Summary
With a height of 25 feet and a length of 344 feet, the dam has a storage capacity of 82 acre-feet and covers a surface area of 3.3 acres. It is designed as an earth dam with a soil foundation, and is regulated by the Iowa Department of Natural Resources.
Despite being rated as having a low hazard potential and not yet assessed for its condition, Kimberly Dam is considered to have a moderate risk level. It features an uncontrolled spillway and does not have outlet gates. The dam is privately owned and falls under the jurisdiction of the state of Iowa. The surrounding area, including the TR-Silver Creek, benefits from the water storage and recreational opportunities provided by the dam.
Water resource and climate enthusiasts will appreciate the role Kimberly Dam plays in maintaining water levels, supporting wildlife, and enhancing fire protection measures in the region. Its construction by the USDA NRCS reflects a commitment to sustainable water management practices. With its strategic location and multiple benefits, Kimberly Dam represents a valuable asset in the local water infrastructure.

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.
