Ruby is the perfect name for this river, for it is a largely hidden, sparkling gem. Its crystal clear waters begin in the pristine Beaverhead National Forest in southwest Madison County, ... morebetween the Snowcrest Mountains and the Gravelly range. While it starts as a rather thin trickle, it picks up more than a dozen mountain, freestone creeks, and gains velocity as it flows for 40 miles past Alder and into the Ruby Reservoir. Past Alder, the river runs north between the beautiful Tobacco Root Mountains to the northeast and the Ruby Range to the southwest. Nestled in the quaint Ruby Valley, the river is conveniently located a mere thirty minutes from Ennis and a lovely one-hour drive from Bozeman. Like many other rivers in this region, the Ruby is small at only 76 miles in length, but it is full of surprisingly large fish.
Leaving Alder, the Ruby exits the reservoir as a tailwater and supports abundant midge, caddis, and Pale Morning Dun (PMD) hatches. For a short time the river passes through a scenic, arid canyon before abruptly transitioning into a meandering open agricultural valley. At this point the Ruby runs over vast swaths of private land, sometimes making access difficult. The 40 mile descent from Alder to Twin Bridges also crosses over high-end ranch properties, where again, access can be challenging although public access points do exist and can be easily located.
The river is open year round to fishing and conditions are good through all seasons. Springtime on the Ruby brings hatches of baetis and early season caddis. When the water warms in summer, the river will explode with Yellow Sallies and Pale Morning Duns (PMDs), along with hoppers and other terrestrials. Late summer and early fall is considered by many to be the best time to fish, as clouds settle in the high mountain valley providing fast paced action for the streamer enthusiast. Running a nymph rig subsurface, or using a dry/dropper combo is the best technique on the Ruby throughout the year.
Fish will jump for hoppers during the late summer months, while streamer-fishing can very satisfying throughout the summer and early fall. A predominantly brown trout fishery, the Ruby is full of trophies that often reach 18 – 20 inches. The greatest numbers of rainbow trout are found in the first few miles of the river just below the dam. If you seek a unique opportunity, the upper portions of the Ruby rumored to hold rare cutthroat trout and arctic grayling.
