Summary
Built in 1981 by the USDA NRCS, the dam serves multiple purposes including fire protection and creating a small fish pond. With a height of 29 feet and a length of 211 feet, it provides storage for up to 20 acre-feet of water and covers a surface area of 1.3 acres. Despite its low hazard potential, the dam is regulated by the Iowa Department of Natural Resources and is subject to regular inspections and enforcement measures.
The dam's design features an earth structure with a soil foundation, making it essential for water resource management in the area. While the spillway is uncontrolled, the dam has not experienced any modifications since its completion. Though it is not rated for condition assessment, the risk assessment is moderate with a score of 3, signaling the importance of ongoing monitoring and maintenance. With its strategic location and contribution to local water management efforts, Fogelman Dam plays a crucial role in sustaining the surrounding ecosystem and supporting agricultural activities.
Overall, Fogelman Dam stands as a testament to effective collaboration between private owners and state agencies in ensuring water resource sustainability. Its presence not only provides essential services for fire protection and stock pond maintenance but also underscores the importance of proactive risk management in the face of climate challenges. As an integral part of the local landscape, the dam serves as a reminder of the intricate balance between human intervention and natural processes in maintaining a resilient water infrastructure 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.
