Summary: Not much change from last week. Fish are still happily taking both small flies and larger patterns like leeches and worms. A safe bet is to fish a rig with a larger pattern on top and a smaller midge or mayfly pattern on the bottom.

The Bureau of Reclamation is releasing water from what we call the "four by," which is causing the water to be off-color. Neither the fish nor we mind it though, since they keep eating away and the off-color water keeps them from noticing your leader as easily. With flows at nice 800cfs, the trout are continuing to eat larger flies. See below for full details.

Detailed Report by River Section

The Quality Waters

Overview: Nymph rigs continue to catch the most fish on this section. The fish have been eating a mix of larger flies like bunny leeches and San Juan Worms, but the water is clear enough that they also still key in on the tinier bugs. Thread midges, Big Macs, and RS2s have been working well (see fly recs at the bottom of the page). Dry fly fishing has been decent, but it’s not quite at its summer peak. Our monsoon season should help kick off the ant fall, and hoppers should come up in July and August. Streamer fishing is fair. Keep them close to the bottom and use long, slow strips.

Tips/Technique: Did you know that when we fish leeches, we’re often not imitating leeches? Midge pupae and larvae cling to moss. The trout know this and chew at passing bits of moss to extract the midges from them. This is why a natural-colored or olive leech is always a safe bet on our river: there are always some bits of moss floating downstream.

The Lower River

Overview: The lower river is by far the clearest section and is fishing well. The dry-fly fishing continues to pick up here, with a few guides scooping up solid trout on hoppers. Nymph rigs are also working well on midge, mayfly, and caddis imitations in the 18–22 range. Streamer fishing is decent here as well.

Tips/Technique: 4x tippet is OK to use here even if the water is clearer. The fish aren't nearly as pressured in this section as in the famed Quality Waters, where 5x and 6x are the norm. Fish monofilament for dry flies and fluorocarbon for nymph rigs. 1x has been our choice for streamers.

The Village

Overview: Fishing here has been consistent. We’re seeing PMDs and caddis on top of the normal midge activity. The water isn’t quite as clear as the lower river, but it’s a bit better than the quality waters, so we’re still having most of our success on nymph rigs. Prince Nymphs, RS2s, midge larvae, and San Juan Worms are all working decently.

Tips/Technique: You can still fish 4x in this section since the fish are less pressured. They're not nearly as leader-shy.
