If you live here, you already know the third week of August is not a normal week. What you may not have thought about is why the county's biggest social event and its biggest economic event happen at the same address on the same days, and what that overlap actually costs you if you plan around it badly.
My claim for this post is simple. The Sherman County Fair is not scheduled next to harvest by accident, and reading the week as a single machine, rather than two separate things, is what separates a resident who enjoys August from one who spends it stuck behind a grain truck on Highway 97. This year the machine runs August 17 through 23, and the wheat side of it is running hotter than it has in years.
Why this week, and not another
The fair board describes the timing plainly on the county's own page: this is "Sherman County's largest annual gathering, scheduled for when the planting season winds down," on the Flats of Moro within walking distance of downtown. That phrase does a lot of work. The county's dominant crop, soft white winter wheat, is planted in the fall and harvested in July and August, with roughly 110,000 acres going in each fall on Sherman County ground alone. The fair sits in the seam between the last combine pass and the first fall tillage, when families can actually leave the field.
The scale of that seam is bigger this year than most. Growers across Wasco and Sherman are commonly reporting 90 bushels per acre or better on 2026 fields, and cash wheat has climbed to about $6.75 per bushel, roughly fifty cents above last summer's peak. For context, Oregon's statewide winter wheat average was 71 bushels per acre in 2025, and the four-county Mid-Columbia block of Wasco, Sherman, Gilliam and Morrow planted about 357,000 acres of soft white winter wheat in 2025, close to half of Oregon's entire winter wheat footprint that year. That is the money that pays for the trailers, the show clothes, and the auction bids you will see at the fairgrounds this month.
Ninety bushels an acre at roughly $6.75 a bushel is the kind of pairing local growers rarely see land at the same time. When it does, the fair's livestock auction on the following Saturday feels different in the ring.
The fairgrounds week, in order
The 2026 4-H & FFA Fair Book from OSU Extension sets the fair at August 17 through 23 at the Sherman County Fairgrounds in Moro. Reading it as a week rather than a "come Saturday" event is the local move.
| Day | What's happening | What it means for a resident |
|---|---|---|
| Mon Aug 17 – Tue Aug 18 | Setup, exhibit entries in the event building | The Flats are quiet; museum and downtown Moro are still normal |
| Wed Aug 19 | Official livestock weigh-in for market animals | First heavy trailer traffic on the fairgrounds road |
| Thu Aug 20 | Small animal shows, exhibits open | Best day for a walk-through without crowds |
| Fri Aug 21 | Rodeo evening, music, concessions | Parking on the upper gate side fills after 5 p.m. |
| Sat Aug 22 | Parade, Grand Champion showmanship, rodeo, Sherman County Youth Livestock Auction | The one day the whole county is in Moro |
| Sun Aug 23 | Load-out, cleanup | Highway 97 sees the last of the trailer traffic |
Sale order at the youth livestock auction rotates each year through goats, poultry, swine, sheep, and beef. If you have never gone as a buyer, Saturday is the day. If you have never gone at all, Thursday is a better first visit than Saturday, because you can actually see the animals and talk to the exhibitors without the crush.
What Moro looks like the rest of the week
If you live in Moro, this is the week your neighbors bring you visitors and expect you to have a plan. A plan that is not the fair helps.
The Sherman County Historical Museum sits a block from the fairgrounds walk-in at 200 Dewey Street. It has run as a national-award-winning small museum with rotating exhibits, tours, and hands-on programs. In past fair weeks the museum has staged an exhibit at the fair itself, in the 4-H pavilion, which is a fair-week ritual worth pairing with the ribbon aisle in the same building. Moro City Park adds the Wall of History and public restrooms if you have people who need a break between the fairgrounds and downtown. The 1899 courthouse sits above the town and is the postcard shot most out-of-town guests will ask about.
Two blocks in another direction, the Sherman Experiment Station keeps 234 acres of OSU dryland research on wheat, barley, canola, and other alternative crops. If your guest asks why the hills look striped, that is your answer: summer-fallow farming, half the field held out of production so the soil can bank moisture for the next crop on the county's 11 inches of annual rain. It is the reason the yields you are hearing about this month exist at all.
The Wasco and Grass Valley detours
The fair pulls attention to Moro, which means the rest of the county is quieter than usual. Use it.
Wasco is nine miles up Highway 97 and worth a lunch trip during fair week for exactly that reason. The Dirty Cowgirl Saloon anchors downtown, the Columbia Southern Railroad Depot and its retired caboose sit on the National Historic Register a short walk away, and the city hall stocks a self-guided walking tour map that covers the depot, Oregon Trail crossing signage, and the buildings that survived the town's earlier grain-boom decades.
Grass Valley, another leg south, is the run to make on a Wednesday evening when the fairgrounds are still setting up. Grass Valley City Park is the shade in a county that does not have much of it, and the EV charging station at the Grass Valley Country Market has quietly turned the town into a working stop for people driving Highway 97 through the summer. If you drive an electric vehicle out of The Dalles, this is the useful mid-county charger residents already know about.
Where the grain actually goes
Watching where the trucks turn is the other layer of the week most residents drive past without registering.
Mid-Columbia Producers Cooperative operates the grain storage elevators you can see from Highway 97 in Wasco, Grass Valley, and Kent, with the biggest facility at Biggs where rail and barge meet the river. The trucks running past your driveway in August are moving between those points. From Biggs and from the Port of The Dalles, wheat feeds the Northwest Grain Growers export terminal on Bargeway Road, where a new scale system this year has meaningfully sped up truck turnaround. The terminal has been busy through the 2026 harvest, and it also hosts trade delegations from Japan and South Korea in the same weeks locals are hauling. That is the export end of the same crop your neighbors are auctioning off at the fair on Saturday.
If you want to see the physical end of the pipeline without leaving the county, Giles French Park sits below the John Day Dam on the Columbia and gives you the barge lane from the shore. It is a good sunset drive after a fair-day afternoon.
A quiet Monday plan before it all starts
For anyone who wants to enjoy the week without spending it in a crowd, the Monday before the fair is the underused day in Sherman County. Here is a compact plan:
- Coffee in Moro, then a short walk past the 1899 courthouse to the museum on Dewey Street before the fair-week exhibit rotation begins.
- Drive south on Highway 97 to Grass Valley City Park for a picnic, with a top-up at the Country Market charger if you need it.
- Loop back through Kent to see the grain elevator most people never stop for.
- Head north to Wasco for an early dinner at the Dirty Cowgirl and a walk to the railroad depot before the light drops.
- End at Giles French Park below the John Day Dam if the wind has settled.
You will have covered every incorporated town in the county before the fairgrounds gates open on Wednesday morning.
The through line
Sherman County has about 1,955 residents spread across six towns roughly nine miles apart, with an economy built on wheat, barley, cattle, and a growing amount of tourism traffic on Highway 97. In most weeks that geography feels spread out. Convergence week is the one time it collapses to a single address in Moro, and the reason it does is that the crop and the community share a calendar older than any of us. Read the calendar and August makes sense. Ignore it and you spend the week in traffic.
