San Miguel River: Norwood to Naturita

San Miguel River: Norwood to Naturita — Fishing Report for April 24, 2026

Quick Stats

Flow: 79 CFS | Trend: Stable | Fishability: Good | Weather: Mostly Sunny, High 69°F

The Bite

April on the lower San Miguel is one of southwest Colorado's best-kept secrets, and right now the river is in a genuine sweet spot. At 79 CFS — steady against its 10-day average — the channel is carrying enough water to push fish into productive holding lies without the off-color turbidity that comes with high-country melt. With basin snowpack sitting at just 10% of normal this year, that melt-driven runoff pulse is going to be modest and likely earlier than usual, which means this fishable window could stretch well into May. Enjoy it.

Today's mostly sunny skies and a high of 69°F are a mixed bag for the afternoon Baetis hatch. BWOs prefer cloud cover, and a bluebird day can suppress the emergence or push it later and shorter. That said, the hatch should still materialize — watch for risers in the slower valley pools and tailouts between 1 and 4 PM, especially if any clouds build. Morning hours are the more reliable play today: midges will be active from 9 AM through midday, and nymphing the deeper bends and undercut banks with Baetis patterns should produce steady action before the afternoon surface show. Water temps aren't available from the gauge today, but at this elevation and with these air temps, expect the river to be in the low-to-mid 40s°F — fish will be active but deliberate.

The weekend forecast adds a wrinkle worth noting. Saturday looks similar to today, but Saturday night into Sunday brings showers and thunderstorms. A rain event can trigger excellent BWO activity — if you can get on the water Sunday morning before flows respond, the overcast and moisture could set up one of the better hatch windows of the spring.

What to Fish

• Sparkle Dun (olive) #18-20 — Best dry fly choice for the afternoon hatch; the trailing shuck triggers hesitant risers. Dead-drift drag-free through the seams where you see surface activity.
• Parachute BWO #18-20 — High-visibility option when you need to track the fly in choppy water or low light. Fish it the same way — natural presentation is everything.
• CDC BWO Emerger #20 — Try this in the film when fish are sipping subtly and ignoring standard duns. Trail it 12–18" behind a Parachute Adams as a dry-dropper if you want a searching rig.
• Pheasant Tail Nymph #18-20 — Morning workhorse. Dead-drift through the deeper pools and along the far bank where undercuts hold fish.
• Griffith's Gnat #18-20 — Midge cluster pattern for the 9 AM–noon window. Effective in the slower, siltier pools.
• Elk Hair Caddis (tan) #16 — Worth having on late afternoon; the first caddis of the season are beginning to show sporadically.

Tactics & Rigging

For morning nymphing, rig a Pheasant Tail on point with a small Griffith's Gnat or midge pupa 12–16" above it as your dropper — the PT anchors the setup and the midge rides higher in the water column. Use 5X fluorocarbon to the point fly and 6X to the dropper. Focus on the deeper outside bends and any undercut bank structure; the low gradient here means fish stack in the slower, deeper water rather than the riffles.

When the afternoon hatch comes on, switch to a single dry on 6X fluorocarbon and slow down. These valley pools are wide and clear enough that a heavy tippet or sloppy cast will put fish down. Approach risers from downstream, keep your profile low, and let the fly ride the current without drag — even a subtle wake will kill the take. If you spot fish sipping in the film without committing to duns, drop to a CDC emerger on 6X or 7X and present it flush in the surface.

Access & Logistics

BLM land along the Highway 141 corridor provides public access at multiple points between Norwood and Naturita — look for BLM access signs along the road. The broader valley character makes wading straightforward, and the light pressure means you're unlikely to share water with anyone. Verify current regulations and bag limits with CPW before fishing. Stop by local fly shops in the Montrose or Telluride area for flies and current intel — and to support the shops that keep these fisheries on the map.

Looking Ahead

Sunday's rain and cloud cover could set up one of the better BWO windows of the spring — if you can only pick one day this weekend, Sunday morning before any runoff response is worth the drive. With snowpack at historic lows basin-wide, the main runoff pulse should be mild and short-lived, giving this section an extended fishable window well into May.
