Summary
This earth dam stands at a height of 33 feet and stretches 350 feet in length, with a storage capacity of 43 acre-feet. Situated on TR- Lake Creek, the dam is regulated by the Iowa DNR and is subject to state permitting, inspection, and enforcement.
With a low hazard potential and a moderate risk assessment rating, Corey Family Farms Dam plays a crucial role in water resource management in Calhoun County. The dam's location in a rural area ensures that it primarily benefits private owners and local agricultural operations. Despite not being rated for its condition, the dam remains a key infrastructure for ensuring water availability and fire protection in the region.
Water resource and climate enthusiasts will appreciate Corey Family Farms Dam as a vital component of the local ecosystem, providing essential water storage for agricultural and fire protection purposes. The dam's earth structure and uncontrolled spillway reflect a balance between functionality and natural water flow. As a privately owned and state-regulated facility, the dam showcases the collaborative efforts needed to manage water resources effectively while mitigating potential risks and ensuring compliance with regulatory standards.

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.
