Longview Dam, also known as Longview Lake, is a federal-owned structure located in Kansas City, Missouri, along the Little Blue River. Completed in 1985, this earth dam stands at a hydraulic height of 120 feet and a structural height of 125 feet, with a length of 1900 feet and a dam volume of 1,943,000 cubic yards. The dam serves multiple purposes, including flood risk reduction, fish and wildlife pond, recreation, and water supply, with a normal storage capacity of 22,100 acre-feet.

Managed by the US Army Corps of Engineers, Longview Dam has a high hazard potential and is regularly monitored for its condition and risk assessment. The dam's emergency action plan, last revised in January 2021, meets guidelines, and inundation maps are prepared for potential flood scenarios. The USACE actively engages with local emergency managers and the public to raise awareness of the dam and ensure readiness for any dam-related emergencies.

In times of severe weather events or increased water levels, the dam may release water to manage downstream or relieve pressure to maintain structural integrity. Risk management measures implemented by the USACE include ongoing monitoring, prioritizing activities to reduce risks, and collaborating with local authorities to develop emergency and evacuation plans. Overall, Longview Dam plays a vital role in flood risk reduction and water management in the region, with continuous efforts to enhance its safety and effectiveness.
