Summary
Completed in 1959, this dam stands at a height of 34 feet and serves the primary purpose of flood risk reduction along Grasshopper Creek. With a normal storage capacity of 14.3 acre-feet and a drainage area of 3.16 square miles, Dd No Vii plays a crucial role in mitigating potential flood hazards in the area.
Managed by the Kansas Department of Agriculture, Dd No Vii is regulated, permitted, inspected, and enforced by state agencies to ensure its structural integrity and functionality. With a low hazard potential and moderate risk assessment rating, this dam provides essential water resource management and flood control benefits to the surrounding community. The dam features an uncontrolled spillway with a width of 170 feet and has not been modified since its construction.
As a key structure in the flood risk reduction efforts along Grasshopper Creek, Dd No Vii is a vital component of the water resource infrastructure in Brown County, Kansas. With its designed by the USDA NRCS and oversight by state agencies, this earth dam continues to provide valuable protection against flooding events while maintaining a low hazard potential. Enthusiasts of water resources and climate resilience will appreciate the strategic importance of Dd No Vii in safeguarding the local community from potential water-related risks.

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.
