About this water

Above the reservoir, the Oldman is native westslope cutthroat and bull trout water — clear, cold mountain freestone running off the Livingstone Range through wild foothills country. The fishing is genuinely good in summer and autumn, but these are sensitive, recovering natives: it's catch-and-release, often bait-banned, and worth fishing lightly and gratefully. Late June once the snow clears through October.

Under the surface

Above the reservoir the Oldman is wild native-trout country — a clear, cold mountain freestone of riffles and pocket water running off the Livingstone Range, holding native westslope cutthroat and bull trout in a landscape of foothills forest and rough access roads. This is recovery water: the fish are special and sensitive, the country is big, and the fishing is as much about the place as the catch.

Wading: Swift cold water, remote access, bear country

  • Confined

Conservation note

Native westslope cutthroat (SARA Threatened — catch-and-release) and bull trout (char, zero limit, catch-and-release). This is conservation water; we never score these natives as harvest. Whirling disease present in the Oldman basin — Clean-Drain-Dry.
