Summary
Designed by the USDA NRCS, this earth dam stands at a height of 29 feet and spans a length of 453 feet, with a storage capacity of 38 acre-feet. The dam serves multiple purposes including fire protection and creating a small fish pond, making it a versatile resource for the local community.
With a low hazard potential and a moderate risk assessment rating, Claiser Dam plays a crucial role in water resource management and climate resilience in the region. As a state-regulated structure under the jurisdiction of the Iowa DNR, the dam undergoes regular inspections and enforcement measures to ensure its safety and functionality. Situated on TR-Three Mile Creek, the dam's location in Talmage not only provides essential water storage but also contributes to environmental conservation efforts in the area.
Despite being a private-owned facility, Claiser Dam's significance extends beyond its primary purposes, making it a valuable asset for water supply and ecosystem preservation. With its strategic design and operational efficiency, the dam stands as a testament to sustainable water management practices in Iowa, supported by the collaborative efforts of various state and federal agencies to uphold its integrity and safety for the community's benefit.

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.
