Summary
This earth dam, designed by USDA NRCS, was completed in 1968 with a primary purpose of flood risk reduction along Swing Creek. Standing at a height of 48 feet and a length of 1720 feet, the dam has a storage capacity of 3526.65 acre-feet and serves a drainage area of 8.23 square miles.
With a low hazard potential and a moderate risk assessment, Frd No E-7 is regulated and inspected by the Kansas Department of Agriculture to ensure its structural integrity and functionality. The dam features an uncontrolled spillway with a width of 40 feet, allowing for a maximum discharge of 450 cubic feet per second. While the condition assessment is currently not rated, the dam's risk management measures are not specified, and there is no Emergency Action Plan (EAP) in place.
Water resource and climate enthusiasts interested in the infrastructure and management of dams will find Frd No E-7 an intriguing subject. As a crucial component in mitigating flood risks in the region, this dam plays a vital role in protecting the surrounding communities and environment. Its design, construction, and regulatory oversight provide valuable insights into the intersection of water resource management, public safety, and environmental stewardship in Kansas.

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.
