Salish Mountains

Drought severity in Lincoln County improved sharply in late September, with moderate drought (D1) or worse dropping from 63.39% of the county in early September to 3.38% the week of September 22-28. The shift reflects seasonal relief as autumn weather moderated fire conditions across Montana.

The Salish Mountains ecosystem sits primarily on Kootenai and Flathead National Forests (GAP 3 status) and state trust lands (GAP 3), along with scattered conservation easements in GAP 2 status such as Lost Trail Conservation Area and Lost Trail National Wildlife Refuge. These forests are managed for multiple use and open to extraction, not managed for biodiversity as a primary mandate.

Lincoln County received 0.9 inches of precipitation in September 2026, 0.9 inches below the 1901-2000 normal of 1.9 inches, ranking it the 29th driest September in a 131-year record. This reflects a seasonal drying pattern that has continued across the county through early fall, leaving conditions drier than the long-term average.

Hand Creek SNOTEL reports water-year precipitation at 120% of the September 29 median, with 33 inches accumulated to date versus the 27.4 inch median. Above-normal precipitation entering autumn positions the headwaters favorably for spring 2027 streamflow, as winter snowpack accumulation follows from this base.

A western tiger swallowtail was recorded near Libby, Montana on September 20. This swallowtail species is typically active through the fall in western North America's riparian areas and woodlands.

A mountain lion was observed near Marion, Montana on September 21. Though a native predator with a broad range, this sighting documents the species' presence in coniferous forest habitat typical of the northern Rockies.
