The Fall River is a crystal clear spring creek tributary of the Deschutes River lined with Lodgepole pine and lush green meadows. This barbless, fly fishing only river is an important contributor of high quality water to the Deschutes. As with all spring creeks, the Fall River's flows are clear, cold, and steady as it flows to join the Deschutes between the towns of Sunriver and LaPine. The river varies in depth and structure but is a smaller, intimate river. Downed timber that crisscross the river and undercut banks provide habitat for the river's trout while weedbeds dot the white pumice bottom and provide habitat for the river's insect population. The brook and brown trout average between 8 and 10 inches, with rainbows regularly in the 12 inch range. Occasionally a holdover rainbow approaches and sometimes exceeds 20 inches with whitefish typically ranging 6 to 12 inches.
The most popular access points, include: Fall River Hatchery, Fall River Campground (the river's only campground), and Forest Route 4360 to a river-crossing called "the tubes". At "the tubes", the river passes under the road through culverts with parking areas on each side. A well-worn trail help you trek up or downstream.
Large fish continue to be the norm out here. Euro nymphing or light weight wool strike indicators are both ideal for this type of water. There has been little dry fly activity and the hatches that are occurring are mostly being ignored by the fish. Baetis nymphs, midges, and eggs in a size 18 or smaller have been consistently productive. Small white Wooly Buggers and sculpins are getting fish as well.
