Between Rockford And Madison Is Wisconsin's Large But Shallow Artificial Lake With Swimming, Fishing, And Boating

In many ways, Wisconsin embodies the essence of the Midwest. The people are friendly, the cost of living is reasonable, and it's often overlooked as a travel destination. While many people may view the Badger State as a place known for its dairy products, there's much more for visitors to discover, from the numerous waterparks of Wisconsin Dells to its underrated cities. But where the state truly shines is in its green spaces, which are perfect for weekend escapes. A key part of the state's natural appeal is its lakes, with more than 15,000 of them scattered throughout and offering visitors plenty of places for boating, fishing, and swimming. One of the state's most underrated lake getaways lies in the south-central region of Wisconsin: Lake Koshkonong.

Situated nearly 55 miles north of Rockford, Illinois, and 37 miles southeast of the state capital of Madison, Lake Koshkonong is a weekend destination for those looking to unplug from the modern world and reconnect with nature. Covering over 10,500 acres and reaching depths of up to 7 feet, Wisconsin's second largest lake offers a wide range of recreational activities, from fishing along its expansive shoreline to boating on its calm waters. The lake wasn't always this big though, as it was enlarged in 1932 when the Indianford Dam was built.

With such a large footprint, Lake Koshkonong is an angler's playground. The lake is shallow, which means that, once the weather warms up, water temperatures rise quickly, and fish become more active as their food source is abundant. Because of this, Lake Koshkonong (or "Kosh" as the locals call it) hosts a wide variety of fish species. As with other lakes around the state, walleye is the dominant catch, as the state's Department of Natural Resources notes that it is among the most prized game fish for local anglers. While walleye is the top fish here, the lake is home to a variety of other fish species, including northern pike and muskie. 

Outside of fishing, boating is another popular activity at Lake Koshkonong. The lake has four boat launches: Royce-Dallman Park, Newville, Glen Oaks Beach, and Indianford County Park. For those looking to paddle, but who don't own their own gear, the towns that surround the lake offer rentals. While on the water, boaters and paddlers can explore the lake's diverse ecosystem, including wetlands that support waterfowl like the white pelican and sandhill cranes. Because of its shallowness, paddlers and boaters should be cautious when windy weather creates waves on the lake, which can be hazardous for small boats. 

The south-central region of Wisconsin can get warm during the summer months, and for locals, Lake Koshkonong is a popular place to cool off and take a swim in its waters. Lakeland Campground features a designated swimming area, while Pettit's Lakeview Campground offers a large beach and an on-site bar. While swimming is allowed at Lake Koshkonong, the lake is subject to algae blooms, which can prompt health advisories, especially during the summer when the lake water is at its warmest.

Unlike the Quiet Lakes, which offer peace and solitude in the state's remote north, Lake Koshkonong has more energy surrounding it, with several bars and restaurants around the lake offering food, drinks, and, in some cases, entertainment. The 59er Bar & Grill in Milton is known for its authentic Chicago-style hot dogs and Italian sausage, while over in Edgerton, the Anchor offers dining along the lakeshore complete with live music.

If you want to experience more of Wisconsin's lakes, nearby Lake Kegonsa State Park sits on a 3,200-acre lake and offers year-round fishing, trails, and a beach. Alternatively, further north of Lake Koshkonong lies Council Grounds State Park, which features a scenic lake with camping and water activities.
