Issue No. 4 · Week of July 27, 2026 · The Weekly Lowdown

South Fork is closed. Go high.

Five fires in the county put aircraft on the reservoir and smoke in the valley, and State Parks closed South Fork to boats Tuesday morning. Add a heat ramp that tops 100 by the weekend and the week comes down to one honest option: get above the smoke, early, on foot.

The Lowdown

This is a fire week, not a fishing week. Nevada State Parks closed South Fork Reservoir to all boating Tuesday morning, until further notice, so firefighting aircraft can dip out of it. Five fires are driving that call — the Chimney Fire at 21,000 acres and zero containment near Snowstorm Mountain, the Secret Pass Fire at 3,165 acres and zero containment near Humboldt Peak, plus the Boyd, Long Canyon, and Hoppie Basin fires. The state recreation area is still open for everything except the water. The air is the other story. NWS Elko has high confidence that smoke from Elko County and southern Idaho fires keeps hurting visibility all week, with northerly overnight flow filtering it back into the valley for smoky mornings. And the heat is still coming — mid-90s early, then a prolonged event with better-than-75% odds of triple digits Friday through Sunday. Meanwhile the Humboldt is at 2 cfs. High country, first light, on foot, and check what's burning before you drive anywhere.

Water Conditions

Ruby Mtn Lakes — Lamoille Canyon

AccessOpen · verify first
AirSmoke haze
Surface Temp66°F lower
Upper Lakes58°F

The high lakes are the week, with a caveat: fire activity in the county is changing daily and the Secret Pass Fire is burning uncontained in the East Humboldts to the north. Check the forest and InciWeb before you commit to the drive. If the canyon is open, the elevation split still holds — lower lakes at 66°, the upper basins near 58° and fishing well. Climbing also gets you out of the worst of the valley smoke, which is worth as much as the cold water this week.

Reservoirs — South Fork & Wild Horse

South ForkCLOSED to boats
Wild HorseOpen · no dock
Wild Horse LevelDown ~20 ft
Surface TempMid-high 70s

South Fork is closed to all boating until further notice — State Parks announced it Tuesday morning so aircraft can dip. Do not launch, and do not go looking for a workaround; those pilots are working a 21,000-acre fire. Bank access and the rest of the recreation area remain open. Wild Horse is open, with one thing to know before you hitch up: the floating dock came out July 24 and stays out until next spring. The ramp still works, but the water is down about twenty feet and you'll be launching off bare concrete. Algae is growing fast and the surface is mid-to-high 70s, so the trout are done here either way — this is not the week to press it.

Rivers & Streams — Humboldt & Lamoille Creek

Elko Gauge2 cfs · 33%
Carlin Gauge3 cfs · 20%
Basin2% of normal
LamoilleFirst light only

Two cubic feet per second past Elko, three past Carlin, and the river as a whole at 2% of its seasonal average. There is nothing to fish for down there and nothing worth killing to find out. Lamoille Creek out of the canyon is the one moving-water option left, and it is strictly a first-light fishery — thermometer in the pocket, done at 67°F, and that number arrives earlier every week.

Native Waters — Jarbidge & the Snake Range

RoadsDry · check fire status
ClarityClear
Water Temp58°F
StatusWild · C&R

Still the coldest water in the region, but this is the week to do your homework before a four-hour drive on dirt. New lightning starts were in the forecast early in the week and the county already has five fires going. Confirm your route is open, tell someone where you're going, and carry more water than the trip should need. Redband and Bonneville cutthroat are eating hoppers in the shade at 58°. Bull trout in the Jarbidge go straight back.

The Fly Box

Dave's Hopper
#8–10 · dry

Peak grasshopper. Hot, dry, cured-out bank grass means the naturals are everywhere and clumsy. Slap it — don't present it — a foot off the grass on Lamoille Creek and along the windward banks of the high lakes.

Griffith's Gnat
#18–22 · dry

For the flat, glassy first light on the alpine lakes when fish are dimpling on midge clusters and refusing everything bigger. Tiny, drab, dead still. Grease the leader and watch for the sip rather than the take.

Parachute Adams
#16–18 · dry

Smoke does one useful thing: it flattens the light and cuts the glare, and fish stay looking up later into the morning than they would under a hard sun. A drab general-purpose parachute covers that window better than anything specific.

Copper John
#14–18 · dropper, 10–14 ft

When the surface shuts off, this is how you keep fishing the upper lakes. Red or copper, hung deep off the shelf edges. Heavy enough to get down without a split shot fouling your presentation in gin-clear water.

Hot Spot of the Week

Lamoille Lake
Ruby Crest Trail · ~9,700 ft

No boat, no ramp, no closure to worry about — a short walk from Road's End at the top of Lamoille Canyon and you're at 9,700 feet in cold, clear water. That is exactly the right shape of trip in a week when the reservoirs are shut to aircraft and the valley is full of smoke. Brookies work the drop-offs and the inlet at first light. Start early, take the elevation for the cleaner air as much as the fishing, and confirm canyon access before you leave town.
