trout waters is closed to the public only phone calls... as for streams or rivers you could try trepanier creek that flows into okanagan lake it produces big bows sometimes as they spawn up there as well. lake wise you could do shannon lake they are hitting that lately and having good success with larger rainbows 2lb plus sometimes even the odd 5+lb comes out of there, other mountain lakes are still frozen prob as the weather is still happening up top.
As for gear, fly gear (leeches, boatman, spratley etc) all produce well. small lyman plugs, weegee spoons, dick nite spoons etc.
