Nelson Lake is 2,503 acres of water, 31 miles of shoreline, 16 islands, and a few floating bogs. Its water source comes from two named streams, the Totagatic River and Tagalder Creek, and at least four other specific drainage streams. The total watershed drainage area and lake cover about 34,800 acres (approximately 54 square miles) with 16,300 acres being in Bayfield County, Town of

Barnes, and 18,500 being in Sawyer County, Town of Lenroot.

There are four public boat landings, one below the dam and 13 landings at resorts and campgrounds, plus a County Park located next to the dam with picnic tables, grills and restrooms.
