It's been a really solid week on the Yampa. Flows at the Steamboat gauge are sitting right around 350 CFS — low enough to read the water well, high enough that the fish are comfortable and spread out. We've been finding browns and rainbows stacked in the transitional water, where the faster riffles slow into the deeper runs. Had a great day Tuesday with a first-time fly fisher who landed a 19-inch brown on his third drift — that one definitely got a howl out of me. BWOs have been coming off nicely on the overcast afternoons, and we've had some genuine dry fly action in the slower seams. Mornings are still a bit cold, so we've been starting on nymphs and switching to dries once things warm up around 11. The Elk River is also fishing well right now if you want a change of scenery — clarity is excellent and it's an easy wade.
Early April conditions: The Yampa Valley is in spring transition. Flows are rising from snowmelt as temperatures warm. Water clarity remains good in most sections. Blue-Winged Olives are the star of the show on cloudy afternoons; midges remain reliable all day. Expect fishing to improve through April as water temps climb toward 48–54°F. The stretch from Stagecoach Dam through downtown Steamboat Springs is currently CLOSED — check CPW for current status before heading out.
Hatch charts, fly picks, and conditions notes below are refreshed weekly using current flows and public fishing reports. Always confirm regulations, closures, and access with Colorado Parks & Wildlife or a local shop before you head out.
SECTION 01
Stagecoach Tailwater
State ParkRegulations Apply
~95CFS · Tailwater
Conditions
Dam-regulated flows keep this section extremely stable and clear year-round. Water temp near the dam stays 40–46°F. Ice-free even in winter. Historically one of Colorado's most productive tailwaters — gin-clear sight-fishing for large browns and rainbows. Access via Stagecoach State Park (day pass required).

CLOSED UNTIL FURTHER NOTICE — verify reopening with Colorado Parks & Wildlife before visiting
SECTION 02
Sarvis Creek Section
SWA — Habitat Stamp RequiredWade Only
~120CFS · Rising
Conditions
Fishing well. Flows are at ideal wading levels and clarity is excellent. Water temps 44–48°F. Located ~15 miles south of Steamboat; the Sarvis Creek SWA offers some of the best public access on the upper river. Rocks beginning to get slick — felt soles or studs recommended. Less pressure than the tailwater.
SWA — Habitat Stamp RequiredCatch & ReleaseFly & Lure Only
~280CFS · Good
Conditions
Very productive. Clarity excellent; flows slightly down from recent weeks. Catamount Lake downstream boundary. This stretch holds large rainbows and browns year-round, benefiting from catch-and-release pressure. Special regulations: artificial flies and lures only from Stagecoach Dam to Catamount Lake. Morning and evening are prime.

SECTION 04
Upper Yampa (above Steamboat)
Public Access via Hwy 131Walk & Wade
~310CFS · Dropping
Conditions
Fishing very well. The Bear River tributary adds cold, clear water. No tubing or floating allowed above town, giving wade anglers full access. Riffles, pocket water, and deeper runs. Water temp 44–50°F. Access along Hwy 131 — multiple pull-offs. Good trout density with less pressure than in-town.

Conditions
Open and fishing well. Flows at 351 CFS (down ~7% from yesterday). Clarity is great. Walton Creek downstream to the James Brown Bridge is catch-and-release with artificial flies and lures only. The town stretch offers a surprising grand-slam opportunity — rainbow, brown, cutthroat, and brook trout. Note kayakers in spring. Morning and evening are most productive.

SECTION 06
West Steamboat / Elk River Confluence
Mixed Public/PrivateWade or Float
~420CFS · Post-Confluence
Conditions
The Elk River adds significant volume and cold water here. The Elk itself is at an excellent wading level right now — clear with easy crossings in most spots. The Yampa widens and deepens below the confluence, creating excellent holding water for larger trout. Walk and wade the Elk; it's too low to float. Both rivers fish well morning and evening.

SECTION 07
Lower Yampa — Steamboat to Milner
BLM / Public AccessFloat Recommended
~500CFS · Estimated
Conditions
A transition zone where the freestone character softens. The river braids and slows, creating long flat runs with good trout holding structure. Float fishing is the most effective way to cover ground. Water temps warming into the lower 50s. Access is harder to find by foot — float trips recommended. Watch for private land boundaries.

SECTION 08
Milner Section
BLM AccessFloat or Wade
~520CFS · Estimated
Conditions
Milner marks the transition to lower-elevation water. Browns become the dominant species. Good structure in the form of undercut banks and deep bends. Warmer water temps begin to favor streamer fishing. In early April, mornings can still be cold — fish get active later in the day. Less pressure than upper sections.

SECTION 09
Morgan Bottom / Pleasant Valley
Limited Public AccessFloat Preferred
~560CFS · Estimated
Conditions
A broad agricultural valley stretch with slower, meandering character. Water temps rise more quickly here on warm afternoons. Northern pike begin appearing in slower backwater channels — great target for streamer anglers. Trout and pike can be in the same runs. Meandering bends create significant holding water. Mostly private land — float access only for much of this section.
The lower trout/warm-water transition zone. Browns dominate but pike and smallmouth bass increasingly share the water with trout. Water temps 52–56°F in afternoon — ideal for warm-season activity starting to kick in. Streamers are effective all day. Hayden town provides a put-in/take-out and limited bank access. Elkhead Reservoir influence felt further downstream.
