Confirm the current BC freshwater fishing regulations (Region 4 – Kootenay) before you fish; this water is part of the Kootenay River system.

It flows into kootenay river within the St. Mary River watershed (St. Mary River → Kootenay River). It runs stream order 6 (well down the network, toward river scale; the scale runs from 1 for a headwater trickle to 6+ for a river) and roughly 81 km. brook trout, rainbow trout, Westslope (Yellowstone) Cutthroat Trout, recorded here in provincial fish-inventory data (59 records). Named tributaries: doctor creek, lavington creek, middle findlay creek, alton creek, Granite Creek, Deer Creek, frying pan creek, periwinkle creek, clear creek, allen creek, valentine creek.

As a small stream, a tributary of Kootenay River, Findlay Creek fishes the way creeks of its size do: short drifts with a buoyant attractor dry over a light dropper, working the pocket water and the heads of pools. Match the fly box to the season and confirm against a current local report.

Access for Findlay Creek, meaning the roads in, put-ins and any walk-in or seasonal limits, is worth confirming locally before you commit a day. The drainage map shows how the water sits in its valley.
