the city of Coppock. Built in 1974 by the Washington County Engineer, this earth-type dam stands at a height of 39 feet and spans a length of 600 feet. With a primary purpose of providing fire protection and serving as a stock or small fish pond, Iowa Noname84 has a storage capacity of 88 acre-feet and covers a surface area of 5 acres.
Managed and regulated by the Iowa Department of Natural Resources, Iowa Noname84 is classified as a low hazard potential dam with a moderate risk assessment rating. While its condition assessment is currently not rated, the dam is subject to state inspection, permitting, and enforcement. Situated along the TR-Dutch Creek, this dam plays a crucial role in water resource management and protection within the region.
Enthusiasts of water resources and climate in Iowa will find Iowa Noname84 to be an intriguing infrastructure project that demonstrates the intersection of local government ownership, environmental regulation, and community safety. With its modest size and purposeful design, this dam serves as a valuable asset for fire protection and wildlife support while also highlighting the importance of responsible dam management in the face of changing climate conditions and water resource challenges.
Dam data reference
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.
Plan around the weather

About Iowa Noname84
Where does the data for Iowa Noname84 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.
