Flows and Water Clarity
The Roaring Fork is running low and clear. Flows are approximately 65 cfs below Maroon Creek (gauge is ice affected) and 178 cfs at Emma. Water temperature remains in the mid thirties.
This past week brought us sunshine, snow and a wide range of temperatures. As a result, we’ve been seeing river conditions change throughout the week, but we’ve been catching fish throughout it all! Nymphing continued to be productive during the colder streaks, and we were really excited to see some fish rising during the warmer days. Dust off those dry fly boxes, because we’re starting to catch fish on the surface!
Fish haven’t been seriously looking up for a while, so fish were eating dries readily when we found the right pockets. Small griffiths gnats, midge clusters, cripples and Parachute Adams were all productive, and we expect to see dry fly action to increase throughout the spring pre-runoff. When fishing midge and BWO dries, make sure you’re being stealthy, downsizing tippet and fly size, and using longer leaders. It can be tricky to dial in the right set up, but when you do it’s a whale of a time!
As mentioned previously, fluctuating temperatures required us to change our tactics while on the river this week. On warmer days, we saw the water getting slightly off color when ambient temperature reached the upper forties, but has since returned to being very clear with the snow and cold weather. With a mixed forecast for the coming week, make sure you’re headed to the river with a few different set ups.
Tomorrow and Sunday should be beautiful on the river, so bring a dry fly set up and keep an eye out for rising fish. Focus your efforts on mid day when dry fly fishing. Nymphing is still the ticket early and late in the day, as well as on the colder days next week. We’ve been seeing a large number of small winter stoneflies (click here to watch one crawl around Jarrod’s hand), so leading with small stonefly patterns and trailing midges and baetis is still your best bet.
We continue to be on the lookout for spawning activity, if you see anything please, let us know as we want to make sure we’re helping local anglers stay off of redds. Read more below.
The Spring Spawn
Spring isn’t in full swing yet, but it’s time to start thinking about the Rainbow Trout Spawn. We know that for the most part the fly fishing community is educated and thoughtful about responsible use of the resource and protecting future generations of fish, but we think that it is still worth reminding everyone to be mindful of spawning fish as we move into spring.
Trout create spawning beds or “Redds,” which are generally found in shallow, moving water. Identifying these redds is an important skill as an angler and helps us fish ethically. Redds are generally composed of smaller rocks and gravel that are lighter in color than the rest of the river bottom due to spawning fish brushing the rocks as they mate and clearing them of algae and other organic material. These beds provide safety for the eggs and alveins (fry) that are a result of the spawn and the next generation of fish!
Stay away from redds, fish deeper water where trout are actively feeding, and use good fish handling practices. If you are hitting the water with someone who is new to the sport, please use this time of year as an opportunity to share how to fish ethically and be a steward of the resource.

Common Hatches and Food Sources
Midges, Baetis, and Stoneflies.
Midge Larvae and Baetis nymphs are the standard sources of food present in the upper fork during the winter and late spring, but as the weather warms we are seeing larger patterns produce well. Try the Element Flies Pat’s Stone Runt (size 16, black) or a Two Bit Hooker (size 16, black).
We’re still seeing some fish rise intermittently to eat hatching midges, so make sure you have some size 18-22 midge imitations in your box!
We haven’t really been seeing them yet, but the caddis should start moving around soon. We’re having some success on generalist patterns (like size 16 Hare’s Ear) that imitate caddis well, so fish might be starting to key in on caddis larva.

We haven’t been throwing streamers much yet, but it might be worth a shot! This is traditionally a great time to start messing around with your streamer set up. If you whack some fish on streamers, let us know! (or don’t… we understand)
Nymphing is the most productive technique during this time of year. Finding deep holding water and using weight to get your flies down will be crucial to success. Longer leaders and heavy split shot will help you get your flies in front of more fish. Leading with larger jig style or tungsten patterns has been a very productive technique for helping smaller flies get down deeper.
Small midges and baetis are the staples when fishing this time of year, but don’t be afraid to try something out of the ordinary. Small stoneflies are working surprisingly well right now! If you’re not finding success, get creative with your point flies– larger bugs have been producing occasionally too!
Dry fly hatches are beginning to increase in frequency, so keep an eye out for pods of rising fish. Spring dry fly hatches can be sporadic compared to the summer months, but are incredibly fun and rewarding to fish. Midges are the predominant hatch right now, so switching to small dry flies and fine tippet is your best chance at fooling fish.
As we move into spring, streamers will become important in your rotation! Small streamers tend to be best during early spring, and be sure to focus your efforts on deep pools and structure.
Information About The Roaring Fork
The Roaring Fork River is a freestone river that runs 70 miles from Independence Pass through Aspen, Basalt, and Carbondale until it reaches its confluence with the Colorado River in Glenwood Springs. The cold, clean waters of this famous river support an incredible array of aquatic life including brown, rainbow and cutthroat trout. The Roaring Fork is designated as a “Gold Medal” fishery, meaning it offers some of the best trout fishing in the nation to beginners and seasoned anglers alike.
