Summary
Managed by the Local Government and regulated by the Kansas Department of Agriculture, this structure stands at a height of 30 feet and spans 450 feet in length, with a storage capacity of 88.8 acre-feet. Despite its low hazard potential, the dam plays a crucial role in mitigating flood risks and protecting the surrounding area.
Located in the Tulda District and designed by the USDA NRCS, Dd No Iv-8's structure includes an uncontrolled spillway and a surface area of 3.1 acres, serving a drainage area of 0.27 square miles. Although its condition assessment is currently listed as "Not Rated," the dam is subject to inspection, enforcement, and permitting by state regulatory agencies. With a moderate risk assessment rating, it is essential for water resource and climate enthusiasts to monitor the ongoing management and maintenance of this key flood control infrastructure in Kansas.
As an integral part of the flood risk reduction system in Bourbon County, Dd No Iv-8 stands as a testament to the collaborative efforts of local government and state agencies in safeguarding the community from potential water-related hazards. With its strategic design and operational protocols in place, this earth dam continues to play a crucial role in water resource management and climate resilience efforts in the region.

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.
