Summary
Built in 1969 by the USDA NRCS, this earth dam stands at a height of 34 feet and serves the primary purpose of flood risk reduction along the IRISH CREEK-TR river. With a storage capacity of 999.71 acre-feet and a surface area of 25.23 acres, this dam plays a vital role in protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the Kansas Department of Agriculture, Frd No 71 has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. Despite its moderate risk level, this dam has not undergone a recent inspection and its emergency action plan status is unknown. With its uncontrolled spillway and lack of outlet gates, it is clear that continued monitoring and maintenance of this structure are essential to ensure its effectiveness in mitigating flood risks in the region.
As a water resource and climate enthusiast, understanding the importance of dams like Frd No 71 in managing and protecting our natural environment is crucial. With its history of service in flood risk reduction and its strategic location in Marshall County, Kansas, this dam serves as a key asset in safeguarding communities and infrastructure from the impacts of extreme weather events. It is imperative that ongoing assessments and maintenance efforts are carried out to uphold the safety and functionality of Frd No 71 for years to come.

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.
