Summary

This earth dam, primarily designed for flood risk reduction, stands at a height of 30.5 feet and stretches 800 feet in length, with a storage capacity of 651.5 acre-feet. The dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections, with a hazard potential rated as significant and a moderate risk assessment score of 3.

Despite the dam being classified as not rated in terms of condition assessment, it remains a crucial structure in managing flood risk in the area. The dam's uncontrolled spillway, with a width of 70 feet, helps manage excess water flow during heavy rainfall events. While the dam currently does not have outlet gates, it serves as a vital piece of infrastructure in protecting the surrounding community from potential flooding. With a notable inspection frequency of 5 years, the dam is closely monitored to ensure its continued effectiveness in flood risk reduction.

Overall, Dd No 108 (Huffman) plays a pivotal role in safeguarding the local area from the impacts of flooding along the 142 Mile Creek. With a focus on flood risk reduction as its primary purpose, the dam's design and construction are vital in managing water flow and storage capacity during extreme weather events. As a state-regulated structure, the dam undergoes regular inspections and is equipped with a significant hazard potential rating, highlighting its importance in ensuring the safety and resilience of the surrounding community in the face of climate-related challenges.

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.
