Flow Is Right in the Window — but Watch Afternoon Wind and Water Temperature
At 104 CFS, Dream Stream is sitting dead center in its productive band (100–250 CFS), and that’s genuinely good news for wading and drift control this week. You’re in that sweet spot where you can cross the meadow channels without fighting current, hold a tight line to the bottom, and — critically — keep fish from spooking at the first flicker of shadow across open water. The tailwater release from Spinney is steady enough that you won’t fight violent speed changes mid-drift.
But here’s the catch: 104 CFS on an exposed, treeless three-mile strip means you’re fishing in a wind tunnel with zero buffering. The afternoon thermals that sweep South Park will flatten your dries and drag your indicator all over the place. Water temperature is climbing into the low 50s by mid-afternoon (typical for June on this tailwater), which matters — it’s still cool enough that fish are active all day, but it’s the beginning of the season’s warmth creep. Get on the water early, fish hard until the afternoon gusts really spike around 2 p.m., and don’t feel bad about wrapping up by 4 p.m. Fish welfare and your casting sanity will both thank you.
PMD Season Is Here — Fish the Emerger Window Hard
Pale Morning Duns are the marquee hatch on Colorado tailwaters in June, and Dream Stream is no exception. Expect genuine emergence between 10 a.m. and 2 p.m., with the heaviest activity from 11 a.m. to 1 p.m. The bugs will be #16–18, and the duns themselves are the visual event — pale yellow-olive bodies, neutral wings, and they’ll be sitting on the water long enough that fish will rise to them. But the real meat is in the emerger phase, just before and during the hatch. Fish eat more emergers than duns, especially at 104 CFS where fish can afford to be selective without gulping everything off the surface.
Caddis will show up in the evenings (#14–16), but don’t lean on them yet — the water temp hasn’t spiked high enough for evening caddis to dominate. Midges, as always on a tailwater, are working all day long. Black Beauty and zebra-midge patterns in #20–24 are never a bad call, particularly in the early morning before the PMD hatch kicks in and in the slow, deeper pockets where fish will graze on small stuff between hatches.
The Rig That Works Right Now
Start your morning with a midge dropper before the PMD emerger hatch kicks in. Tie a #22 Black Beauty or Mercury Midge (any realistic small-midge pattern) as your point fly on 5X tippet. Add 12–18 inches of 6X above it and tie on a #18 PMD emerger — a CDC pattern or a slender nymph like a Barr-style emerger in pale olive works best. Add a single small split shot about 8 inches above the point fly to get you to the bottom of the deeper slots without dragging.
Use a small indicator — just enough yarn or a tiny foam dot to see the drift — positioned about 3–4 feet above your top fly. At 104 CFS, you don’t need heavy weight or a bulky setup; the current will help you maintain depth without constant mending. Fish tight to the bottom in the deeper seams and current breaks. When you see the indicator dip, set immediately — at this flow, takes are unmistakable, and hesitation costs fish.
Once the PMD hatch starts (around 10:30 a.m.), you have two options: switch to a dry-dropper rig with a #16 PMD dry and keep the #18 emerger below it on 18 inches of 6X, or stick with the full nymph rig and fish it shallower (move your indicator up to 2.5 feet). The dry-dropper is more fun and easier to see in wind, but if the afternoon wind really cranks, the nymph rig will be more reliable. Either way, fish the slower, deeper runs where PMD nymphs hold before emergence — the long glides on both sides of the meadow channels, and anywhere the current breaks around slightly deeper water.
Which Water to Fish
Dream Stream’s meadow character means you’re looking for subtle depth changes and current seams, not obvious structure. The deeper runs along the inside of gentle bends will hold more fish than the shallower, faster water. Because there’s no tree cover or canyon shelter, every piece of water is equally exposed to wind, so pick where the fish actually hold: slower water, deeper slots where the current eases off. At 104 CFS, these pockets are easy to wade into without fear of getting swept, so don’t be afraid to work methodically through the deeper sections.
Avoid fishing directly over visible redds (spawning areas); spring lake-run fish are long past spawning here by June, but stewardship counts. If you see gravel beds with dug-out depressions, skip over them.
Early and Late; Skip the Blow
Fish hard from first light through noon. The PMD hatch will be happening, midges will be active, and the wind will be manageable. After 2 p.m., the exposed meadow becomes a wind-beaten endurance test, and fish become more concentrated and spooky under bright sun and gusts. You’ll catch more in three focused morning hours than you will pushing through four afternoon hours fighting wind and heat.
Water temp is still cool enough that early and late-day fishing doesn’t offer a dramatic advantage over mid-morning, but every degree of warming that comes through June will shift that calculus. For now, the PMD hatch timing is your schedule — fish it, then take it easy.
