Bowman Lake, located in the northwestern corner of Glacier National Park, Montana, is a pristine alpine lake stretching approximately seven miles in length and up to one mile wide. Surrounded by dense forests and towering mountains, this remote lake offers a serene fishing experience away from crowds. Fed entirely by snowmelt, Bowman Lake has exceptionally clear, cold water that remains chilly throughout the summer. While not necessarily known for trophy-sized fish or exceptional fishing productivity, Bowman Lake provides anglers with a unique opportunity to fish in a breathtaking wilderness setting. The lake's remoteness, accessed via a bumpy dirt road from Polebridge, adds to its charm as one of Glacier National Park's hidden gems for those seeking a peaceful fishing adventure.

Under the Montana Stream Access Law, the public may use rivers and streams for recreational purposes up to the ordinary high water marks. Although the law gives recreationists the right to use rivers and streams for water-related recreation, it does not give them the right to enter private lands bordering those streams or to cross private lands to gain access to streams without landowner permission. Montana's stream access law ensures public access to surface waters by public bridge or county road right-of-way. The width of a public bridge or public road right-of-way easement is the same as the public highway to which it is attached.
