Summary
Built in 1971, this earth dam has a height of 47 feet and a length of 550 feet, serving primarily for fire protection, stock, or as a small fish pond. The dam has a normal storage capacity of 43 acre-feet and a maximum storage capacity of 102 acre-feet, with a surface area of 7.2 acres and a drainage area of 0.55 square miles.
Situated on TR-Davis Creek and under the jurisdiction of the Iowa Department of Natural Resources, Iowa Noname57 is classified as having a low hazard potential and is currently rated as not assessed for condition. Despite its moderate risk assessment level, the dam does not have an emergency action plan in place nor does it meet EAP guidelines. With no associated locks, spillway width, or maximum discharge recorded, the dam presents an opportunity for further evaluation and potential risk management measures to ensure its safety and functionality for the surrounding community and water resources.
For water resource and climate enthusiasts, Iowa Noname57 represents a unique piece of infrastructure that plays a vital role in fire protection, stock maintenance, and small fish pond operations in the area. With its location in a picturesque setting in Washington County and the potential for increased risk management measures, this dam serves as a focal point for understanding the importance of maintaining and improving water infrastructure to safeguard against potential hazards and ensure sustainable water resource management in the region.

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.
