Upper Arrow is defined by reservoir level. Know whether you are in lake, river or drawdown-area rule language, and plan access around launches that still work at the current pool.

Drawdown-area rules include trout/char quota, bull trout size/harvest limits, single barbless hook and stream-closure exemptions. Tributaries have bull trout C&R. Confirm per water.

The shoreline you see in May may not be the shoreline you launch from later. Drawdown defines habitat, access and regulation wording. Fishable water is often boat water: deep edges, creek mouths, ferry-reach structure and kokanee movement.

Bull trout, rainbows and kokanee carry the angling story. In the broader Arrow system, kokanee provide the food base for large predatory trout. Burbot and whitefish are part of the cold-water fish community, but the fly or trolling conversation usually comes back to kokanee-fed trout.

Use the same basic Arrow reservoir logic: baitfish flies and bucktails when fish are up, deep presentations when they are not, and streamers around legal creek-mouth opportunities. For pure fly casting, expectations should stay modest until local reports say fish are shallow.

AAA Guided Tours, Reel Adventures, Mountain Valley-style reservoir guides and Nakusp/Revelstoke operators may cover Upper Arrow or nearby Columbia water. Confirm method, launch, pool level and whether the trip is fly-focused.
