Summary

Completed in 1966, this earth dam stands at a height of 27 feet and serves the primary purpose of flood risk reduction. Its storage capacity reaches 1451 acre-feet, with a normal storage level of 96.5 acre-feet and a surface area of 3.75 acres.

Situated along De Haas Creek in Butler County, Kansas, Frd No 8 plays a crucial role in fire protection, stock maintenance, flood risk reduction, and recreational activities for the local community. Despite its low hazard potential and moderate risk assessment rating, the dam has not undergone a condition assessment and is currently not rated for its structural condition. While it lacks outlet gates and a comprehensive Emergency Action Plan, Frd No 8 remains a vital resource for water management and climate resilience in the region.

As water resource and climate enthusiasts, understanding the history, design, and purpose of Frd No 8 sheds light on the intricate balance between human infrastructure and natural ecosystems. The dam's presence highlights the ongoing efforts to mitigate flood risks, enhance water storage capacity, and maintain the ecological integrity of De Haas Creek. By recognizing the importance of structures like Frd No 8, we can contribute to sustainable water resource management and climate adaptation strategies in our communities.

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.
