Summary
The dam, built in 2004 by the NRCS, is an earth dam with a height of 25 feet and a length of 592 feet. It holds a storage capacity of 174 acre-feet with a normal storage level of 69 acre-feet, covering a surface area of 11.6 acres and draining a 0.83 square mile watershed.
The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating of 3. Chizek Dam features an uncontrolled spillway with a width of 3 feet and does not have any associated locks or outlet gates. Despite its relatively low hazard potential, the dam's condition assessment is currently labeled as "Not Rated," indicating the need for further evaluation and potential maintenance to ensure its continued safety and functionality for the surrounding community and wildlife.
Water resource and climate enthusiasts will appreciate Chizek Dam as a vital infrastructure piece in managing water resources for fire protection, livestock, and fishpond purposes. Its design and construction by the NRCS demonstrate a commitment to sustainable water management practices, while its regulation by the Iowa DNR ensures compliance with state standards for dam safety. As climate change continues to impact water resources and infrastructure, Chizek Dam serves as a critical component in mitigating risks and protecting the surrounding environment and community from potential hazards.

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.
