South Fork Report – 9/28/17
Flow: 4400 cfs (Irwin)
Fishing has been great on the South Fork! With the cooler temperatures, action is picking up. Blue Wing Olives, Mahogany’s, and PMD’s have provided great action in the riffles. We recommend trying CDC Biot BWO #16, Brook’s Sprout Baetis #16 or #18, Mahogany Para Extended Body #16, or Pink Biot Hackle Stackers #16. When the sun is out, smaller terrestrials are still working well. Our favorites right now have been pink or purple “Micro” Chubby Chernobyls with a beadhead dropper. Streamer action has been great as well with this cloud cover we have been experiencing over the last few days. White or Olive Peanut Envy’s, Golden Delicious, Sparkle Minnows, and Kreelex Minnows have been our pick. Come by the shop and we can point you in the right direction!
Flow: 600 cfs (Island Park Reservoir)
The Ranch is fishing well with daily hatches of Mahoganies and BWO’s. With our next round of storms coming this week, there should be plenty of cloud cover. We recommend “The Fork” baetis #16, CDC Biot comparadun #16/18, Extended body mahogany dun #16.
The Box is also fishing very well. Again, baetis patterns will produce if you are looking to catch them on top. Nymphing remains the most consistent option. Fish a #8 rubberlegs followed by a midge or pheasant tail pattern in a #16/18. Streamer fishing has also picked up, this is one place on the river where smaller streamers seem to produce better than the larger articulated patterns (not saying they don’t work at all). Darker colors on those cloudy days but always make sure to give white a try at some point.
Below Ashton has seen a ton of improvement as water temps have decreased and the aquatic vegetation has started to break up. Again, baetis and mahoganies have been the top producer. When nymphing, it is hard to beat a zebra midge or brassie this time of year. We recommend a #14/16 zebra midge in black or olive, beadless brassies in red or brass, or tungsten split case bwo’s #18
It has been a BIG FISH fall so far. With temps looking to continue their downward trend, fishing will continue to improve. For now, focus your efforts near creek mouths. As vegetation breaks up in other shallow areas, watch for feeding fish to move in. Leech patterns in fall colors will do the trick. Try adding a trailer fly about 2 feet behind your leech. We like to use a mighty mouse or large scud pattern.
Fishing should be great for the foreseeable future so now is the time to get out!
South Fork Report 7/18/17
Flow at Irwin – 13,500 cfs
It appears we are through runoff for the season and the river is shaping up nicely! If you haven’t been out, now is the time. Nymphing has provided the best action over the last few weeks but expect that to change quickly as the clarity improves and flows continue to drop. Rubberlegs in a size 4 or 6 followed by larger beadheads or san juan worms have been doing really well. Fish will begin moving to the gravel bars and cut banks looking for hatches of pmd’s and easy meals as terrestrial activity picks up. PMD sparkle duns, PMD pullovers, and PMD no hackles are our favorites. Chubby Chernobyl’s, Yellow Sallies, and hopper patterns fished on the bank is another great option. Swing by the shop and we can point you in the right direction! Most of all, have fun and BE SAFE!
South Fork Report – 3/13/17
In preparation for warmer temps and runoff, flows out of Palisades have increased to just over 7,000 cfs. Fishing has been great in spite of the higher flows and many float opportunities have opened up! With the influx of cold water and high cfs, focus on areas where fish will use the least amount of energy. Deep runs, overcut banks, eddies, soft edges near riffles will likely be where you find them. BWO emergence is right around the corner with a few already being seen on a warmer afternoon. Nymphing remains the most productive method. Fish deep with a rubberlegs followed by a pheasant tail or other mayfly nymph in a #14 or #16. San Juan worms are also great when high water is present. Streamer fishing is a great way to entice that larger fish into showing himself. Fish them deep and slow and change up the color until you find what is working. This next week is forecast to bring possible 60 degree temps so now is the time! Come by the shop and we can point you in the right direction.
