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 Kootenay Lake watershed (Kootenay Lake → Kootenay River). It runs stream order 4 (mid-range in the network; the scale runs from 1 for a headwater trickle to 6+ for a river) and roughly 10 km. kokanee, rainbow trout, Westslope (Yellowstone) Cutthroat Trout, recorded here in provincial fish-inventory data (26 records).

For an angler judging whether the fishing is worth the drive, the stocking record is the fishing report. Boulder Creek is a kokanee program, a mix of forage stocking and a put-and-take sport fishery: 6 recorded releases totalling 2,266,460 fish (Kokanee), last stocked 2010-10-22.

Stocking appears to have wound down after 2010. Confirm whether it is still topped up or now fishes as a residual, wild population. The chart below shows the full release history.

As a small stream, a tributary of Kootenay River, Boulder 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. The stocking record below is the truest read on what you will catch.

Access for Boulder 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.
