Summary
With a height of 107 feet and a hydraulic height of 90 feet, this buttress dam serves a primary purpose of 'Other' and has a normal storage capacity of 3250 acre-feet. The dam's reservoir covers a surface area of 122.5 acres and has a drainage area of 0.63 square miles, with a maximum discharge capacity of 2970 cubic feet per second.
Owned privately, the Jeffrey Energy Center- Makeup Dam is regulated by the Kansas Department of Agriculture and undergoes regular state inspections to ensure its safety and functionality. The dam has a high hazard potential but has been assessed to be in satisfactory condition. Although it does not have a designated spillway type, it is equipped with outlet gates. The dam is situated along the Kansas River and is part of the Kansas City District, with Congressman Roger W. Marshall representing the area.
Overall, the Jeffrey Energy Center- Makeup Dam plays a crucial role in water resource management and climate resilience in Pottawatomie County, Kansas. With its significant storage capacity and strategic location, it helps mitigate flood risks and ensures a stable water supply for the surrounding area. As a key piece of infrastructure, the dam underscores the importance of proactive monitoring and maintenance to uphold its safety and operational effectiveness in the face of changing environmental conditions.

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.
