Summary
This earth dam stands at a height of 36 feet and stretches 352 feet in length, offering a storage capacity of 36 acre-feet. Situated along TR- Rocky Run, the dam serves the purpose of providing water for agricultural and recreational needs in the area. Despite its low hazard potential and moderate risk assessment, the dam is regulated, permitted, inspected, and enforced by the Iowa Department of Natural Resources to ensure its safety and functionality.
Owned by a private entity, Seven Cedars Farms Dam is located in Crawford County, Iowa, and falls under the jurisdiction of the Iowa DNR. With a surface area of 2.5 acres and a drainage area of 0.14 square miles, the dam serves as a vital water resource for the surrounding community. Although the dam's condition assessment is currently not rated, its risk management measures are in place to address any potential issues that may arise in the future. With its strategic location and purposeful design, Seven Cedars Farms Dam stands as a testament to sustainable water resource management in the region, catering to the needs of both humans and wildlife alike.

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.
