Summary

for flood risk reduction on Cedar Creek. Completed in 1994, this dam has a height of 27 feet and a length of 1450 feet, providing a storage capacity of 810 acre-feet and a normal storage of 94.8 acre-feet. With a surface area of 22.5 acres and a drainage area of 1.94 square miles, Dd No 10 plays a crucial role in managing the flow of water and reducing the risk of flooding in the area.

Managed by the Kansas Department of Agriculture and regulated at the state level, Dd No 10 has a low hazard potential and is currently rated as "Not Rated" for its condition assessment. While it does not have outlet gates, the dam features an uncontrolled spillway with a width of 100 feet to manage excess water flow. With a moderate risk assessment rating of 3, Dd No 10 serves as a key piece of infrastructure in the region's water resource and climate management efforts, ensuring the safety and protection of surrounding communities from potential flooding events.

Overall, Dd No 10's strategic location and design make it a vital asset for flood risk reduction in Woodson County. With its important role in managing water flow and storage capacity, this dam provides essential protection and peace of mind for local residents and businesses. As climate change continues to impact weather patterns and increase the frequency of extreme weather events, the significance of structures like Dd No 10 in safeguarding against flooding cannot be overstated for water resource and climate enthusiasts alike.

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.
