WITH more than 70,000 miles of streams and thousands of ponds and lakes, swimming and boating in the national forests take a prominent place in the recreation picture. For those who would explore by canoe, the Superior National Forest in Minnesota offers outstanding opportunities. Sailboats, speed-boats, and excursion craft also ply some of the national-forest waters.
As to swimming, the visitor has a wide range of choice—from the warm waters of Florida to the icy water of alpine lakes or streams. In many places the Forest Service has facilitated aquatics through beach improvement, lifeguard service, installation of diving boards and rafts, damming streams to raise water levels, bottom grading to remove sharp rocks, and construction of dressing rooms and showers.
