Fly Fish The Ruby River

Here at Montana Fishtales

The Montana River of Your Dreams!

The width of a small street, the picturesque Ruby presents views of mountains in all directions as you cast your fly to cut-banks and into deep, fish-filled, pools. If casting dries to ample 12-17” browns sounds right up your alley, then make sure to include a day on the Ruby.


Along with the incredible fishing, you’ll also enjoy the incredible scenery. A truly beautiful Montana alpine valley view surrounds the upper river.

Originating in the Gravelly Range, the upper Ruby is a freestone river before it settles and forms the Ruby Reservoir. Characterized by short riffle corners, plunge pools and boulder runs, the upper Ruby has more pocket water than downriver.

Here you will find rainbows, cutthroats, and a few nice browns. This is an area that offers a great opportunity for beginners, as it is home to a very healthy population of Arctic grayling which are eager to rise to your dry fly.

Trout Jumping Ruby River Montana

The lower Ruby is a western tailwater. She has prolific and predictable hatches of caddis, mayflies, and stoneflies all providing food for its healthy trout population. Near the dam, you will catch more rainbows than browns on small Beatis and Caddis nymphs, while the lower stretches are home to mostly brown trout.

The lower Ruby looks like a spring creek with lots of overhanging willows and cut banks. Its easily-waded gravel bottom is perfect for the angler casting dry flies upstream to rising browns.

Abundant hatches of PMD’s, Yellow Sallies, and Caddis are common, but the Ruby’s hottest action would be mid to late summer when the river larger browns are really looking for ‘hoppers; explosive strikes make for truly exciting fishing!
