Two-Week Rainfall

Observed (prior 14 days) and forecast (next 14 days) · Glacier County · as of 2026-08-02

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

Glacier County drains eastward into the Milk River basin, with the Two Medicine River and Cut Bank Creek as the primary arteries. Both streams confluence with the Milk River downstream near Shelby and Havre.

The Two Medicine and Cut Bank Creek systems support irrigation for native hay meadows and stock water for cow-calf operations across the county’s bench country. Senior water rights in this basin date to the 1890s homestead era, with many held by the Blackfeet Nation under senior federal reserved rights that take priority in low-flow years. The Milk River compact between Montana and Canada adds a transboundary dimension that can restrict diversions in dry years. Over-allocation is a concern in drought years, particularly on Cut Bank Creek below the Blackfeet Reservation boundary. Secondary water sources include stock ponds filled by spring runoff and shallow wells in alluvial valleys. Ranchers near Browning and Cut Bank typically hold older priority dates tied to original homestead filings.

Federal Grazing Leases

BLM and U.S. Forest Service permitted grazing on public-land allotments · Glacier 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 Glacier 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 1,916,897 acres · land in farms 1,115,475 acres (58% 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 Glacier County.

Cattle production

Glacier County supports a mix of cow-calf operations on the Blackfeet Reservation and private ranch land east of the Front. Calves typically wean in October and move to feed yards in Nebraska and Colorado. USFS and BLM allotments on the Front provide summer grazing from late June through September for operators based near Browning and East Glacier. Ranch units tend to run 100–500 head, with tribal operations averaging larger. Yearling stocker programs are less common here than in the Milk River corridor to the east.

Hay & winter feed

Native grass hay and irrigated grass hay from Two Medicine River bottom ground form the primary winter feed base. Cutting typically begins in early July with a single cutting common in drier years. Alfalfa is limited by late frost risk near Browning. The 2025 season outlook depends on Two Medicine snowpack and June precipitation. [draft — verify against current conditions]

Logistics · sale barns & trucking

Cut Bank (US-2) is the primary shipping point, with Shelby (I-15 / US-2 junction) offering interstate access for trucking to Billings or Missoula feeders. The nearest major sale barn is in Havre, roughly 90 miles east on US-2. Fall run shipping typically peaks in October before early winter closes mountain passes. Rail access at Shelby provides an alternative for large consignments moving to Midwest feed yards.
