Summary

It serves as a Rockfill dam primarily designed for Flood Risk Reduction, with a height of 8.8 feet and a storage capacity of 110.8 acre-feet. The dam spans 800 feet in length, covering a surface area of 6.71 acres and draining an area of 0.86 square miles. Despite its low Hazard Potential, Sediment Pond 5 has not been officially rated for its condition, and no inspections or assessments have been conducted to date.

Designed by ALAN BOWLES, P.E., Sediment Pond 5 does not fall under state jurisdiction, permitting, or inspection, and is not regulated by any state agency. The structure has no associated structures and lacks specific features such as spillways or outlet gates. While the dam has not been modified since its completion, there is limited information on its operational history or emergency preparedness. Although the risk and management measures for Sediment Pond 5 remain unidentified, its strategic location and flood control purpose underscore its importance in the region's water resource management and climate resilience efforts.

With its unique design and purpose, Sediment Pond 5 stands as a testament to private ownership's role in flood risk reduction within the Kansas landscape. As water resource and climate enthusiasts explore the potential of such structures in mitigating natural disasters and promoting environmental sustainability, Sediment Pond 5 serves as a noteworthy case study in the intersection of engineering, private ownership, and public safety. While its condition assessment and risk management aspects warrant further attention, the dam's existence highlights the ongoing need for proactive measures in safeguarding communities against water-related hazards 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.
