Issue No. 7 · Week of August 17, 2026 · The Weekly Lowdown
The trough that broke the ridge last week is gone and the valley builds straight back to 98 on Thursday. The thunderstorms went with it — there is no storm wording in our zone all week, just a 40 percent shot at showers Friday night. Dawn-only Wednesday through Friday, then Saturday and Sunday hand you back the afternoons.
Last week we told you the heat had broken. It had. It also came back, and
it came back fast. The 2 AM zone forecast has today at 93, Wednesday at 96,
and Thursday at 98 — the hottest day since the four-corners
ridge collapsed, and within a degree or two of the worst of early August.
Friday holds 96. That is three straight days when the water warms past what
a trout can pay for, and the honest read is that Wednesday through Friday is
a dawn fishery again, over by nine, exactly like the five weeks before
last.
Then it turns. Friday night brings the only real moisture in the issue —
scattered rain showers, 40 percent — and behind it the
weekend settles out: 91 Saturday, 90 Sunday, 89 Monday, with lows in the
mid-to-upper 50s. Those are not cold numbers, but they are twelve to fifteen
degrees off Thursday, and they arrive with mostly cloudy nights that let the
water shed heat overnight. Sunday morning is the best window in this
issue. If you only get out once this week, that is the one to
spend.
The other change is what left. Last week's issue was a lightning issue —
70 percent Thursday, numerous storms, get off the ridgeline. This week the
Elko zone product carries no thunderstorm wording at all for Southwest Elko
County, seven periods running. The monsoon moisture has slid south and east
of us. That means the high country is safe to spend a full day in again for
the first time in two weeks, and it means the trade has swapped back: the
thing that can hurt you this week is heat, not sky. Plan for the one you
actually have.
And then the water did something we did not expect.
The tailwater below the dam is at 6.28 cfs, up 34 percent from the
4.69 we printed last week. That is the first time this newsletter
has reported a rising number since June. It is 63 percent of the August 18
median of 10, and — this is the part worth sitting with — it is back
above the 25th percentile for the date, which we have not been
able to say all summer. The mainstem near Elko is up too, 0.45 to 0.72.
Do not read that as the drought breaking, because it is not. Not one drop
of rain has fallen in the interval. Water that appears in a Nevada river in
the third week of August without weather behind it is water somebody stopped
taking out — irrigation season winding down, a diversion closing, a change
in what the dam is letting go. That is a real improvement in what is
swimmable and catchable this week, and it is also entirely reversible. It
can go back to four and a half cfs as fast as it arrived, and one hot
irrigation decision upstream is all it would take.
What it buys you is margin. Six and a quarter cfs holds temperature better
than four and a half, and that matters in a week that tops out at 98. The
dawn-only rule still stands Wednesday through Friday — more water does not
beat a 98-degree afternoon — but the fish have more room, the seams have
more current, and the tailwater is in the best shape it has been in since
early summer. Take the win, check the gauge yourself the morning you go, and
keep the thermometer in your pack.
The best week this reach has had since June, and the first rising gauge we have printed all summer. Gauge 10320000 read 6.28 cfs and 2.23 feet at 4:40 PM, against 4.69 cfs on August 11. That is up 34 percent in seven days. The August 18 median is 10, so we are at 63 percent of normal — still under, but back above the 25th percentile of 5.8 for the first time this season, and a long way off the 2.20 record low set in 2007. Understand where it came from before you get excited. No rain has fallen. This is somebody upstream taking less out — irrigation winding down, a diversion closing, a release change at the dam — not the drought easing. It is genuinely better water and it is genuinely temporary. Check the gauge the morning you go rather than trusting this paragraph on Saturday. What it changes on the water: at 4.69 the fish were stacked in the two or three seams that still had current. At 6.28 there are more of them, they are better defined, and there is enough push to fish a dry with a dropper properly instead of dead-drifting a single fly through a puddle. Temperature still governs the day — Thursday at 98 will put this reach over 67°F by mid-morning no matter what the flow says — so it stays a first-light fishery Wednesday through Friday. Fish it the way you have all summer, only earlier. Long leaders, 6X, smaller than you want to tie on. Two feet of clear water does not forgive a heavy landing. Be on it at first light, put a thermometer in the water before you make the second cast, and when it reads 67 you are done for the day no matter how good it looks. Rainbows commonly run 14 to 22 inches here, alongside bowcutt, wild browns, smallmouth and channel cat. Access is still the constraint. The state park's water runs a quarter mile past the spillway; that is the stretch you can count on. NDOW describes fishable water some twelve miles down to Hunter Banks Diversion, but ownership below the park boundary is a patchwork of BLM and private ranch, and Nevada has no high-water-mark access right. Know whose ground you are standing on.
The high country is the whole answer Wednesday through Friday, and for the first time in two weeks you can stay all day. The thunderstorm risk that ran this section last issue is simply not in the product — seven periods, no storm wording for our zone. That removes the early-afternoon deadline we put on you last week. If Thursday is 98 on the valley floor, the cirques at 9,600 feet are running twenty degrees cooler and the walk back to the truck is no longer a gamble. That is the good news. The less-good news is that a week of upper 90s works on alpine water too, just slower. Surface temperatures at the lower lakes will climb through the week, fish will slide off the shallow shelves by mid-morning, and the dawn shift is better than the mid-morning shift even up here. Get on the water early and work deeper as the sun comes over the rim. Callibaetis are still coming off the weedy margins and the dragonfly nymphs are active in the shallows — that pair covers most of what happens at these lakes in late August. Cruisers on the inlet shelves at first light, then hang something down off the drop-offs once they leave. One access item, and it is new. The Humboldt-Toiyabe signed Forest Order 04-17-26-06-02 on August 10 covering the Mountain City, Ruby Mountains and Jarbidge districts in Elko County. It closes Forest Service Road 57390 — the roadway, the shoulder, and the ground three hundred feet out either side — from August 10 through October 31, for project work. Read the exemption carefully, because it is the whole practical difference: driving through on 57390 without stopping is allowed. Stopping, parking, or walking off the road inside that corridor is not, and a violation is a Class B misdemeanor. The order does not name the road in plain English and does not say which drainage it serves, so we are not going to guess for you. If your route into the canyon uses a numbered Forest road, call the Mountain City-Ruby Mountains-Jarbidge Ranger District at 775-738-5171 and ask whether 57390 is on it. That is a two-minute call against a two-hour drive. Otherwise access is clean. No fire closure is posted for the Ruby Mountains district — none anywhere in Elko County — and the Stage 1 restriction that has run since June 10 is unchanged. Fire danger is rated High on every district on the Humboldt-Toiyabe, ours included.
The mainstem near Elko picked up the same water the tailwater did: 0.72 cfs and 0.84 feet, up from 0.45 a week ago, against an August 18 median of 3.1. That is 23 percent of normal. Better than it was, still not a fishery — 0.72 cfs is a chain of connected puddles with slightly more water in each puddle. Same read as last week: leave it. Lamoille Creek is a different problem this week, and it is worth being precise about. The gauge has not reported since 3:55 AM on August 11. This is not the website serving a stale page — the other two gauges refreshed fine this afternoon; this one's record simply ends on the 11th. The station is dark. Its last reading was 3.18 cfs, roughly 20 percent under the lowest flow ever recorded there for that date in ninety water years of record. So we do not know what Lamoille Creek is doing, and we are not going to pretend otherwise. What we do know is that it was below a ninety-year record low a week ago and that a week of upper 90s does not raise a creek. It is possible the same irrigation change that lifted the Humboldt gauges touched it too. It is also possible it is lower. Neither guess is worth a dead fish. Our answer is unchanged: leave it until fall. The trout in there are crowded into whatever pools still hold cold water, and a stream in that condition cannot absorb a bad release. Fish the tailwater instead — this week it is not just the safer choice, it is the better water outright.
The Ely Ranger District is still closed and will be for another two weeks. We re-checked the order this morning rather than carrying last week's line: Forest Order 04-17-26-09-02, signed August 10 for the Ward Fire on Ward Mountain, closes National Forest System lands, roads and trails on the entire Ely Ranger District within White Pine County, from noon August 10 through September 1. Entering a closed area is a Class B misdemeanor. Ely Ranger District: 775-289-3031. What it does and does not cover has not changed. The order applies to Forest Service ground. Great Basin National Park is Park Service land and is not closed by it, and the order exempts private inholdings and state and county roads inside the boundary. But the approach to most Snake Range water crosses Ely District ground. Call before you commit a four-hour drive. Which makes the Jarbidge the pick of the four this week, and it is a genuinely good pick. Small high streams at 6,500 feet shed a hot afternoon far better than anything down in the valley, and with the thunderstorm risk out of the forecast the road-and-weather gamble that made us hedge last week is gone. Redband and Bonneville cutthroat will look up for a hopper through the middle of the day. Long drive, small fish, big country — which is the trade this water has always offered. Note also that the new Forest Road 57390 closure described in the Ruby Mtn Lakes section covers the Jarbidge district too — same order, same dates, same call to make. Two standing cautions. The Charleston-Jarbidge Road, CR748, is unpaved and the community road-conditions page that ranks first in search was last updated in 2021 — do not use it. Call Elko County Roads at 775-738-5036 or the Mountain City-Ruby Mountains-Jarbidge Ranger District the morning you leave. And Stage 1 fire restrictions run through October 31 on both the Humboldt-Toiyabe and the BLM Elko District, worded differently by each: the Forest Service wants chainsaw and similar work completed by 1 PM, BLM restricts internal combustion equipment 1 PM to 1 AM. Campfires in developed sites only. Bull trout in the Jarbidge go straight back in the water.
Late August is Trico season and this is a first-light week, which makes the timing almost too convenient. The spinner fall comes off early and is done by mid-morning — the exact window the heat is leaving you. Fish it dead in the film on the tailwater flats and the slow mainstem-side slicks. You are looking for noses, not rises. Go smaller than feels reasonable before you change patterns.
Peak terrestrial weeks in the high desert, and hot dry afternoons are exactly what puts hoppers in the water. This is the fly for the Jarbidge and the upper canyon pockets, drifted tight to the grass banks where the wind is knocking them in. Low-riding foam, big enough to hang a small dropper off if the fish are being coy.
The stillwater pattern for late August, when the damsel migration is finished and the big nymphs are the biggest calorie on the menu. Olive or brown, crawled slowly along the weed edges and drop-offs at the Ruby high lakes and Wild Horse. Slower than you think — this is not a streamer retrieve.
Reservoir fly, and specifically a Wild Horse fly. The trout and smallmouth there are eating young perch this month, and a flashy two-tone baitfish over the weed edge at first light gets eaten by all of them. Copper and gold. Strip it fast enough to look like it is trying to get away.
We have sent you uphill most of this summer and down to the refuge once. This week the answer is neither: point the truck north up SR225 and go fish big water. The logic is simple. The tailwater picked up a third more water this week and it is still the only moving water in the county worth a full day; the creeks behind it are at or near record lows and a 98-degree Thursday will not help them. A reservoir does not care about any of that. Wild Horse has volume, it has depth to retreat into, and it is far enough north and high enough on the Owyhee Desert that it runs a few degrees cooler than the Elko valley floor. In a week where the small water should be left alone, this is where you can actually fish hard without doing damage. Late August is also when it fishes best in a specific way: the year's perch are big enough to be worth chasing, and the rainbows, browns and smallmouth are keyed on them. Work the weed edges and the drop-offs at first light with a flashy baitfish pattern, then go to a dragonfly nymph crawled slow once the sun is up. Evenings come back after seven. It is roughly 67 miles north of Elko — a commitment, but a paved one, and the only water in this issue that rewards a full day. Know where the boundary is before you launch. The north end of the reservoir runs onto the Duck Valley Indian Reservation, and a Nevada license does not cover tribal water. See the first field note.
One email a week — the bite, the water, the wind, and where to point the truck.
