Nowitna River Professional Review and Guide
"Rising in the Kuskokwim Mountains, the Nowitna River flows northward for nearly 300 miles and enters the Yukon River about 45 miles northeast of Ruby. A medium-size, meandering, nonglacial stream, the Nowitna traverses a remote, primitive area. Flowing swiftly, with occasional whitewater, the river travels through rolling hills, canyons, broad valleys, and flats on its northward journey.
Black and white spruce, hardwoods, and shrubs characterize the vegetation throughout the river corridor. From headwaters to mouth, the river drops from 1,000 feet above sea level to 150 feet and is generally wide and deep. Known locally as the Novi, the river follows a rather serpentine course, except for the section from Mastodon Creek to 10 miles below the confluence with Big Mud River, in which the river straightens and picks up speed."
