Top 5 Colorado Rivers Fishing This Week
Each river featured below has optimal flows, good water quality, and active hatches. 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
Central Mountains Colorado
The Arkansas River was flowing on the report date at 105 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 42-60°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: February brings prime midge fishing to the Pueblo Tailwater. Look for heavy midge activity from 10am through early afternoon, with fish keying on emerging pupae in the slower runs and tailouts. Blue-winged olives make sporadic appearances on overcast afternoons—when you see risers, switch to a small BWO emerger (#20-22) trailing behind your midge. The cold, nutrient-rich dam releases keep insect populations thriving year-round, making this one of Colorado’s most consistent winter fisheries.
Fishing approach: Study deeper runs and tailouts from a confirmed legal fishing position. Adjust depth and weight to the drift you can reach without an uncertain crossing.
2. Blue River – Below Dillon Dam
Central Mountains Colorado
The Blue River was flowing on the report date at 135 cfs (normal) with a rising trend. Flows were rated fishable on the report date. Water Temperature: 37°F (cold). The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 25-43°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: The Blue below Dillon is experiencing excellent midge activity with consistent hatches throughout the midday hours. At current flows of 135 cfs, fish are holding in predictable lies and actively feeding on midge pupae and larvae. Expect the best surface activity between 11am and 2pm when water temperatures peak. Small baetis (#20-22) may appear on cloudy days—watch for subtle rises in the slower water along the banks.
Fishing approach: Look for reachable seams beside slower water. A controlled nymph drift can cover the holding lane without moving farther into the current.
3. Gunnison River – Black Canyon Gorge
Southwest Colorado
The Gunnison River was flowing on the report date at 383 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 29-47°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: The Black Canyon section is seeing solid midge and small mayfly activity in the accessible tailwater portions. February conditions favor subsurface patterns, with fish responding well to midge clusters and small pheasant tails drifted deep. The nutrient-rich flows from the Aspinall Unit keep insect populations healthy even in the coldest months. Expect the best feeding windows during the warmest part of the day.
Fishing approach: Watch the pool edges before casting. Use a longer presentation when moving closer would disturb fish or require an uncertain route.
4. South Platte River – Deckers
Front Range Colorado
The South Platte River was flowing on the report date at 167 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 39-57°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: Deckers is fishing well with classic February patterns—midges dominate the menu. The reliable tailwater flows create ideal conditions for year-round insect activity. Expect heavy midge emergence from late morning through early afternoon, with fish feeding subsurface on pupae before switching to emergers and adults. The occasional baetis hatch adds variety on warmer afternoons. Small patterns (#20-24) are essential.
Fishing approach: Fish current breaks and shaded structure from an authorized position. Match the fly and presentation to the activity you observe.
5. Taylor River – Catch and Release Section
Central Mountains Colorado
The Taylor River was flowing on the report date at 81 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 15-33°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: The Taylor’s catch-and-release section is experiencing excellent midge activity with fish feeding actively throughout the day. February brings consistent hatches in the 11am-3pm window when dam releases stabilize temperatures. Small baetis patterns become increasingly important as the month progresses. The tailwater’s productivity ensures reliable insect populations even in harsh winter conditions. Match the hatch with small patterns (#20-24) and fine tippet.
Fishing approach: Give a promising seam several controlled drifts, then change depth or pattern. Moving farther along the bank requires a separately confirmed route.
