Best Flies for Hat Creek (California)

Hat Creek's Wild Trout section is a spring creek with a reputation that outruns most visiting casts. Fish are on midges, PMDs, and Tricos more than on the fly you bought because it looked good in the bin. Long leaders, small flies, and a willingness to nymph the same lane are the job. The hatch table below is the editorial chart for Hat Creek, not a live trap report.

This is not a live report of other anglers' catches. Presence and flow live on the Hat Creek river page and the California destination guide.

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 Hat Creek. 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

5X and 6X fluorocarbon on nymphs, 5X on dries unless the fish are on Tricos, then 6X or 7X. 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 Hat Creek?
Start with BWO Sparkle Dun and BWO Parachute, then match size to the hatch chart for the month you are standing in. The Hat Creek 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 Hat Creek?
The editorial window we list is May, June, July, September, October. 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 Hat Creek?
California 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 Hat Creek?
Open the Hat Creek 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 We do not publish other people's spots or fish counts.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 Hat Creek?
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.
