Birch Creek is a 6.1-mile-long (9.8 km)[2] northeastward-flowing stream originating on the western slope of the Bear River Range in Franklin County, Idaho, United States.

Its mouth is at the confluence with Mink Creek about 12 miles (19 km) northwest of Preston, Idaho.

In addition to increased drought, Bonneville cutthroat are threatened by introduced non-native trout species through predation, competition, and hybridization.

[3] The instream and riparian degradation of Birch Creek is associated with decades of heavy cattle grazing pressure, removal of beaver (Castor canadensis), and encroachment of pinyon and juniper forests.

Channel incision has lowered the water table and reduced floodplain connectivity, which has further adversely affected the condition of the riparian areas which is critical habitat for a variety of aquatic and riparian obligate species particularly greater sage-grouse (Centrocercus urophasianus).
