Summary
Built in 1966 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 53 feet and a length of 830 feet, Iowa Noname33 has a storage capacity of 347 acre-feet and covers a surface area of 14.2 acres, with a drainage area of 1.46 square miles.
Managed by the Iowa Department of Natural Resources, Iowa Noname33 is regulated, permitted, inspected, and enforced by state authorities. The dam has a low hazard potential and a moderate risk assessment rating. Despite its age, the condition assessment of Iowa Noname33 is currently listed as "Not Rated," and emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps are not documented. The dam is situated on the TR-Soldier River and falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers.
Water resource and climate enthusiasts interested in Iowa Noname33 can explore its historical significance, design features, and regulatory framework. As a vital infrastructure for fire protection and water storage, this dam plays a crucial role in maintaining the ecological balance and water security in the region. With its unique location and purpose, Iowa Noname33 offers a fascinating case study for understanding the intersection of water management, environmental conservation, and community resilience in Iowa's landscape.

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.
