Recommended Gear for the Fort Collins Area
A 5-weight 9’ moderate fast or fast action rod is a good choice if you’re fly fishing in the Fort Collins area. In terms of fly line, you want floating line for the moving water that you’re going to be fishing. The pockets and pools aren’t overly deep, so you shouldn’t need to get too far down in the water column. Your leader should be able to get you where you need to go.
If you’re fishing in the local reservoirs, a sink tip line is going to be necessary. In the warmer months, these fish are deep in the water column! Your streamers and nymphs aren’t going to be able to get to the necessary depths with floating line.
Have 0x to 4x leaders and 4x to 6x tippet on hand when fly fishing near Fort Collins. You never know when you’re going to want to fish with some exceptionally small nymphs or dry flies!
