River Description

WOW!! This is it!! The "Mad Mile" !! Home of the Bigfork Whitewater festival held at the end of May.

Locals get to run this as early as the first part of April, depending on snow melt. Runnout extends longer than most Montana Rivers, thanks to Swan Lake, which feeds out warm water into July most years.

If you are new to the mile, be sure to scout the "Big Drop" about a hundred yards from the putin.
