Lake Koshkonong is a popular fishing destination located in southern Wisconsin, primarily in Rock County. As one of the largest inland lakes in the state, it offers a wide range of fishing opportunities for anglers of all skill levels.

Largemouth and smallmouth bass are highly sought-after species in Lake Koshkonong. Anglers can target these bass species using a variety of techniques, including casting soft plastics, working topwater lures, or trolling with crankbaits. The lake's extensive shoreline and submerged structures provide excellent habitat for bass, making it an ideal spot for bass fishing enthusiasts.

Walleye is another prized fish species found in Lake Koshkonong. Known for their elusive nature, walleye can be challenging to catch but rewarding for those who are successful. Trolling with crankbaits, jigging with live bait, or using bottom bouncers are common techniques employed by anglers targeting walleye in the lake.

Muskie, also known as muskellunge, is a popular gamefish species in Lake Koshkonong. These large and aggressive predators offer anglers an exciting challenge. Casting large artificial baits, such as bucktail spinners or jerkbaits, along weed beds, and rock structures can entice muskie strikes. Proper equipment and handling techniques are important when targeting these powerful fish.

Lake Koshkonong is also known for its panfish species, including white crappie, black crappie, channel catfish, northern pike, yellow perch, and bluegill. These species provide opportunities for anglers seeking a relaxing day of fishing and a tasty meal. Crappie and bluegill are commonly targeted by anglers using small jigs, live bait, or bobber rigs.
