The area is over-shadowed because of the more famous waters available nearby such as Montana's Madison, Yellowstone, Firehole and Galletin rivers, Idaho's Henry's Fork; plus the numerous "grapevine", hush-hush-toned venues in western Montana & north-west Wyoming.
Suffice it to say that I will return to the area next fall. In addition to drifting the Big Hole and both wade-fish and float the Beaverhead, I will also explore Pointdexture Slough, a spring creek that flows into the Beaverhead about 3 miles out of town. This time I'll visit during the third week of September because we did experience some nasty weather for two days. At times the early snows and high winds made it difficult to fish...let alone cast.
I can't say enough about the class-act of Tom & Mary Smith's Back Country Anglers; #1 guide Andy and Tom's mellow canine partner, Tippet. All were great hosts; at the lodge, the shop and while on the water. Their personal service and friendly "down-home" demeanor was appreciated by both my bro-in-law Jim Williams and myself. I highly recommend them if you visit the Dillon area.
We floated the Big Hole river twice and the Beaverhead once. The best dry fly fishing occurred during snow flurries on the Beaverhead. We cast to rising trout for over three hours and landed 10-12 rainbows & browns to 18". The trout were in pods, elevated in the upper water column and feeding voraciously and steadily on #22-24 emerging Psuedocleons. We even hooked a couple on our indicator-dry; a #14 Parachute Black Ant.
The Big Hole had no rising fish so we indicator-fished using a San Juan Worms trailing either a #16 Copper John or #18 Micro-May. Most trout...and whitefish...were duped on the smaller patterns.
