Yellowstone Lake is a 453-acre impoundment in southwestern Wisconsin's Lafayette County, with a maximum depth of 14 feet. The lake offers multiple access points, including a public boat landing and beach area. The DNR manages a no-wake zone that's particularly suitable for canoe and kayak use.

The lake features boat rentals available daily from 8 AM to 8 PM during the summer season through Labor Day, offering canoes, kayaks, and pontoon boats. A concession area (the Dairy Store) operates Thursday through Sunday from 11 AM to 7 PM, providing food and basic supplies.

Wildlife viewing opportunities are abundant, with over 170 bird species documented in the park. The northwest end includes a designated Waterfowl Area with marshy habitat. The park maintains 31 bat houses around the lake, which help control the mosquito population during summer months.

The lake's water clarity is very low. Fish species include musky, panfish, largemouth bass, northern pike, trout, and walleye. The lake is regularly stocked with game fish, though a fishing license and trout stamp are required for anglers.

The surrounding Yellowstone Lake State Park encompasses 1,000 acres with multiple hiking trails offering views of the lake. A dam at the southeast end controls the lake's water level, where the Yellowstone River exits. The lake was artificially created approximately 75 years ago and has developed into a significant recreational resource for southwestern Wisconsin.

For paddlers planning overnight trips, the park offers camping facilities, including a large family campground near the beach and boat landing areas. The park maintains regular hours from 6 AM to 11 PM year-round, and a vehicle admission sticker is required for entry.
