Summary
The dam, owned privately, stands at a height of 28 feet with a length of 450 feet, holding a maximum storage capacity of 62 acre-feet. The primary purpose of the dam is to provide essential water resources for the community while also serving as a recreational area for small-scale activities.
Managed by the Iowa Department of Natural Resources, Noelck Dam is regulated, inspected, and permitted by state agencies to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, the dam poses minimal risk to surrounding areas. The risk management measures are in place to mitigate any potential issues and to ensure the dam's continued operation for the community's benefit.
Situated on TR- Drainage Ditch #6, Noelck Dam is a crucial water resource for the residents of Franklin County, Iowa. Despite being a private structure, the dam plays a vital role in water management and conservation efforts in the region. With its strategic location and well-maintained infrastructure, Noelck Dam stands as a testament to effective water resource management and climate adaptation strategies in the area.

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.
