Summary
Completed in 1989, this dam stands at 30 feet high, with a length of 1500 feet and a storage capacity of 1220 acre-feet. The dam is situated on Doyle Creek-TR and serves to protect the surrounding area from potential flooding events.
Despite its low hazard potential, Dd No 8 is regulated and inspected by the Kansas Department of Agriculture, ensuring its structural integrity and functionality. With a moderate risk assessment rating of 3, this dam plays a crucial role in managing water resources in the region. While the dam itself does not have outlet gates or locks, its uncontrolled spillway with a width of 140 feet helps manage excess water flow during periods of high discharge.
Overall, Dd No 8 serves as an important infrastructure asset for flood risk reduction in Harvey County, Kansas. With its strategic location and design, this dam provides essential protection for the community and surrounding area, highlighting the critical role of water resource management in mitigating the impacts of climate-related events.

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.
