Use caution
Colorado River is a cautious call right now.
Current USGS flow is 841 cfs and has been stable for about 6 hours. Today's flow is below the normal seasonal range, which begins near 896 cfs. This is below normal, so edge depth, temperature, and pressure matter.

Best supported approachWade
Compare wading, bank fishing, and floating before choosing how you will fish.
Bank / edge62/100
Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.
Float62/100
A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

How to fish it
This is the upper Colorado River plan.
The upper Colorado around Parshall and Kremmling is a major trout corridor, but it is too broad for generic advice. Start with the Parshall and Kremmling gauges, then match your plan to wade access, boat traffic, water temperature, and CPW rules.
- Use RiverReports near Parshall and USGS 09058000 for upper-river flow context.
- Plan around hatches, runoff, late-summer temperatures, and seasonal closures.
- Respect private land; public access is not continuous along the river.
- Use the middle or lower Colorado pages for State Bridge, Catamount, Glenwood, or downstream planning.
Why the score looks this way
FlowUse caution
USGS shows 841 cfs with a stable over about 6 hours trend. Today's flow is below the normal seasonal range, which begins near 896 cfs. This is below normal, so edge depth, temperature, and pressure matter.
Water temperatureUse caution
USGS water temperature is about 69F. Fish early and stop if handling stress is likely.
Best mode nowUse caution
Wade: Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.
SeasonHelps score
Summer: Caddis, PMDs, stones, and terrestrials can be strong when water temperatures stay safe.
Public alertsHelps score
No active NWS alert was returned for this forecast point.
Read the water
What changes the plan.
The upper Colorado fishes best when flows are stable, water temperatures are trout-safe, and clarity is good. During runoff, heat, or seasonal closure windows, use official sources before deciding to fish.
Low and clear
Use longer leaders, smaller flies, and careful wading around visible fish.
Stable medium flow
A flexible nymph, dry-dropper, streamer, and hatch-matching window.
High runoff
Focus on safe banks and inside edges only if clarity allows; avoid hard crossings.
Warm late summer
Check temperature, fish early if safe, and stop targeting trout when handling stress is likely.
Your trip plan
Know when to go—and when to skip it.
Best flows
Use the RiverReports Parshall chart and USGS Kremmling station together. Stable or slowly falling flows are the easiest trout-fishing window; high runoff should narrow the plan to safe edges or a boat day, while low warm water should make temperature checks the first decision.
When to skip
Skip the upper Colorado when runoff makes crossings unsafe, when late-day temperatures are stressful, when seasonal closure details are not clear for the exact reach, or when your chosen public access would force trespass or crowding.
Local plan
Choose the reach before choosing flies: Parshall and Williams Fork context for upper access decisions, Kremmling for the main gauge read, and Radium only when you are intentionally shifting toward the middle-river style of water.
Backup water
If the upper Colorado is high, warm, crowded, or restricted, compare the Blue River for a technical tailwater-style day, the Williams Fork for a tributary option, or the Big Laramie River for a smaller headwaters plan after checking current rules.

TimingWhat to watchUseful flies
WinterMidges, small baetisZebra midge, RS2, black beauty, small pheasant tail
Fly pattern · report suggests “Zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it ↗
Fly pattern · report suggests “RS2”RS2Start with the beadless architecture: two dark-dun Microfibett tails separated behind a slim, tightly twisted and visibly segmented dubbed abdomen; a fuller thorax; and saddle-hackle web clipped into a short angled wing bud. Rim Chung's original-style form uses natural beaver dubbing and hackle web. CDC- or Antron-wing ties, beads, curved hooks, flash, and tailless Avatar-style flies must remain labeled variations.See photos & how to fish it ↗+ 2 more reviewed guides in the Fly Box SpringBWOs, caddis, stonesBWO emerger, caddis pupa, stonefly nymph, hare's ear

Choose a named reach before deciding which gauge applies.
02
Fish banks and soft inside seams during higher flows.
03
Use nymph rigs in riffles before switching to dries during hatch activity.
04
Respect private land and avoid assuming road-visible water is public.
05
Carry a thermometer in late summer.

Common questions
Before you leave.
What reach does this Colorado River page cover?+
It covers the upper Colorado around Parshall, Williams Fork, and Kremmling. Use the middle and lower pages for downstream reaches.
What flow source should I use?+
Use the RiverReports Parshall/Williams Fork chart and USGS 09058000 near Kremmling for upper-river context.
Is the upper Colorado good for dry flies?+
Yes when hatches or terrestrial windows are active, but nymphs and streamers are often more reliable outside those windows.
When should I avoid fishing?+
Avoid unsafe runoff, warm water, seasonal closure conflicts, and muddy storm pulses.
