Summary

Built in 1996 with a primary purpose of recreation, this picturesque lake offers a surface area of 83.1 acres and a maximum storage capacity of 1838 acre-feet. The dam stands at 38 feet high and spans 700 feet in length, with a spillway width of 125 feet. Antelope Lake is situated on Antelope Creek and is regulated by the Kansas Department of Agriculture, ensuring proper inspection and enforcement measures are in place to maintain its safety and function.

The dam's design, attributed to Welt and Wagner, features a buttress core type with an unlisted/unknown foundation. Despite being categorized as having a low hazard potential, Antelope Lake has not been rated for its condition assessment. The reservoir offers a serene escape for water resource and climate enthusiasts, with opportunities for boating, fishing, and other recreational activities. With its tranquil setting and proximity to nature, Antelope Lake serves as a peaceful retreat in the heart of Kansas, welcoming visitors to enjoy the beauty and tranquility of this man-made oasis.

For those interested in exploring the intersection of water resource management and climate resilience, Antelope Lake presents a fascinating case study of private ownership and state regulation in maintaining a recreational water source. With its strategic location in Graham County and its role in supporting local eco-tourism, this reservoir exemplifies the importance of balancing environmental stewardship with human enjoyment. As enthusiasts continue to appreciate and study the dynamics of Antelope Lake, its impact on the surrounding ecosystem and its resilience in the face of changing climate patterns will undoubtedly be areas of ongoing interest and exploration.

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.
