Fall Nymphing Tactics

The Days of throwing dry dropper are slowly coming to an end and our Colorado Trout are starting to key in on smaller sub aquatic insects. With the Brown Trout Spawn in full swing Rainbow Trout areyarn egg close behind looking to pick up an easy egg meal. That being said egg patterns are going to be a great lead fly in a two fly nymph rig. A lot of people prefer to use beads and with the lifelike appearance you can certainly understand why. By do not over look traditional yarn eggs. These fly patters are extremely effective and I have found that the yarn tends to get caught in a trout’s teeth allowing you a little more time to set the hook.

My basic fall nymphing set up starts with an egg pattern and is trailed by a Blue Winged Olive nymph/ emerger or midge pattern. I have a lot of faith in Flash Back RS2’s so that will usually be my go to pattern if the trout are getting picky. I like to have about 5 to 6 feet of leader between my indicator and weight for fishing deeper runs and I will adjust my indicator distance accordingly based on water depth. You will find that a lot of fish are holding at the head of a deeper pool in the shallow riffles. These areas are extremely fun to nymph becauseTrout will often strike aggressively as your nymphs travel by. There is no mistaking a strike in shallow riffles, your indicator will jump quickly and many times move with the fish as it try to spit your hook. If your client of fishing buddy says “I think that was bottom” the him that bottom doesn’t move.


Many rivers are low and clear so sight fishing is an option on many Colorado Drainages. Please stay off of the Brown Trout Redds should you seen them and focus your fishing efforts elsewhere. LIke above mentioned Rainbow Trout will often stage behind the Browns looking for eggs.


You will find that a lot of deeper pools are moving very slowly with current water levels. Try lightening up your nymph rig if you are fishing these ares. This will keep you from getting snagged and allow your flies to drift in the upper water column. The fish in these pools have been suspended eating emerging midges so be sure to set on any inconsistent movement from your indicator. Often times strikes in slow water can be very difficult to notice so it is good to get in the habit of setting on any indicator movement.

Now is a great time to find some larger fish trying to put on some extra pounds before winter sets in.
