Good morning, anglers! The Colorado River is shaping up for an exciting day on the water with spring hatches and improving conditions. The sun will rise at 6:30 AM and set at 7:45 PM today, giving you plenty of daylight to cast your lines. Weather-wise, expect mild temperatures ranging from 55°F to 63°F, light morning winds, and the possibility of gusts in the afternoon.
The river flows are stable between 850 and 950 cubic feet per second (CFS) near Kremmling, with water temperatures lingering around 42°F to 46°F. The clarity is mostly clear but may turn slightly tinted as the day warms up, especially downstream of State Bridge. With snowmelt on the horizon, now is prime time to fish before runoff complicates things.
Fish activity today is centered on spring hatches, particularly Blue Winged Olives (BWOs), midges, and early stoneflies. Late morning to mid-afternoon will be the most productive window for catching trout. Recent catches have included healthy populations of rainbow trout and brown trout, with some anglers reporting large specimens near transitional zones and deeper runs.
For techniques, nymphing is highly reliable. Try a double-nymph rig with a Pat's Rubber Legs or Tazmanian Devil as your attractor, paired with a trailing RS2 or Zebra Midge. For those who enjoy fishing dries, keep an eye out for BWOs emerging mid-morning on overcast afternoons—dries like a Blue Wing Olive Parachute (#18-22) work wonders. If streamer fishing is your game, opt for an Olive Slump Buster or Mini Dungeon, focusing on low-light hours or cloudy conditions with slow, deep retrieves.
Two hotspots today are worth the trip:
1. **Upper Colorado between Kremmling and Parshall**: This stretch offers a mix of riffles, deep runs, and soft seams where trout are actively feeding. The diverse water types are perfect for anglers looking to switch between techniques.
2. **Lower Colorado from State Bridge to Dotsero**: Slightly warmer conditions here have ramped up both the nymph and streamer bite. Be mindful of muddying water later in the day as snowmelt picks up.
As a reminder, rainbow trout are starting to spawn in some areas, so please avoid fishing in active spawning zones and follow local regulations to keep our waters sustainable for all. Keep your catch wet if photographing and have a fantastic day enjoying the beauty and bounty of the Colorado River! Tight lines!
