Summary
Built in 1972 by the USDA NRCS, this earth dam stands at 47 feet tall and stretches 411 feet in length, with a storage capacity of 488 acre-feet. While primarily used for recreation, the dam is also regulated by the IOWA DNR and undergoes state permitting, inspection, and enforcement to ensure its safety and compliance with regulations.
Despite being classified as having a low hazard potential, the dam at Iowa Noname22 is considered to have a moderate risk level, with a rating of 3. Although the condition assessment is currently listed as "Not Rated," the dam is regularly monitored for any necessary maintenance or repairs. In the event of an emergency, the dam does not have an emergency action plan prepared, but the local government owner, Riverside, Iowa, is responsible for managing any risks and ensuring the safety of the surrounding area.
Water resource and climate enthusiasts will find Iowa Noname22 to be an intriguing site for its unique design and purpose, as well as its location within the picturesque landscape of Iowa. With its regulated status and ongoing risk assessment, this dam serves as a vital component of the local community while also highlighting the importance of maintaining infrastructure for both recreational and safety purposes in the face of changing environmental 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.
