It was a pleasant day at Hicks today. A variety of species can be caught close to shore in 10' of water right now (newly stocked catchable rainbow trout, native rainbow trout, cutthroat trout and kokanee). We encountered all four species today, so not a bad option.
Manning is pretty so another good option suggested by clarki. I've been told rainbow trout are plentiful but I never caught one at Lightning Lake last year lol, but I think that was more timing (mid summer) than the location.
Shea Lake in the Kane Valley is around one hour drive from Chilliwack and it gets my vote too. Lots of feisty rainbow trout in it. Average size is 14", but bigger fish are also around. This time of the year is really quiet up there.
