Summary
Constructed in 1971 by the USDA NRCS, this buttress dam stands at a height of 45 feet and serves the primary purpose of flood risk reduction along the No Branch Verdigris River. With a maximum storage capacity of 1160 acre-feet and a normal storage of 158 acre-feet, Frd No 4-1 plays a crucial role in managing water flow and mitigating potential flood hazards in the area.
Managed by the Kansas Department of Agriculture, this dam is regulated, permitted, and inspected by state authorities to ensure its structural integrity and operational efficiency. Despite being classified as having a low hazard potential, the condition of Frd No 4-1 is currently not rated, highlighting the need for ongoing monitoring and maintenance. With its strategic location and design, this dam stands as a valuable asset in water resource management and climate resilience efforts in the region, demonstrating the importance of sound infrastructure for safeguarding communities against natural disasters.
As part of the flood risk reduction system in the area, Frd No 4-1 plays a crucial role in protecting nearby communities from potential inundation events. With its sturdy buttress design and efficient operation, this dam serves as a critical piece of infrastructure in the overall water management strategy for the No Branch Verdigris River watershed. Moving forward, continued monitoring, assessment, and maintenance of Frd No 4-1 will be essential to ensure its long-term effectiveness in safeguarding the local area from flood risks and promoting sustainable water resource management practices.

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.
