Bear Lake, also known as Little Kaw Creek Detention Dam, is a private water resource in Kansas, specifically located in Leavenworth County. Managed by the USDA NRCS, this Earth dam stands at a height of 41 feet and serves the primary purpose of flood risk reduction along the Kaw Creek-TR river or stream. With a normal storage capacity of 610.7 acre-feet and a maximum discharge of 4620 cubic feet per second, Bear Lake plays a crucial role in managing water flow in the region.

This dam, with a structural height of 48 feet and a length of 900 feet, has a high hazard potential but is currently assessed to be in fair condition. Despite being privately owned, it is subject to state regulation and inspection by the Kansas Department of Agriculture. The last inspection date was in December 2017, with a frequency of every 3 years. While the dam does not have outlet gates or associated structures, it serves as a vital asset for flood control and water management in the area, contributing to the overall resilience of the local water resources and climate.

Bear Lake's strategic location in Mahon, Kansas, and its significant storage capacity of 1738.1 acre-feet make it a key infrastructure for mitigating flood risks and ensuring water security in the region. With its hydraulic height of 39 feet and surface area of 63.1 acres, the dam plays a critical role in regulating water levels and protecting downstream communities. As climate change continues to impact water resources, Bear Lake stands as a vital asset for maintaining the balance between water supply, flood control, and environmental sustainability in Leavenworth County.
