Lake Kampeska is a 5,250-acre glacial lake located near Watertown in northeastern South Dakota. With over 13 miles of shoreline, it offers ample opportunities for paddling and exploration. The lake features five public boat launch ramps distributed around its perimeter, providing convenient access points for paddlers.

Known for its excellent fishing, Lake Kampeska supports populations of walleye, smallmouth bass, yellow perch, and various panfish species. Wildlife enthusiasts may spot white-tailed deer along the shoreline and diverse birdlife including great blue herons, ospreys, and bald eagles.

The lake's water quality is closely monitored, with improvements made since the 1990s to address previous issues with fertilizer runoff and sedimentation. A weir on the inlet-outlet channel helps control sediment inflow from the connected Big Sioux River.

Paddlers should be aware of potential motorboat traffic, as boats of all sizes are permitted on Lake Kampeska. A no-wake zone exists in Hidden Valley on the lake's east side. The Kampeska Yacht Club hosts an annual sailboat regatta, adding to the lake's recreational offerings.

Amenities around Lake Kampeska include Sandy Shore State Recreation Area, Memorial Park, and city parks offering camping, picnicking, and swimming opportunities. A 15-mile bike trail parallels the lakeshore, providing additional recreational options.

Spring and early summer are ideal for smallmouth bass fishing in shallower areas, while walleye tend to move to deeper waters during summer months. The lake is also popular for ice fishing in winter, particularly for yellow perch.

Lake Kampeska holds historical significance as an early settlement site predating South Dakota's statehood. Its picturesque setting has inspired numerous wildlife artists, most notably Terry Redlin, whose depictions of the lake are displayed at the nearby Redlin Art Center in Watertown.
