Summary

of Agriculture. Completed in 1969, this earth dam stands at 39 feet high with a hydraulic height of 45 feet and a structural height of 50 feet. Its primary purpose is flood risk reduction, serving the Amazon Ditch-TR stream with a drainage area of 2.28 square miles.

With a storage capacity of 1430 acre-feet, Frd No 4 covers a surface area of 12.1 acres and has a maximum discharge rate of 9230 cubic feet per second. The dam's spillway, classified as uncontrolled, features a width of 250 feet. Despite being categorized as having a high hazard potential, the structure is currently in fair condition. Regular inspections occur every three years, with the last assessment conducted in April 2018.

Water resource and climate enthusiasts monitoring Frd No 4 can find valuable information about its design, construction, and regulatory oversight in the provided data. This dam plays a crucial role in mitigating flood risks for the local community in Lakin, Kansas, and its surroundings. With its strategic location and significant storage capacity, Frd No 4 stands as a testament to effective collaboration between federal and state agencies in managing water resources and enhancing climate resilience in the region.

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.
