Summary
The dam serves multiple purposes, including fire protection and providing a small fish pond for local residents. With a height of 21 feet and a length of 370 feet, Mohr Dam has a storage capacity of 68 acre-feet and covers a surface area of 4 acres.
Managed by the Iowa Department of Natural Resources, Mohr Dam is regulated, inspected, and enforced to ensure its safety and functionality. Despite its low hazard potential, the dam is considered to have a moderate risk level, emphasizing the importance of regular maintenance and risk management measures. While the dam does not have an Emergency Action Plan in place, it meets state permitting and inspection requirements, making it a vital structure for water resource management in the area.
Situated on Miller Creek, Mohr Dam plays a crucial role in water conservation and management in the region. With its primary purpose being fire protection and stock enhancement, the dam provides essential services to the community of Vail. As a key component of the local water infrastructure, Mohr Dam exemplifies the intersection of water resource management and climate resilience in Iowa.

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.
