Top 5 Colorado Rivers Fishing This Week
Each river featured below has optimal flows, good water quality, and seasonal insect activity. These best Colorado rivers provide diverse fishing opportunities with current Colorado river conditions that favor active feeding. Whether you’re targeting tailwaters or freestone streams, the top 5 Colorado rivers this week provide exceptional fishing.

1. Arkansas River – Pueblo Tailwater
Front Range Colorado
The Arkansas River is currently flowing at 97 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 38-56°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: Dam releases create stable tailwater conditions ideal for winter fishing. Midges and small nymphs remain active throughout the season, with streamer patterns effective in deeper runs.
Where to Fish: Higher tailwater flows create more holding water. Target deeper runs, tailouts, and slower side channels where fish can hold out of the main current.
Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.
Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.
Regulations: Artificial flies & lures only
