Summary

Built in 1968 by the USDA NRCS, this dam primarily serves the purpose of flood risk reduction along the Hickory Creek-TR river or stream. With a structural height of 36 feet and a length of 1200 feet, Frd No 23 has a storage capacity of 649.1 acre-feet and covers a surface area of 11.71 acres.

Despite being classified as having a low hazard potential, Frd No 23 is subject to state regulation, inspection, and enforcement by the Kansas Department of Agriculture. The dam features an uncontrolled spillway with a width of 40 feet and a maximum discharge capacity of 1635 cubic feet per second. While the condition assessment is currently listed as "Not Rated," the risk assessment for this dam is determined to be moderate, with a DSAC assigned date yet to be specified.

In conclusion, Frd No 23 plays a crucial role in mitigating flood risks in the region and is monitored for compliance with state regulations and safety standards. As a key infrastructure project designed to protect against potential flooding events, the dam serves as a vital asset for water resource management and climate resilience efforts in Butler County, Kansas.

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.
