Forsyth Creek carries its own Classified Water listing (Region 4-23): no fishing from Connor Lake downstream 3 km. The remainder follows the Elk River tributaries Classified Water rules (4-2/4-23): trout and char daily quota 1, none under 30 cm, bait banned June 15 to Aug 31, bull trout catch-and-release, the whole system closed Sep 1 to Oct 31, and Class II when and where open, tributaries included. Non-resident anglers need the Elk River classified licence. Confirm the current synopsis before you fish.

upper Elk River trend only; Forsyth Creek itself is ungauged

Forsyth Creek is an official Kootenay Land District water, its mouth fixed at 50.224722, -114.961389 by federal geographical-names records. It drops out of the Height of the Rockies into the upper elk river valley, and BC Parks maps a Connor Lakes/Forsyth Creek trail through the park's wilderness terrain, cutthroat fishing included, but with no potable water, difficult navigation and industrial-road hazards on the approach. A 2018 Elk Valley cumulative-effects assessment placed Forsyth Creek in the low-hazard group for rainbow-trout hybridization based on 2016 sampling, while still flagging roads, stream crossings, riparian disturbance and temperature as valley-wide stressors worth watching.

Fish-inventory records for the creek total 50 direct observations: 26 westslope cutthroat trout, 8 bull trout, 8 brook trout, 3 Dolly Varden, 3 unidentified fish and 2 mountain whitefish. That is a real cutthroat-and-char signal for a small upper-valley tributary, closer in character to a cold, technical headwater creek than a roadside dry-fly stream.

Direct hatch samples have not been taken on Forsyth Creek itself, but it sits inside the same Fernie/Elk hatch window as the mainstem: golden stoneflies near the opener, mayflies, caddisflies, midges, summer terrestrials, and fry or sculpin behind the char. Fish attractors and terrestrials where the water is open and legal: a Stimulator, Chubby Chernobyl, Royal Wulff, Adams or Elk Hair Caddis on top, with Pat's Rubber Legs, Prince Nymph, Hare's Ear, Pheasant Tail or Copper John underneath. Where bull trout rules allow it and away from redds, a sparse Woolly Bugger or Muddler Minnow covers the char.

There is no maintained trailhead or parking area confirmed for Forsyth Creek. BC Parks maps a Connor Lakes/Forsyth Creek trail through the surrounding wilderness, but flags no potable water, difficult navigation and industrial-road hazards on the approach, so this is not a casual roadside stop. No guide publishes Forsyth-specific trip reports; Elk River Guiding Company and Kootenay Fly Shop & Guiding cover the wider Elk Valley and its tributaries, useful for regional context, but that is not the same as a report from this creek.
