Dam No 2-6, also known as Timber Hill Lake, is a local government-owned structure located in Caney, Kansas. This earth dam, with a height of 59 feet and a hydraulic height of 51 feet, was completed in 1966 for the primary purpose of flood risk reduction. Its normal storage capacity is 854 acre-feet, providing water supply benefits in addition to flood protection for the surrounding area. The dam is regulated and inspected by the Kansas Department of Agriculture, ensuring its safety and compliance with state regulations.

Situated on Otter Creek, Dam No 2-6 spans 1400 feet in length and covers a surface area of 90.34 acres. With a drainage area of 6.03 square miles, the dam plays a crucial role in managing water flow and mitigating flood risks in the region. Despite its high hazard potential, the dam's condition assessment is currently not rated, highlighting the importance of regular inspections and maintenance to ensure its structural integrity and safety. Although no spillway type is specified, the dam features a spillway width of 130 feet for controlled water release during high flow events.

With its strategic location and significant water management capabilities, Dam No 2-6 serves as a vital infrastructure asset for flood risk reduction and water supply in Chautauqua County, Kansas. Owned and operated by the local government, this earth dam represents a key component of the region's water resource management system. As climate change impacts continue to pose challenges to water availability and flood control, the importance of maintaining and monitoring dams like Timber Hill Lake becomes increasingly crucial in safeguarding communities and ecosystems against water-related risks.
