It flows into columbia river within the Lower Arrow Lake watershed (Lower Arrow Lake → Columbia River). It runs stream order 3 (mid-range in the network; the scale runs from 1 for a headwater trickle to 6+ for a river) and roughly 7 km. brook trout, bull trout, mountain whitefish, northern pike, rainbow trout, walleye, white sturgeon, recorded here in provincial fish-inventory data (111 records). The fish-passage model expects Brown Trout, burbot, Cutthroat Trout, kokanee, Lake Trout, Lake Whitefish, Smallmouth Bass here too, since the reach is reachable with no barrier between, though there is no direct record yet.

As a small stream, a tributary of Columbia River, Sullivan 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. Match the fly box to the season and confirm against a current local report.

Access for Sullivan 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.
