Summary
Built in 1995, this earth dam stands at a height of 32 feet and has a length of 500 feet. It serves multiple purposes including fire protection, stock or small fish pond, grade stabilization, and recreation. With a normal storage capacity of 50 acre-feet and a maximum storage of 121 acre-feet, Farnan covers a surface area of 6 acres and drains an area of 332.8 square miles.
The dam on Farnan is designed with a stone core and a soil foundation, and it features an uncontrolled spillway with a width of 50 feet. Despite having a low hazard potential, the risk assessment for Farnan is moderate (3), highlighting the need for careful monitoring and management. While the condition assessment is currently not rated, the dam has not undergone recent inspections or evaluations to determine its structural integrity.
As a water resource and climate enthusiast, Farnan offers an intriguing case study in dam infrastructure and management. Its multiple purposes and moderate risk level present unique challenges for ensuring its safety and functionality. With its location on the TR-Platte River and under the jurisdiction of the Kansas City District, Farnan serves as a valuable asset for both local community needs and environmental considerations.

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.
