Summary
Constructed in 1966 by the USDA NRCS, this earth dam stands at a height of 29 feet and spans a length of 495 feet, with a storage capacity of 65 acre-feet. The dam is regulated by the Iowa DNR and undergoes regular inspections, ensuring its structural integrity and safety.
Despite its low hazard potential, Lynn Dam is considered to have a moderate risk level, indicating the need for proactive risk management measures. The dam's proximity to TR-Fisher Creek and its drainage area of 0.2 square miles highlight its importance in managing water resources and mitigating potential flooding risks. With a surface area of 6 acres and a normal storage capacity of 52 acre-feet, Lynn Dam plays a significant role in maintaining water quality and supporting the local ecosystem.
As water resource and climate enthusiasts, understanding the significance of Lynn Dam in the context of sustainable water management and environmental conservation is essential. With its primary purpose of fire protection and stock pond, this earth dam stands as a testament to the importance of responsible water infrastructure development. By acknowledging its role in the local ecosystem and implementing effective risk management strategies, Lynn Dam continues to be a vital asset for the community and a key player in ensuring water security for future generations.

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.
