Hillsdale Lake is a 4,580-acre U.S. Army Corps of Engineers reservoir on the Big Bull Creek in Miami County in eastern Kansas — the primary recreational boating destination for the Kansas City metropolitan area’s southern reach and the most accessible large reservoir to the Johnson County and Overland Park corridor in northeastern Kansas. The lake sits approximately 35 miles south of downtown Kansas City and 25 miles southwest of Overland Park, drawing consistent boating traffic from the Kansas City metro southern suburbs throughout the open water season. The Big Bull Creek arm and the lake’s cove structure produce largemouth bass, crappie, walleye, white bass, and channel catfish fishing managed by the Kansas Department of Wildlife and Parks. Hillsdale State Park on the lake’s eastern shore provides marina facilities, boat launch access, and camping serving the Kansas City metro boating community. Find Boat Services lists verified boat repair, motor service, electronics installation, trailer repair, and storage providers serving Hillsdale Lake within 25 miles across Miami and Johnson counties. The Kansas City metro proximity gives Hillsdale boaters access to the largest concentration of marine service providers in eastern Kansas and the greater Kansas City corridor.
