Summary
Built in 1976 by the USDA NRCS, this earth dam stands at 27 feet in height and spans 420 feet in length. With a primary purpose of fire protection, stock, or small fish pond, the dam has a storage capacity of 97 acre-feet and covers a surface area of 7.9 acres.
Managed by the Iowa DNR, Iowa Noname71 is regulated by the state and undergoes regular inspections, permitting, and enforcement. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level (3). While its condition is not currently rated, the dam is in operation and serves its designated purposes effectively.
Located in a rural area of Iowa, Iowa Noname71 plays a vital role in water resource management and supports local fire protection and agricultural activities. With its historical significance dating back to the 1970s, the dam continues to be a critical infrastructure in the region and is closely monitored by state regulatory agencies to ensure its safety and functionality.

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.
