Summary

The dam's primary purpose is flood risk reduction, with a height of 30.5 feet and a storage capacity of 332.7 acre-feet. Situated on Bartlett Creek-TR, the dam has a drainage area of 1.16 square miles and a spillway width of 40 feet. With a low hazard potential and a moderate risk assessment rating, Dd No 109 is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture.

Despite being unlisted in terms of foundations and structural height, Dd No 109 has a normalized storage capacity of 46.5 acre-feet and a surface area of 9.4 acres. Although the dam has not been rated for its condition assessment, it meets guidelines in terms of emergency action preparedness. With a maximum discharge of 1110 cubic feet per second and no associated locks or outlet gates, the dam poses a low hazard potential to the surrounding area. The risk management measures and risk characterization summary for Dd No 109 are currently unspecified.

Located in a region represented by Congressman Roger W. Marshall, Dd No 109 serves as a vital infrastructure for flood risk reduction in Pottawatomie, Kansas. With its controlled spillway and lack of associated structures, the dam plays a crucial role in managing water resources and potential climate-related challenges in the area. Water resource and climate enthusiasts can appreciate the significance of Dd No 109 in safeguarding the local community against flooding events and ensuring the sustainable management of water in the region.

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.
