Ruby River Fly Fishing
The Ruby River in Montana is a diverse and productive wild trout fishery, offering a variety of fly-fishing opportunities. On the Upper Ruby, anglers can catch rainbow trout, brown trout, cutthroat trout, cutbows, brook trout, and grayling. This section is known for its dry fly fishing, where anglers primarily use dry-dropper setups and single dry flies. The Upper Ruby is especially productive for numbers, with average fish ranging from 8 to 12 inches, along with the chance to land larger 15- to 20-inch brown trout.
Below the Ruby Dam, the river transitions into a tailwater fishery known as the Lower Ruby. This stretch offers excellent brown trout fishing, along with strong opportunities for rainbow trout and mountain whitefish. Fish on the Lower Ruby tend to be larger, averaging 15 to 18 inches, with consistent chances at 19- to 20-inch trout.
In addition to the main river, several Ruby River tributaries provide classic small-stream, technical fly fishing. These waters challenge anglers with tight casting conditions and reward precise presentations along undercut banks, log structures, and overhanging trees. With the variety of species found throughout the Ruby Valley, anglers can even pursue the “Ruby Grand Slam” by catching all seven species in a single trip.
