Issue No. 1 · Week of July 6, 2026 · The Weekly Lowdown

Dog days, dawn patrol.

The valley floor bakes into the 90s while the Ruby high country stays cool and turned on. Climb for the bite, and be off the water before the heat and wind stand up.

The Lowdown

Full-on high-desert summer now. The valley is running hot — expect mid-90s by midweek — so the fishing has moved uphill with the snowline long gone. The Ruby and East Humboldt high lakes are cool, ice-free, and eating, while down low the Humboldt runs thin and warm through the afternoon. The play all week is the same: be on the water at first light, then chase shade and elevation as the sun climbs.

Water Conditions

Ruby Mtn Lakes — Lamoille Canyon

AccessOpen
ClarityGin
Surface Temp58°F
TrailClear

Island, Liberty, and the Dollar Lakes are in peak summer form. Brookies cruise the shallows at dawn, then chironomid emergences stack fish mid-morning. The last snowbanks are gone from the upper trail — easy walking now.

Reservoirs — South Fork & Wild Horse

LevelSteady
ClarityLight Stain
Surface TempLow 60s
TrendWarming

Trout have slid deeper as the surface warms — work damsels and leeches along the weed lines at first light, then go down. Wipers are busting bait on calm mornings at South Fork; keep a streamer rigged and ready for the boil.

Rivers & Streams — Humboldt & Lamoille Creek

Humboldt FlowVery Low
ClarityClear
Water TempWarm PM
LamoillePrime

The Humboldt is thin and warming through the valley — fish the cool dawn hours only, then rest it. Up in the canyon, Lamoille Creek is in prime shape: pocket water and shade lines are holding fish. Carry a thermometer and back off past 67°F.

Native Waters — Jarbidge & the Snake Range

RoadsDry
ClarityClear
Water Temp56°F
StatusWild · C&R

Backcountry redband and Bonneville cutthroat are looking up for dries. Long drives, small fish, big country — wet hands, quick release, and mind the bull trout closures up the Jarbidge.

The Fly Box

Chironomid
#14–18 · 8–14 ft

The alpine-lake workhorse right now. Mid-morning emergences are stacking fish — match the olive and black bombers, and fish them deeper than you think.

Balanced Leech
#10–12 · under indicator

Black or maroon, hung 8–12 ft down off the drop-offs at the Ruby lakes and the reservoirs. Let the chop do the jigging for you.

Hopper-Dropper
#10 hopper / #16 dropper

Desert stream season is peaking. Bank-tight drifts on Lamoille Creek — the dropper does most of the work, but they'll come up and crush the foam.

Damsel Nymph
#10–12 · slow strip

Reservoir staple as the weeds green up. Olive, twitched along the edges at South Fork and Wild Horse early, before the wind gets on the water.

05

Hot Spot of the Week

Angel Lake
East Humboldt Range · ~8,400 ft

This glacial cirque above Wells is fishing as good as it gets all year. Cruisers patrol the inlet shelf at dawn, and the drive up the switchbacks is worth it on its own. Bring layers — it can be 45° at the launch while the valley bakes in the 90s.
