Two-Week Rainfall

Observed (prior 14 days) and forecast (next 14 days) · Sanders County · as of 2026-08-01

Observed detail: 0 measurable-rain day(s) in the prior two weeks; largest single day 0.00 in.

Forecast source: NWS/NOAA api.weather.gov (days 1–7) blended with Open-Meteo gridded model (days 8–14). The next-14-day total is model-derived — NOAA quantitative precipitation forecast is precise only through ~7 days, and days 8–14 are a model blend, not an observed gauge reading.

Water Rights, Irrigation & Land Ownership

The Clark Fork River crosses Sanders County west from Thompson Falls toward the Idaho border, collecting the Thompson River at Thompson Falls and numerous Cabinet Mountain tributaries en route. The Thompson River drainage, running south from the Cabinet Mountains, is the most agriculturally significant sub-basin in the county.

Water rights in Sanders County are modest in scale and largely uncontested due to high natural flow relative to demand. The oldest rights on the Thompson River and Horse Plains area date to the 1880s–1900s. Irrigation is almost entirely small-scale flood or gravity-flow on creek-bottom hay meadows, with very limited pivot or sprinkler infrastructure. The basin is not over-appropriated in normal or above-normal years, but late-season low flows in the Thompson tributaries can trigger informal pressure on junior rights in dry Augusts. Groundwater wells support most stock water needs above the valley floors. Flathead Lake backwater does not meaningfully extend into Sanders County’s water rights picture.

Federal Grazing Leases

BLM and U.S. Forest Service permitted grazing on public-land allotments · Sanders County

AUMs (BLM) and head-months (USFS) are both animal-unit-months — one animal grazing for one month, the standard measure of authorized use. Acres are BLM public acres and USFS GIS acres on the mapped allotments.

Statewide maps: BLM allotment map · Forest Service allotment map. Excludes Montana DNRC state-trust grazing leases.

Land Resources

Three independent estimates of how Sanders County’s land is used — shown side by side, never blended

Every acreage figure below comes from an independent source that measures the land a different way. We show them side by side — and never blend reported acreage, satellite pixels and tax classifications into one unexplained number. Total county area 1,766,656 acres · land in farms 621,625 acres (35% of the county).

Principal crops — official vs. satellite

These columns measure different things, so they should not match. The Census counts acres actually harvested in the census year, as reported by producers; the Cropland Data Layer counts every acre the satellite saw in that crop, including fields in a crop–fallow rotation and stands not harvested. Winter wheat is the clearest example: much of the county’s wheat ground sits in fallow in any given year, so the satellite total runs well above harvested acres. CDL also over-attributes hay and forage on native range. “Withheld” means the Census suppressed the value to protect an individual operation’s privacy.

How the county’s acres classify

Three ways of counting the same ground. Census figures are producer-reported acres in farms; the satellite column is a wall-to-wall pixel classification of the whole county (so it also sees developed land, water and non-farm ground the others do not); the assessment column is the Montana Department of Revenue’s parcel-level tax classification (CAMA), which is why its cropland total tracks the Census closely while the satellite tends to run higher. Developed and open-water rows come only from the satellite. Where they disagree, no single number is “wrong” — they are measuring different things.

Irrigated land, three independent ways

The single most important acreage figure for a cattle operation, and the three sources genuinely differ. The Census counts acres actually irrigated and harvested in the census year; the Montana DOR figure is what is classified and taxed as irrigated; the DNRC mapping captures the full remote-sensed irrigated extent, including ground that carries irrigation but was idle or in another use that year — so it usually reads highest. We publish all three rather than pick one.

What each estimate means

• USDA Census of Agriculture — producer-reported, the official record. Highly credible, but taken every five years and suppressed in counties where a value would identify a single operation.
• Satellite (Cropland Data Layer) — USDA’s annual, wall-to-wall satellite classification. Complete county coverage every year, but it infers crops from imagery, so it mislabels some ground and over-calls hay and forage on native range.
• Tax / assessment — Montana Department of Revenue parcel-level classification from the CAMA assessment roll (2026 tax year), aggregated from the Montana State Library cadastral. Parcel- and ownership-based; a land classification, not an annual crop report.

Production & Sales

Operation character, hay base, and how cattle reach market from Sanders County.

Cattle production

Sanders County runs a mix of small family cow-calf outfits and larger timber-range operations using national forest allotments. The Plains and Hot Springs areas hold the most concentrated ranching activity; Thompson Falls serves as the county seat and agricultural service center. Operations typically run 50–200 cows on a combination of deeded meadow ground and USFS allotments. Some backgrounding occurs but most calves sell in fall at weaning. Elk competition for forage on allotments is a recurring issue in the Cabinet foothills.

Hay & winter feed

Native grass hay and grass-alfalfa mixes are cut from irrigated creek bottoms along the Thompson and its tributaries. Most operations get one reliable cut per year; a second cut is possible in wet years on lower-elevation ground near Plains. Many operators supplement with hay purchased from Lake County’s Flathead Valley farms. Feed costs are a significant operating variable given limited local production capacity.

Logistics · sale barns & trucking

MT-200 is the primary east-west corridor connecting Plains and Thompson Falls to Missoula (90 miles) and north to Polson. No sale barn in Sanders County; operators truck calves to Missoula or Ronan for sale. Fall gather from forest allotments typically runs September–October before snows close upper USFS roads. Trucking to Spokane is about 2 hours west on MT-200 to US-2.
