Hatch-chart pattern list
Best Flies for Clearwater River (Idaho)
The Clearwater River in Idaho fishes as both a wade and a float. It is a freestone fishery for Steelhead and Chinook Salmon, with the most reliable window in April, May, September. The patterns below are matched to the hatch chart we publish for this water. They are not a live report of what other anglers caught this week.

Nymphs
Subsurface patterns matched to this river's chart and catalog. Fish them at the size the chart lists, not the size that looks good in the bin.
Dries
Dries and terrestrials for the Clearwater River. If the chart says a size 18 PMD, do not start with a 12.
Streamers
Streamers and wets for stained water, banks, and low light. This is not a claim that streamers are "on" today.
No catalog patterns in this group yet. Use the hatch chart and the river guide.
Setup
4X and 5X cover most nymphing. 4X on dries until the fish get picky, then 5X. A 3.0–3.8mm tungsten on the point and a lighter dropper is a default until you see the water. Tight-line the near bank and the heads of pockets. Use an indicator only when you need to search water you cannot euro.
FAQ
- What flies work on the Clearwater River?
- Start with BWO Parachute and Parachute Hopper, then match size to the hatch chart for the month you are standing in. The Clearwater River does not need a 40-pattern box. It needs the right size on the insect that is actually in the drift.
- When is the best time to fly fish the Clearwater River?
- The editorial window we list is April, May, September, October, November. That is a planning month range, not a guarantee. Shoulder months can fish well if flows and water temperature cooperate.
- Do I need a guide on the Clearwater River?
- Idaho has walk-up wade water and, on some sections, float water. A guide is worth it for a first float or a technical tailwater. A hatch chart and a gauge are enough for a first wade if you already nymph. We list local guides and shops on this page when we have them.
- Where can I see live flow for the Clearwater River?
- Open the Clearwater River river page for the USGS gauge, access notes, and the same hatch chart this fly list is built from. We do not publish other people's spots or fish counts.
- Is this a report of what's working now on the Clearwater River?
- No. Executive Angler does not publish other anglers' catches, GPS, or a crowdsourced hot fly. This page is hatch-chart patterns plus catalog flies. Presence on the river page is gauge and weather only.
