Frd No 9 Reservoir Report

Last Updated: December 5, 2025

Frd No 9, located in Mitchell, Kansas, was completed in 1980 by the USDA NRCS for the primary purpose of flood risk reduction along the WEST BRANCH THIRD CREEK-TR.

Summary

This earth dam has a height of 32.5 feet and a length of 860 feet, providing a storage capacity of 442.32 acre-feet. Despite being classified as a low hazard potential structure, it is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture, ensuring its safety and functionality.

The dam's moderate risk assessment indicates the need for proactive risk management measures, though its condition remains unrated. The uncontrolled spillway with a width of 80 feet allows for a maximum discharge of 2214 cubic feet per second, serving a drainage area of 1.22 square miles. While no outlet gates or associated structures are present, Frd No 9 covers a surface area of 9.19 acres and offers essential flood protection for the local community.

With Roger W. Marshall (R) as the representative for the Kansas City District, Frd No 9 plays a crucial role in mitigating flood risks and safeguarding the surrounding area from potential inundation events. As a vital infrastructure project supported by the Natural Resources Conservation Service, this dam stands as a testament to proactive water resource management and climate resilience efforts in Kansas.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
