Tuttle Creek Dam, also known as Tuttle Creek Lake, is a federally owned structure located in Manhattan, Kansas, along the Big Blue River. Completed in 1962, this rockfill dam stands at a structural height of 157 feet and has a total length of 7,500 feet. The dam serves primarily for flood risk reduction, with additional purposes including fish and wildlife habitat, recreation, and navigation.

With a maximum storage capacity of 2,257,000 acre-feet and a normal storage level of 335,100 acre-feet, Tuttle Creek Dam plays a crucial role in managing water resources in the region. The dam's controlled spillway, with a width of 839 feet, helps regulate water levels during high flow events. Despite being categorized with a high hazard potential, the US Army Corps of Engineers actively manages dam-related flood risks through regular inspections, maintenance, and collaboration with local emergency managers to ensure the safety and integrity of the structure.

As a key component of the water infrastructure in Kansas, Tuttle Creek Dam showcases the importance of effective risk management and emergency preparedness in safeguarding communities against potential flooding events. With ongoing monitoring and strategic interventions in place, the dam continues to fulfill its critical role in protecting downstream areas and supporting various water-related activities in the region.
