Big reservoir up in the Lassen country, and the whole calendar bends around one thing: the early-summer Hexagenia hatch. Those big mayflies come off at last light in June, and the browns and rainbows that ignore you all day suddenly lose their composure — be on the water at dusk or don't bother coming. The rest of the year you fish the cold-water "springs" lies with damsels, leeches and streamers. It fishes year-round, but June evenings are the event everyone drives in for.
Hot — dawn and dusk onlySustained heat. Fish deep, handle carefully, stop if a fish struggles.
The air has been hot long enough for the whole surface to be warm. There is no water sensor here, so we cannot tell you the depths are safe — only that they are the most likely place to find a few cool degrees if the water is deep enough. On the big reservoirs and Highland lochs the cool layer sits at four to ten metres, but late-summer oxygen losses can narrow it. On shallow club fisheries under five metres there is no refuge. Fish dawn and dusk only or rest the venue. Barbless hooks. Land it fast. Wet hands. No air shots. If a fish swims off slowly, rolls, or needs more than half a minute to revive, stop. That is the welfare signal — not the temperature.
- DepthDeep waters: a fast sinker to four to ten metres, but watch the colder deeps for poor oxygen late in the season. Shallow fisheries: no refuge. First light, last light, or come back another day.
- TimingTwo hours after dawn and the hour before dark. Nothing else. The real stop signal is the fish on release — if recovery is slow, stop.

How to fish it · for brown trout
When
No strong hatch signals at the moment — general searching tactics should work best. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Today's tactical plan
The plan
Plan A · Plan B · what to watch · bank or boat
The plan
Plan A
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
