Summary

Constructed in 1996, this earth-type dam stands at 26 feet high and spans 1200 feet in length, serving primarily for flood risk reduction and debris control purposes in the region. With a storage capacity of 293.43 acre-feet and a surface area of 8.49 acres, the dam plays a crucial role in managing water resources in the area.

Managed by the Kansas Department of Agriculture and regulated by the state, Dd No 248 has a low hazard potential and a moderate risk assessment rating. Despite not having been rated for its condition assessment, the dam is inspected regularly by state authorities to ensure its structural integrity and operational efficiency. With no outlet gates and an uncontrolled spillway type, the dam is designed to handle potential flood events effectively, mitigating risks for downstream communities and the environment.

With its location in Wabaunsee County and proximity to the Kansas City District, Dd No 248 is a key infrastructure asset for the region. As water resource and climate enthusiasts, understanding the design, purpose, and management of dams like Dd No 248 is essential for ensuring sustainable water management practices and resilience to climate change impacts in the area.

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.
