Lake Jacomo is a 970-acre freshwater reservoir inside Fleming Park — a 7,809-acre county park near Blue Springs, Missouri in Jackson County. The reservoir was built between 1952 and 1959 and officially opened May 30, 1959. The project originated when Harry S. Truman, then Presiding Judge of Jackson County, ordered a study in 1932, two decades before voters approved the enabling bond. Its 19-mile shoreline now hosts the largest boat-rental marina in the Kansas City metropolitan area.1
