Summary
Built in 1965, this earth dam stands at a height of 45 feet and spans 400 feet in length, with a storage capacity of 106 acre-feet. The dam serves as a recreational spot and provides essential water resources for the surrounding area.
Managed by the Iowa Department of Natural Resources, Meyer Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. With a hazard potential classified as high and a condition assessment rated as fair, the dam poses moderate risks and is subject to regular inspections to mitigate any potential dangers. Despite its moderate risk level, the dam continues to meet guidelines and provide valuable water resources for the community.
In case of emergencies, the dam's emergency action plan remains up to date, and risk management measures are in place to address any potential threats. With its strategic location on the TR-East Boyer River, Meyer Dam plays a crucial role in water management and conservation efforts in Crawford County, Iowa, serving as a vital resource for both humans and wildlife 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.
