Roaring Fork: Emma to Basalt
Roaring Fork: Emma to Basalt — Fishing Report for April 24, 2026
Quick Stats
Flow: 216 CFS | Trend: Stable | Fishability: Good | Weather: Mostly Sunny, High 64°F
The Bite
This is the window. With snowpack sitting at a fraction of normal across the basin and water-year precipitation well below average, the spring runoff pulse is expected to be mild and early — meaning the pre-runoff dry fly season you'd normally fight to hold onto through late April may extend a bit further than usual. But don't get complacent: Sunday's rain and thunderstorms could nudge flows and cloud things up. Fish today and Saturday like they matter.
At 40°F, water temps are on the cooler end of the active range, which means fish will be slower to move early. The morning belongs to Skwalas — these chunky stoneflies have been crawling the rocks and grassy banks on warm afternoons, and with a 64°F high today, midday conditions should bring them out. Work the slower seams along undercut banks and gravel bar edges with a size 8-10 Skwala dry, and don't be surprised by an aggressive eat. The BWO hatch, typically the headliner this month, will be compressed on a mostly sunny day — look for a narrower emergence window between roughly 1 and 3 PM rather than the all-afternoon show you'd get under cloud cover.
If the surface stays quiet, don't force it. The nymph game is reliable right now, and fish are holding in the deeper runs ahead of the seasonal transition. Stonefly nymphs and Baetis patterns fished through the mid-column will find willing browns and rainbows throughout the day.
What to Fish
- Skwala Dry #8-10 — Fish tight to grassy undercut banks and slower seams from late morning through early afternoon. Let it sit and twitch slightly if there's no take on the drift.
- Parachute BWO #18-20 or Sparkle Dun BWO #18-20 — Best between 1 and 3 PM in any shaded or slightly overcast stretch. Focus on tailouts and slower water at the tail of runs.
- Pat's Rubber Legs #10-12 — Anchor nymph for deep runs and pocket water. Fish it heavy and slow along the bottom.
- Pheasant Tail #16-18 — Trail 12–16" behind the Pat's as a Baetis nymph imitation through mid-depth runs.
- RS2 (gray) #20 — Effective in slower, clearer water, especially during or just before the BWO window.
- Dirty Midge #16-18 — Reliable filler pattern in the 10 AM–noon window before the stonefly and BWO action picks up.
Tactics & Rigging
For the nymph setup, rig Pat's Rubber Legs on point with a Pheasant Tail or RS2 trailing 14" above on a tag off the tippet ring. Use 4X fluorocarbon to the anchor and step down to 5X for the dropper. Add enough split shot to tick the bottom through the deeper runs — the fish aren't chasing right now, so get the flies in front of them. Focus on the inside seams of bends, the soft water behind mid-channel boulders, and the transition zones where fast riffle water slows into deeper pools.
For the Skwala dry, fish it solo on 4X fluorocarbon and work the banks methodically. Cast upstream and slightly across, mend once to kill any drag, and let it ride the seam naturally. If you see a fish follow but refuse, try a single twitch — Skwalas are active insects and a little movement can trigger a commitment. During the BWO window, switch to a lighter 5X or 6X leader and present the dry with a reach cast to extend your drag-free drift through the tailouts.
Access & Logistics
Access along this corridor is generally straightforward — the Emma boat launch and Basalt River Park both offer reliable parking and easy wade access. Wading is comfortable at 216 CFS with standard felt or rubber-soled wading boots. Crowds are light for April, and a Friday afternoon shouldn't change that much. Before launching your gear, rinse and dry all equipment thoroughly — the Roaring Fork is a priority waterway for aquatic nuisance species prevention.
Stop by Taylor Creek Fly Shop or Frying Pan Anglers for flies, local intel, and to support the shops that keep these fisheries healthy. Always verify current regulations with CPW before fishing.
Looking Ahead
Saturday looks like a carbon copy of today — take advantage of it. Sunday brings rain and thunderstorms, which could add a touch of color to the water and push flows slightly, but given the light snowpack year, a dramatic spike is unlikely. Watch the gauge: if flows climb above 300 CFS and the water picks up turbidity, shift your approach accordingly.
