No Bennison Creek-specific exception appears in the Region 4 synopsis. As a Duncan Lake watershed tributary it falls under Duncan Lake's tributaries (4-27): bull trout release, covering the Upper Duncan River and its tributaries, plus the regional stream defaults: closed Apr 1 to Jun 14, trout and char catch-and-release Nov 1 to Mar 31, and a single barbless hook required year-round. Confirm the current synopsis before fishing.

Bennison Creek runs stream order 4 (a mid-size tributary, roughly in the middle of a network scale that runs from 1 for a headwater trickle up to 6 or more for a full river), stretching roughly 8 km through Upper Duncan terrain. Channel geometry has not been measured for this creek, but at that order and length it reads as a modest, likely narrow feeder stream rather than anything approaching mainstem scale. No fish have been directly recorded here in provincial inventory data.

With zero direct fish records, no guide coverage and no fishing reports, Bennison Creek is unproven water. The wider Duncan Lake watershed model carries an inferred sportfish signal spanning westslope cutthroat trout, bull trout, rainbow trout, kokanee, mountain whitefish and burbot, but that is a watershed-level hypothesis, not a catch record on Bennison Creek itself. A neighbouring water in the same batch, cockle creek, does carry confirmed kokanee and slimy sculpin observations, which shows the watershed can hold fish, but only fieldwork on Bennison Creek itself would confirm a population here.

Duncan Reservoir monitoring adds a caution worth carrying into any plan: most reservoir tributaries outside the Upper Duncan River mainstem provide limited spawning and rearing habitat because of steep gradients and limited usable habitat, so a small watershed like this is more likely to be marginal fish habitat than a proven fishery.

If it does hold fish, reservoir food context from Duncan monitoring is the working guide: zooplankton dominate kokanee diet, with mysid shrimp also taken, kokanee spawning peaks late September into early October, and bull trout spawning runs broadly early September to mid-October. A cold-tributary hatch calendar of stoneflies, caddisflies, mayflies, midges and terrestrials is the likely small-stream complement, with sculpin or fry where habitat allows. A box built for that spread would run an elk hair caddis, adams, royal wulff or stimulator on top, a prince nymph, hares ear nymph or pheasant tail nymph underneath, and a small woolly bugger for sculpin or fry.

No confirmed public access point, road condition or trailhead has surfaced for Bennison Creek. It sits in remote Upper Duncan reservoir country alongside recorded neighbours like Hall Creek and cockle creek; treat overland travel and any stream-side access as unconfirmed until checked on the ground.
