Summary
Built in 1963 by the USDA NRCS, this earth dam stands at a height of 40 feet and has a length of 421 feet. The primary purposes of the dam include fire protection, stock, small fish pond, and recreation. With a storage capacity of 143 acre-feet, the dam covers a surface area of 4 acres and drains a 0.31 square mile watershed.
Managed by the Iowa Department of Natural Resources, Iowa Noname6 is regulated, permitted, inspected, and enforced by state agencies. Despite being classified as a low hazard potential structure, the dam is considered to have a moderate risk level. However, its condition assessment is currently not rated, and no emergency action plan (EAP) has been prepared. With its location in the Rock Island District and oversight by the Natural Resources Conservation Service, Iowa Noname6 serves as a crucial structure for water resource management in the region.
For water resource and climate enthusiasts, Iowa Noname6 presents an interesting case study in dam infrastructure. Its design and construction by USDA NRCS, private ownership, and multi-purpose usage highlight the complex interplay between human development and natural ecosystems. With ongoing regulatory oversight and risk management efforts, this dam underscores the importance of maintaining and monitoring critical water infrastructure to ensure public safety and environmental sustainability in the face of changing climate conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
