Hill County, Montana

Overview

Hill County is a major Hi-Line agricultural county anchored by Havre, one of the principal commercial centers of north-central Montana and home to Montana State University Northern. The county stretches from the Canadian border south to the Bear Paw Mountains and contains most of the Rocky Boy Indian Reservation (Chippewa-Cree Tribe). Agriculture is dominated by large-scale dryland wheat and barley operations on the Hi-Line benchlands, supplemented by cow-calf ranching in the Bear Paw foothills and along the Milk River bottomlands. The BNSF Hi-Line rail corridor and US-2 run east-west through Havre, making it a major grain-handling and commercial hub.

Weather & Moisture

Hill County has one NRCS SNOTEL station — Rocky Boy — at about 4,730 feet in the Bear Paw Mountains, which provides the county’s only direct snowpack measurement. Water supply is a mix of Milk River mainstem flows (fed by the St. Mary Canal diversion in Glacier County plus Bear Paw Mountain runoff), Big Sandy Creek (draining the Bear Paws south of Havre), and direct precipitation driving dryland wheat productivity. The USGS gauge at Big Sandy Creek near Havre captures the Bear Paw drainage; Milk River gauges at and near Havre track the mainstem.

Water Rights & Land Ownership

Water rights in Hill County are anchored by the Milk River (subject to the complex compact involving Montana, the Bureau of Reclamation’s St. Mary Canal diversion from Glacier County, the Fort Belknap Reservation’s senior Winters Doctrine rights downstream, and the Rocky Boy Reservation’s tribal rights in the Bear Paws), plus Big Sandy Creek, Sage Creek, and other Bear Paw drainages. The Rocky Boy Reservation holds tribal water rights through the Chippewa-Cree Settlement. Montana DNRC WRQS is the primary research tool.

Hay & Winter Feed

Irrigated alfalfa and grass hay along the Milk River bottomlands support the county’s cow-calf operations. Dryland hay production is variable given the semi-arid climate. Most of Hill County’s agricultural acreage is in small-grain crops, not hay.

Cattle Production

Cow-calf operations concentrated in the Bear Paw foothills (on and adjacent to the Rocky Boy Reservation) and along the Milk River benchlands form the county’s cattle base. Fall-weaned calves typically move through Havre-area order buyers or ship east to Glasgow / Malta (in Valley and Phillips counties).

County Logistics

Havre sits at the intersection of US-2 (the Hi-Line) and US-87. It’s approximately 110 miles east of Shelby (I-15 access) and 130 miles west of Glasgow. US-87 runs south through the Bear Paw Mountains to Great Falls (approximately 115 miles). BNSF rail through Havre supports the county’s substantial grain operations. Trucking to Billings runs approximately 4 hours via US-87.
