No fish records turn up for Paulding Creek in the provincial stream data covering the Horsethief Creek watershed, and no guide, report or online log names it specifically. That is not proof of an empty creek, small steep headwater tributaries are routinely under-surveyed, but it does mean Paulding Creek is honestly a regulation-and-access check rather than a confirmed fishery. If it does hold coldwater fish, the character of the wider Horsethief system points toward small-stream basics:
mayflies,
caddisflies and
stoneflies imitations with summer
terrestrials, but that is a hypothesis carried over from the surrounding watershed, not a record from Paulding Creek itself. If you do scout it, a small-stream box of
Adams,
Elk Hair Caddis and
Stimulator on top, with a
Hare's Ear or
Prince Nymph underneath, covers the reasonable bases.
