Summary
Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam stands at a height of 55 feet and was completed in 1968 to primarily reduce flood risk in the area. With a storage capacity of 3,667.15 acre-feet and a drainage area of 9.99 square miles, this dam plays a crucial role in managing water flow in the Pool Creek watershed.
Managed by the USDA NRCS and designed by the Natural Resources Conservation Service, Frd No 8-23 has a spillway width of 270 feet and a maximum discharge capacity of 15,700 cubic feet per second. Despite being classified as having a low hazard potential, the dam is rated as having moderate risk due to its age and condition. The structure has not been rated for its current condition, and there are no emergency action plans or inundation maps prepared for this dam, highlighting the need for further assessment and risk management measures to ensure its long-term safety and functionality. Water resource and climate enthusiasts will find Frd No 8-23 to be an intriguing example of flood risk reduction infrastructure in a scenic Kansas landscape.

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.
