Summary
Owned by the local government, this structure stands at a height of 33 feet and spans 875 feet in length, with a storage capacity of 328 acre-feet and a maximum discharge of 2110 cubic feet per second. Despite its low hazard potential, the dam has not been rated for its condition, and its last inspection took place in 2002.
Managed by the Kansas Department of Agriculture, Dd No 27 serves as a crucial component of the flood control infrastructure in Pottawatomie County. With a surface area of 7.11 acres and a drainage area of 1.36 square miles, this earth dam plays a significant role in debris control and flood risk reduction efforts in the region. While the dam's risk assessment indicates a moderate level of risk, the structure has not been assigned a Dam Safety Action Classification (DSAC) date, and its emergency action plan (EAP) status remains unspecified.
As water resource and climate enthusiasts, it is important to monitor the condition and maintenance of Dd No 27 to ensure its continued effectiveness in mitigating flood risks and protecting the surrounding communities. With its strategic location and essential role in the local flood control system, this earth dam represents a critical asset in safeguarding lives and properties against the impacts of extreme weather events and rising water levels. By staying informed and advocating for proper inspection and maintenance protocols, stakeholders can help sustain the resilience of Dd No 27 for years to come.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
