Summary
Constructed in 1987, this earth dam stands at a height of 28 feet and stretches 1400 feet in length, with a storage capacity of 587.8 acre-feet. The dam serves a primary purpose of flood risk reduction and is regulated by the Kansas Dept. of Agriculture, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite its low hazard potential, Dd No 7 is considered to have a moderate risk level, rated at a 3 on the risk assessment scale. The dam is equipped with an uncontrolled spillway with a width of 100 feet, capable of handling a maximum discharge of 2470 cubic feet per second. While the condition of the dam is currently not rated, it is designed to withstand potential flood events and protect the surrounding area from water-related emergencies. Enthusiasts of water resources and climate will find Dd No 7 to be an essential piece of infrastructure in managing flood risks and ensuring the safety of the community in Harvey County, 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.
