Summary
Built in 1969 by USDA NRCS for Flood Risk Reduction along the Irish Creek-TR, this 26-foot high structure spans 710 feet and provides a storage capacity of 106.28 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam remains in "Not Rated" condition as of the last assessment.
Located in Marshall County, Kansas, Frd No 69 serves as a crucial flood risk mitigation tool for the community. With a normal storage capacity of 21 acre-feet and a surface area of 4.07 acres, this dam plays a vital role in protecting the area from potential flooding events. While it currently lacks a formal emergency action plan and detailed risk management measures, the dam's design and construction by the Natural Resources Conservation Service ensures its structural integrity and effectiveness in flood control.
Managed by local government authorities, Frd No 69 is not regulated, permitted, or inspected by state agencies. However, its strategic location and design features, such as an uncontrolled spillway with a width of 40 feet, contribute to its overall functionality and efficiency in flood risk reduction. As water resource and climate enthusiasts continue to monitor and evaluate the dam's performance, its importance in safeguarding the community against flooding events remains paramount.

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.
