Summary
Built in 1962 by the USDA NRCS, this earth dam stands at a height of 41 feet and serves the primary purpose of flood risk reduction along the Hoover Branch river or stream. With a storage capacity of 4537 acre-feet and a drainage area of 4.89 square miles, Dd No 7 plays a crucial role in managing water flow and mitigating potential hazards.
Despite its fair condition assessment and a high hazard potential, Dd No 7 is regularly inspected by the Kansas Department of Agriculture to ensure its structural integrity and safety. The dam features an uncontrolled spillway with a width of 200 feet, capable of handling a maximum discharge of 12,830 cubic feet per second. Its moderate risk assessment rating indicates the need for ongoing risk management measures to safeguard against any potential emergencies. Water resource and climate enthusiasts can appreciate the significance of Dd No 7 in protecting the surrounding area from flooding and contribute to the sustainable management of water resources in the region.

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.
