Review & Frequenly Asked Questions:

Lake Onalaska is a 4-mile-wide reservoir set on the Black and Mississippi Rivers between Wisconsin and Minnesota. Located in La Crosse County, the lake spans 7,688 acres, is 43 feet deep at its deepest, and is a popular destination for outdoor activities and recreation such as swimming, boating, fishing, windsurfing, and waterskiing in the summer. The lake’s shorelines are home to a myriad of waterfowl and migrating bird species, which makes for a birdwatching haven, and is well stocked with an abundance of fishing, such as bluegill, crappie, northern pike, small and largemouth bass, and walleye. During the fall, the bluffs surrounding Lake Onalaska and the Mississippi River explode into rich tones of reds and golds, drawing tourists from across the country, while the winter months offer excellent ice fishing and ice sailing.
