Not the day for it
River high but settled. Not much stacked in your favour today. Worth an hour if you are nearby, not worth the special trip.

About this water

The upper Yukon around Whitehorse is accessible northern fly water — a big, cold, lake-fed river with Arctic grayling, lake trout and pike. It once carried one of the longest Chinook salmon migrations on earth, but those kings are now severely depressed and closed to fishing; we carry the salmon as present-only and direct anglers to the grayling, lakers and pike instead. Clear lake-fed reaches make for pleasant, accessible northern fishing.

Under the surface

The upper Yukon around Whitehorse and the Southern Lakes is a big, cold, lake-fed river holding Arctic grayling, lake trout and northern pike, with Chinook (king) salmon historically running far up the system. Clear in its lake-fed reaches and sizeable, it offers accessible northern fly fishing for grayling and lakers — though the once-great Chinook run is now severely depressed and closed to fishing.
