Summary
Built in 1971 by the USDA NRCS, this earth dam stands at a height of 33 feet and serves primarily for flood risk reduction along the Black Vermillion River. With a storage capacity of 392 acre-feet and a surface area of 17.02 acres, the dam plays a crucial role in safeguarding the surrounding area from potential flooding events.
Managed by the Kansas Department of Agriculture, Frd No 30 is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and operational effectiveness. Despite being classified as having a low hazard potential, the dam is rated as moderate in terms of risk, highlighting the importance of ongoing monitoring and risk management measures. With a spillway width of 40 feet and a drainage area of 1.12 square miles, the dam is equipped to handle controlled releases during periods of high water flow to mitigate downstream impacts.
The location of Frd No 30 in Marshall County, Kansas, demonstrates the collaborative efforts between federal and state agencies in overseeing the safety and functionality of water resource infrastructure. As part of the Kansas City District, the dam serves as a critical component in the region's flood protection system, showcasing the significance of proactive maintenance and emergency preparedness in safeguarding communities and ecosystems from the impacts of extreme weather events and climate variability.

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.
