Hay & Pasture — Greenness Now Greenness: High · 95th percentile vs local normalA current satellite greenness read (last 16 days) of this county’s managed hay & pasture ground (NLCD class 81), versus its own history. It can run ahead of or behind snowpack and streamflow — read it alongside those tiles, not instead of them. Updated weekly.
How often this updates. The moisture and drought tiles below — snowpack, streamflow, soil moisture, rain, water-year precipitation, and drought class — refresh every morning. The Forage Condition score’s satellite vegetation read, and the separate Hay & Pasture read, refresh weekly (Mondays), because the underlying satellite imagery (RAP herbaceous biomass and MODIS NDVI; until the current season’s RAP publishes, a soil-moisture proxy stands in for the vegetation input) only updates on a roughly 16-day cycle. So the water and drought tiles move day to day, while the vegetation and hay-pasture reads step forward about once a week — a dry spell shows in the moisture tiles within a day, but takes a week or two to register in observed greenness.

Reading this dashboard — what these terms mean

Median vs. mean. We use the median (NRCS standard) so a single very-wet or very-dry year doesn’t skew the baseline.

Water year. Hydrology runs Oct 1 → Sep 30. Most of a year’s snowpack accumulation is captured in the same season it melts.

Percentile (streamflow). 50 = exactly typical for this calendar date. 19 = today’s flow is lower than 81 % of all readings ever recorded on this date. 81 = lower than only 19 %.

VWC (soil moisture). Volumetric Water Content. Rough field bands: under 10 % = dry, 15–25 % = productive growing-season range, over 35 % = saturated.

Drought scale. D0–D4 from the U.S. Drought Monitor, weekly Thursday release. The percentages tell you what fraction of county area is at or worse than each band — a county can be 100 % at D2 with 0 % at D3.

Precip anomaly. Inches above or below the 1901–2000 average for the latest completed 1-, 3- and 12-month periods (NOAA NCEI Climate at a Glance, monthly data). Not the water year — the Water-Year Precip tile is the water-year measure. Anomaly is in inches; “% of median” is a ratio. Both useful; anomaly is easier to interpret when comparing a dry summer month to a wet spring month.

Forage Condition. A 0–100 county-scale index of rangeland forage conditions relative to this county’s own historical normal, blending satellite-observed vegetation response, growing-season moisture, drought stress, and usability. Higher = more favorable relative to local normal. Categories: 0–25 Poor, 26–50 Fair, 51–75 Good, 76–100 Excellent. Long-Term Forage Potential is a separate long-run rating, not part of the score. Beta — for regional screening and comparison, not a pasture-level forage inventory or stocking-rate recommendation.

How often this updates. The moisture and drought tiles (snowpack, streamflow, soil moisture, rain, water-year precip, drought class) refresh every morning. The Forage Condition score’s satellite vegetation read — and the separate Hay & Pasture read — refresh weekly (Mondays), because the underlying satellite imagery only updates on a ~16-day cycle. So the water tiles move day to day; the vegetation reads step forward about once a week.

Snowpack & Moisture Detail

SNOTEL station-by-station read for Sanders County. The dashboard above gives current aggregate; this section shows where the water actually is.

Sanders County snowpack is at or above median at all 3 reporting stations at the last spring reading (June 4, 2026). Snowpack has since melted out for the season, so this section shows how the 2026 snow season ended, not current conditions. Three SNOTEL stations monitor county snowpack. Sanders County watershed snowpack near or above normal (county avg 104% of median); highest at Chicago Ridge (129%), lowest at Sleeping Woman (88%).

Station snapshot as of September 17, 2026 — live dashboard above is current.

Rancher implication. As of September 17, 2026: moderate drought (D1) covers 5% of Sanders County; the past two weeks of rainfall ran near normal (104%) and the next two are forecast well above normal (144%), supporting soil-moisture recharge and summer forage. Operations dependent on junior water rights should watch DNRC curtailment notices. Private treaty cattle buyers are active in this region through fall; current range conditions will factor into negotiated price slides.

Observed detail: 3 measurable-rain day(s) in the prior two weeks; largest single day 0.36 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.

What this means. “Percent of normal” compares actual rain to the 30-year (1991–2020) average for the same calendar dates: 100% is a typical year, below 100% is drier than usual, above is wetter. Here, the past two weeks delivered 0.70 in of rain — 104% of the 0.67 in normally expected for this window, i.e. near normal; the next two weeks are forecast at 1.11 in (144% of normal, above normal), offering a realistic chance of soil-moisture recharge.

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.

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).

Barley732
Oats78
Alfalfa hay13,73321,050
Other hay5,9684,582
Dry peas175
Canola255
Potatoes924

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.

Water & wetlands28,707

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

12,229
USDA Census
harvested irrigated cropland, 2022
DNRC mapped
remote-sensed irrigated extent
11,078
DOR assessed
tax classification, 2026

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.

Notes: A single animal can be inspected more than once in a year if it changes hands or moves across state lines twice; destination is the buyer's state of record, which is usually but not always the final feedlot. Inspection county = where the inspection took place (often an auction yard or shipping point), not necessarily where the cattle were raised. Data covers cattle only (BE-10) and excludes horse and bison inspections.
