Flows out of Palisades Reservoir got a healthy bump this morning, jumping up to 12,425 cfs. That’s a meaningful change from where we’ve been, and it’s going to reshape how you fish the river over the next several days. Much of what we talked about last week still holds — cold water, slow metabolisms, fish hunkered in the soft stuff — but now you’ve got more volume pushing through, and you’ll need to adjust your approach accordingly.
Focus on slower water becomes even more important at this flow. Buckets, tailouts, deep pools, seams, and eddies — that’s where the fish are going to be. Skip the fast banks and riffles entirely if you need to. With this much water moving, trout aren’t going to burn calories holding in heavy current. Find the soft edges, the inside bends, the slack behind structure, and work them thoroughly.
The flow bump also means it’s worm and egg time. San Juan worms (red, pink, tan) and egg patterns are getting washed into the system with the higher water, and the trout know it. Pair them with a big stonefly nymph as your anchor — a Cheater Belly, Double Bead Stone, or 20-Incher in sizes 4–8 will get your rig down where it needs to be and give fish a reason to eat on the dredge. Add a smaller dropper — a zebra midge or pheasant tail in 16–20 — if you want to cover your bases.
The weather: not pretty, but the fish will love it
Bundle up, because this is going to be a cold, wet stretch. Today brings snow showers in the afternoon with a high near 37 and west winds gusting to 28 mph. Tonight’s more of the same with another inch or so of snow. Friday doesn’t improve much — high near 33, more snow showers, possibly some thunder mixed in. Saturday finally offers a break with mostly sunny skies and a high near 45, which will be the most pleasant day to be on the water by a long shot. Sunday slides back into snow before noon with a high near 45 and some thunder possible.
Here’s the silver lining: streamer fishing should be excellent in this weather. Dark skies, cooler temps, and stained water coming in with the flow bump are exactly what a streamer angler wants. Focus your swings and strips along slower banks, drop-offs, side channels, and — don’t sleep on this — “frog water,” or stretches that barely appear to be moving at all. Fish will stage in that dead water when flows come up, and a well-presented streamer stripped through it can draw the biggest eats of the day. Olive, black, and white sculpin patterns, small Dungeons, and Godzilla are solid bets. Get it down with a sinking tip and work it slow.
