Summary

Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam stands at a height of 39.7 feet and was completed in 2005. With a storage capacity of 791 acre-feet and a drainage area of 1.92 square miles, this structure plays a crucial role in protecting the surrounding area from potential flooding events.

Despite being classified as having a high hazard potential, Site 8-33 is currently assessed as being in fair condition. With a moderate risk rating of 3, this dam undergoes inspections every 3 years to ensure its structural integrity and functionality. The spillway, with a width of 100 feet, serves as the primary outlet for excess water, allowing for a maximum discharge of 5869 cubic feet per second. While there are no associated locks or gates, this dam continues to play a crucial role in mitigating flood risks in the region.

As water resource and climate enthusiasts, understanding the importance of structures like Site 8-33 is crucial in safeguarding communities and ecosystems from the impacts of extreme weather events. With a focus on flood risk reduction, this dam serves as a key asset in the efforts to manage water resources effectively and protect vulnerable areas from potential inundation. As we continue to monitor and assess the condition of such critical infrastructure, it is essential to prioritize proactive maintenance and risk management measures to ensure the long-term resilience of our water systems in the face of a changing climate.

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.
