Summary
Constructed in 1972 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, and recreation. With a dam height of 35 feet and a storage capacity of 120 acre-feet, the structure covers a surface area of 6.8 acres and has a drainage area of 0.31 square miles.
Managed by the Iowa Department of Natural Resources, Iowa Noname51 is regulated, permitted, inspected, and enforced by state authorities. The dam's hazard potential is rated as low, with a moderate risk assessment score of 3. While its condition assessment is not rated, the dam meets state guidelines and has not been modified in recent years. Despite lacking emergency action plans and inundation maps, the structure is deemed to have effective risk management measures in place.
Located along the TR-WEST BRANCH 102 RIVER, Iowa Noname51 is under the jurisdiction of the Kansas City District of the US Army Corps of Engineers. With a spillway type of uncontrolled, the dam does not have outlet gates or locks. Overall, Iowa Noname51 is a vital infrastructure for water resource management in the region, ensuring water availability for various uses while maintaining low-risk levels for surrounding communities.

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.
