Bear Lake
Bear Lake is an earth dam located in Leavenworth County, Kansas. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Bear Lake
The primary purpose of Bear Lake is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Bear Lake Home Association (private). It impounds the Kaw Creek-tr near Mahon.
The dam stands 48 feet tall and stretches 900 feet across, creates a reservoir covering 63 acres, has a maximum storage capacity of 1,738 acre-feet, and collects water from a drainage area of 4 square miles.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 12/14/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
At 48 feet, this dam is taller than 92% of dams nationwide.
