Public scales on I-84 along the Columbia River (Biggs, Boardman & Stanfield)
Three CAT Scales verified on the operators’ own location pages along I-84 east of The Dalles: Pilot #195 at Biggs Junction (Exit 104, where US-97 crosses the river), Love’s #650 Boardman (Exit 159), and Pilot #390 Stanfield (Exit 188, at US-395 between Hermiston and Pendleton). Useful for U-Haul and PPM moves into the Hermiston–Tri-Cities area, RVs and fifth-wheels running the Gorge, and horse and stock trailers out of wheat and ranch country. Pilot says Stanfield has store work underway, so call before you drive there. East over the Blue Mountains, see Ontario / Baker City / I-84; west, see Portland / Troutdale; north across the river, see Pasco / Prosser / Tri-Cities.
This page lists 3 places to weigh near Biggs, Boardman & Stanfield, OR: 3 CAT or truck-stop scales. They are in Wasco (Biggs Junction), Boardman and Stanfield. 3 are listed as likely to print a certified weight ticket, the kind PPM movers and RV owners checking weight ratings usually need. CAT platforms have a 2,000 lb minimum and do not give corner weights.
Filters hide cards, not industrial rows. CAT will not weigh under 2,000 lb — use a dedicated house for cars and empty utility trailers.
No verified dedicated public scale house in Sherman, Morrow or Umatilla County tonight
We have not found a walk-up public scale house in Biggs, Arlington, Boardman, Hermiston, Stanfield or Pendleton with an operator page we can cite, and ScaleRegistry’s public-weighing page lists none in Oregon. We are not inventing one from grain elevators, potato sheds, feedlots, landfill gate scales, or third-party trucker directories. All three stops below are CAT Scales at truck stops, verified on Pilot’s and Love’s own location pages.
CAT Scales at Biggs, Boardman and Stanfield
We list only stops verified on the operator’s own location page. Pilot #195 Biggs and Pilot #390 Stanfield list CAT Scale among their store offerings and say Open 24 Hours; Love’s #650 Boardman lists CAT Scales and a store open 24 hours. Those are store hours, not a published CAT-staffing schedule. Pilot posts a “store enhancements underway — some amenities temporarily unavailable” notice on the Stanfield page, so confirm the scale is in service first. 2,000 lb floor. No corner weights. Weigh the whole rig, then drop the trailer and weigh the tow vehicle for the trailer number. Do not unload horses at a truck stop. Oregon weighmaster rules differ from California — confirm ticket needs with your TO or licensing office. Use CAT’s locator for other stops.

Pilot’s own Stanfield page lists CAT Scale, bulk and cylinder propane; I-84 Exit 188 at US-395 (Umatilla County), between Hermiston and Pendleton.

Oregon DOT weigh stations and ports of entry on I-84 are for commercial vehicles — not a place to buy a civilian weighmaster ticket for a U-Haul, RV, boat, horse trailer, or PPM load. Follow posted signs; do not treat this directory as a bypass guide.
What we still need to verify
Any dedicated public scale house in Boardman, Hermiston, Pendleton or The Dalles with an operator page that sells walk-up weighmaster certificates. CAT-scale staffing hours at all three stops (only store hours are published). Whether Stanfield’s scale is affected by the store work Pilot mentions. Flying J #934 La Grande (Exit 265) does not list CAT Scale in its own offerings tonight, so it is not on this page. No Pendleton or Hermiston CAT has been verified on an operator page. Livestock policy everywhere.
