Summary
With a dam height of 32.5 feet and a length of 1460 feet, this structure provides storage for up to 579 acre-feet of water and serves a drainage area of 1.6 square miles. Despite being classified as having a low hazard potential, the dam is associated with a moderate risk level due to its location and function.
Managed by the Kansas Department of Agriculture and regulated by the state, Frd No 7 does not have any associated structures or outlet gates. The spillway, with a width of 40 feet, is uncontrolled, allowing for a maximum discharge of 1397.3 cubic feet per second. While the dam's condition has not been formally rated, it is subject to regular state inspections and enforcement to ensure its continued safety and effectiveness in mitigating flood risks in the region.
Although Frd No 7 has not been modified in recent years and lacks an emergency action plan, it remains a vital asset in the local flood control infrastructure. With its strategic location and design, this dam plays a crucial role in protecting the surrounding area from potential flooding events. Climate and water resource enthusiasts will find Frd No 7 to be an intriguing example of how engineering interventions can help manage water-related risks in vulnerable regions like Lyon County.

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.
