Summary
Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam was completed in 1979 and serves primarily for flood risk reduction purposes. With a dam height of 30 feet and a hydraulic height of 28 feet, Frd No 9 has a storage capacity of 4232 acre-feet and a drainage area of 7.51 square miles.
This dam, designed by the USDA NRCS, plays a significant role in mitigating flood hazards in the region with a low hazard potential rating. The structure spans 3790 feet in length and has a spillway width of 200 feet. Despite being uncontrolled, the dam has a maximum discharge capacity of 4398 cubic feet per second. While the condition assessment is currently not rated, the risk assessment for Frd No 9 is moderate, indicating the importance of ongoing monitoring and maintenance to ensure its effectiveness in flood risk reduction.
Overall, Frd No 9 stands as a vital component of water resource management in Marion County, Kansas. With its strategic location along the Whitewater River, this earth dam serves to protect the surrounding area from flooding events, highlighting the critical role of infrastructure in climate resilience efforts. As water resource and climate enthusiasts, understanding the design, purpose, and condition of structures like Frd No 9 is essential for promoting sustainable water management practices and ensuring the safety and well-being of communities in flood-prone regions.

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.
