One of the most popular winter activities in the watershed is snowmobiling. All of these are tied into the Department of Conservation's Interconnected Trail System. Most maintain dozens of miles of trails. While most clubs do not object to cross-country skiers or hikers using snowmobile trails, they note that landowners may feel differently because hikers and skiers are not covered by the Maine Snowmobile Association's liability insurance. If sued by a cross-country skier, landowners are nonetheless protected in large measure by the Landowner Liability Law.
Some clubs have agreements with landowners to allow hikers and skiers.
In general, ATV use on snowmobile trails is strongly discouraged or prohibited. Hiking trails open to the public are limited to the handful of private nature preserves in the lower watershed. Given the potential to obtain agreements with private landowners to use the large network of snowmobile trails that criss-cross the watershed, most towns have not identified hiking access as a problem.
