Snowpack & Moisture Detail

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

Liberty County has no significant mountain snowpack within its boundaries — water supply depends almost entirely on spring precipitation and limited flows in the Cottonwood Creek and Sage Creek drainages that feed south toward the Marias River. The county is among the most precipitation-limited in Montana, averaging under 12 inches annually.

Basin Index: Cottonwood Creek and Sage Creek tributary flows into the Marias River system represent the county’s thin surface water baseline. Drought Monitor (valid 2026-09-08): Worst class D1 (moderate) over 29% of the county. Coverage at or worse than each class: D0 100%, D1 29%, D2 0%, D3 0%, D4 0%.

Two-Week Rainfall

Observed (prior 14 days) and forecast (next 14 days) · Liberty County · as of 2026-09-17

Observed detail: 5 measurable-rain day(s) in the prior two weeks; largest single day 0.32 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

Liberty County lies between the Milk River watershed to the north and the Marias River system to the south, with most of the county draining via intermittent streams toward the Marias. Chester sits near the county’s center on the gentle divide between these two major systems.

Surface water rights in Liberty County are sparse and predominantly stock water appropriations from the late 1800s to early 1900s on Cottonwood Creek, Sage Creek, and their tributaries. Most streams are intermittent by July in normal years and dry in drought years, making surface rights of limited practical value after early summer. Groundwater wells — many drilled to 200–400 feet depth — are the operational backbone for livestock water county-wide. There is no Bureau of Reclamation project and no significant reservoir storage within the county. Water rights litigation risk is low simply because there is so little surface water to contest; the real management challenge is well maintenance and drought-year hauling costs.

Federal Grazing Leases

BLM and U.S. Forest Service permitted grazing on public-land allotments · Liberty 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 Liberty 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 915,192 acres · land in farms 913,606 acres (100% 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 Liberty County.

Cattle production

Liberty County is dryland grain-and-cattle country — most operations run a spring wheat or winter wheat rotation alongside a modest cow herd of 50–200 head. The county’s small size (1,430 square miles) and sparse population mean the cattle sector is less dominant than in neighboring counties. Cow-calf is the primary enterprise with calves sold in fall through Chester or Havre auctions. No USFS grazing allotments exist in Liberty County — all grazing is on private and state lease ground.

Hay & winter feed

Dryland native grass and crested wheatgrass hay dominates; there is minimal irrigated hay ground in the county. Most producers cut once in late June or July with tonnage entirely weather-dependent. Liberty County regularly runs short on local hay in drought years and producers rely on purchased alfalfa trucked from Cascade or Toole counties. Locking in hay early — ideally by June — is standard practice for operations with more than 100 cows.

Logistics · sale barns & trucking

Chester (population ~800) has a small local sale facility used for occasional ring sales but most cattle move to Havre (55 miles east on US-2) or Shelby (45 miles west on US-2) for major auction events. US-2 is the only significant paved highway and is the primary truck route. The Canadian border is 30 miles north; Sweetgrass/Coutts is the nearest crossing at I-15 through Toole County. Remote location and limited local services mean fuel and tire stops should be planned before leaving Chester on long hauls.
