Generally winters here tend to be mild, which makes for some nicer fishing conditions usually starting in February. The weather we have been having for the last few weeks is quite exceptional, with warmer average temperatures and light amounts of rain in the Valley, the Rivers around whistler have been fishing quite well for the last few weeks and should fish great Into the upcoming 2010 Olympic games.
Sea-Run Bulltrout, Rainbow, Cutthroat and the odd Steelhead are around right now with plenty of char being taken in the 24"+ size bracket.
Bring your 7wt switch or small Spey if you can, or a single hander can work too. Olive Zonkers and Muddlers work quite well during that time, as do flesh patterns, Alevin, Glo-bugs and good ol ESL's. No Need to switch up flies for Steelhead either as they are consistently taken on swung Egg suckers and olive Zonkers fishing for Trout!
