$57 million was appropriated for the dam and lake project. Groundbreaking on the dam occurred May 4, 1963. Filling of the reservoir began August 1, 1970. The lake was officially dedicated September 12, 1970. The dam is 3,025 feet (922.0 m) long and 108 feet (32.9 m) tall with normal pool height 17 feet (5.2 m) below the top.

Bordering the lake are two state parks: Wolf Creek State Park and Eagle Creek State Park; and five federal campgrounds including Coon Creek, Opossum Creek, Lithia Springs, Lone Point, and Forest (Bo) Woods. There is also Wilburn Creek and Whitley Creek Recreational Area. Lake Shelbyville's shoreline is heavily wooded and subject to severe erosion. Man-made beaches are located at Dam West (Shelbyville), Wilborn Creek, Wolf Creek State Park, and Sullivan Beach. Aside from the main channel of the lake are many coves, perfect for fishing. The lake is deeper than other major lakes in Illinois, so it is popular with boaters during the summer.

There are full-service marinas, resorts and campgrounds on the lake. There are three full service marinas in business: Findlay, Lithia Springs, and Sullivan Marina. Findlay Marina is located north of Marker 5 just past the bridge on the west side of the lake. Sullivan Marina and Campground is located 4 miles south of Sullivan and includes hotel suites. Lithia Springs Marina is located on the southern end of Lake Shelbvyille. Lithia Marina is a full-service marina offering covered and open slip rental with free in-slip pump outs, Wi-Fi, 6 full service fuel pumps including pump out services and water fill ups, a Subway restaurant, a ship store with bait, fishing licenses, boat rental, clothing, ice, sundries, beer and a full service shop with 2 full time certified mechanics including haul out and launch services.
