Otis Creek Dam (Mpd No W-7), also known as Fall River Watershed Dam W-7, is a vital structure located in Greenwood County, Kansas. Built in 1971 by A&E and USDA SCS, this earth dam stands at a height of 86 feet and has a structural height of 94 feet, serving the primary purpose of flood risk reduction in the region. With a maximum storage capacity of 13,300 acre-feet and a normal storage of 5,850 acre-feet, the dam plays a crucial role in water resource management for the Otis Creek watershed.

Managed by the local government and regulated by the Kansas Department of Agriculture, Otis Creek Dam is equipped with an uncontrolled spillway with a width of 100 feet to manage potential overflow. The dam's hazard potential is rated as high, with a fair condition assessment as of the last inspection in April 2018. Despite its moderate risk assessment, the dam's emergency action plan and risk management measures are currently unspecified, highlighting the need for continued monitoring and preparedness to ensure the safety and integrity of the structure for both flood risk reduction and water supply purposes. Enthusiasts of water resources and climate management will find Otis Creek Dam to be a fascinating case study in dam engineering and regulatory oversight within the state of Kansas.
