The Colorado River Between the towns of Kremmling, CO and Parshall, CO offers several public fishing accesses along U.S. Route 40.  The river gradient is fairly mellow through out this section, and offers slow runs, gentle riffles, and deeper holes.   This water is excellent for both nymph, and dry fly fishing.  If you don’t see risers, then fish nymphs. Since this water is a little slower, and shallow in spots, a heavy rig is not usually needed.

guide tip of the week:


The Colorado River is currently at a great flow to fish, and clarity has been just how we like it with about 3-4 feet of visibility.  Water temps are warming up and we are seeing more hatches including golden stone flies, caddis, PMDS, Yellow Sallies, drakes, a few Blue Wings, and midges. Dry Flies, nymph rigs, and streamer fishing are all viable options at the moment. Fish will be feeding in all the common places; rock gardens, riffles, and deep pools. 


Recent Media: 

We love seeing and hearing about your outings as well. Send any fishing photos or stories  you want to share over to and we'll throw 'em up in the reports.


Our guide Tim Joyce is at it again...this time he takes a day off from fishing, and goes fishing instead.   Here are a few nice trout he picked up on Upper Colorado above Parshall, while nymphing with stonefly imitations. Did we mention Tim runs a world class elk hunting guide service as well?


You can get an idea of the water color/clarity in the background as well.


recent history:


late may/early June

Our guide Tim Joyce seems to be getting his clients into some nice trout on the "Upper C"...



A few Salmonflies gave been sighted on the wing in this area...


Early May...

Check out THE REPORT BELOW,  from a recent trip to Byer's Caynon with our Guide John Spriggs.  Also if you enjoy skiing it is well worth watching John's documentary The Book of Pow, which is one of the best, strictly Colorado filmed powder skiing documentaries ever made.  Keep in mind CO has one of the most avalanche prevelant snow packs around, and these guys have the knowledge to ski these crazy lines in it.


Byers Canyon is a short gorge on the upper Colorado River in Grand County, Colorado. The canyon is approximately 4 miles long and is located in the headwaters region of Colorado between Hot Sulphur Springs and Kremmling. This is a beautiful little canyon, full of Brown trout, some big ones too! The wading and walking in the canyon can be very difficult as the banks are lined with big boulders, and you have to hike a couple hundred feet down to the river from the road, access is easier at the mouth of the canyon.

Flys: Pat’s rubber legs 12-8, olive and brindle, Foam wing RS2 size 18, Beatis, and midge patterns

Fished a little slow, water seemed worse for clarity in the canyon compared to the mouth of the canyon and below. Fish seemed to want stoneflies and rs2s.

River Conditions

CFS: 650cfs

Weather Conditions: Sunny and to overcast, 60

Water Clarity: off color 1.5 feet

Water Temp: 45

Trout Holding: Fish were holding tight against the banks, and in the back eddys, along the foam lines.


Guide tip of the Day

Work the slower water against the banks, and eddys, if you find a fish holding in the back eddies or slower water, you will usually find more there, so keep fishing it and adjust depth for deeper pockets! !

Byer's Caynon, this is one cool place.  It is steep, narrow, and tough to navigate, but well worth it. Photos by guide John Spriggs


Uniquely colored browns in this caynon, also take note of the water clarity ( 5/6/2020)


Brown Trout taken on an olive/brown size 8 Pat's Rubber Leg's, and a size 18 grey Sparkle Wing RS2.




Bug Life tatted on my chest:  Byers Caynon usualy has a prolific Yellow sally ( pictured below)  hatch just following the Salmon Fly Hatch.

Baetis (pictured above), Caddis, and other bugs are abundant as well.
