Local fish-inventory data has no recorded observations on Stark Creek itself, positive or negative. The wider Toby Creek family holds
bull trout throughout the mainstem,
westslope cutthroat concentrated in Jumbo Creek's middle and lower reaches, and Dolly Varden scattered through the smaller tributaries, so a similar mix is plausible here. Expect the same small mountain-stream forage as the rest of the family:
stoneflies,
caddisflies and summer
terrestrials, with
sculpin and
baitfish possible in any lower, better-connected water. Until a survey confirms a population, treat Stark Creek as an unconfirmed water: carry the same small mountain-stream box as Toby and Jumbo, but don't plan a trip around it.
If you do explore it, match the rest of the Toby family: a
Stimulator on top, an
Elk Hair Caddis or
Adams through the afternoon, and a
Hare's Ear or
Prince Nymph to probe the deeper pockets and small stonefly nymphs beneath the faster water. Small, dark streamer patterns cover the outside chance of a char.
