Milford Lake is a 15,700-acre U.S. Army Corps of Engineers reservoir on the Republican River in Cloud, Clay, and Ottawa counties in north-central Kansas — the largest lake in Kansas and the primary recreational boating destination for the Junction City and Manhattan corridor in the Flint Hills region. The lake sits approximately 5 miles north of Junction City and adjacent to Fort Riley — the U.S. Army installation that gives the Milford Lake area a consistent military and civilian boating population from the Manhatan, Junction City, and Salina communities. The Republican River arm and the lake’s extensive cove structure produce walleye, largemouth and smallmouth bass, crappie, white bass, and channel catfish fishing managed by the Kansas Department of Wildlife and Parks. Milford State Park on the lake’s eastern shore provides marina facilities, boat launch access, and camping serving the north-central Kansas boating community. Find Boat Services lists verified boat repair, motor service, electronics installation, trailer repair, and winterization providers serving Milford Lake within 35 miles across Cloud, Clay, Ottawa, and Geary counties.
