Originally known as the Pole River, the lower Birkenhead's valley is part of the
Long Portage of the
Douglas Road, also known as the Pemberton Portage. The height of land on this route has been variously called
Pemberton Pass (officially), Birken Pass, Gates Pass, and (in
gold rush times) Mosquito Pass. The river is a major
salmon resource for the
Lil'wat subgroup of the
St'at'imc people, whose reserve community
Mount Currie which spans the lowland between the very lowest reaches of the
Lillooet and Birkenhead Rivers.
Owl Creek At Owl Creek, a few miles up the Birkenhead, there was one of the major missions of the
Oblate missionary organization, to which
Lil'wat people from up and down the Pemberton Valley (
Lillooet River valley above
Lillooet Lake) moved, ultimately to become the
Mount Currie community. Owl Creek is now a large non-native subdivision on the west side of the local highway from Mount Currie to
N'quatqua (D'Arcy). ==Gates River==
