If your luck was poor for Coho, you might want to recocider Chill Lake. Kids like fast action. I don't know when you want to take them, but if time permits you would be better off waiting intill the water warm up. Cold water = sluggish fish. Also Dad you might consider a compromise and try a more kid freindly species. The Crappies in Wonnock Lake for one. I know of some great Kid lakes in the Cariboo where your kids could have a good chance at 30 to 50 fish days, fishing for pansize rainbow on the worm, but trout producers of that quality here are rare unless you want to pay. So take the kid to Wonnock any where from May through Sep. Bring home everybodies limit of Crappie (you will need that many to make a good meal out of them) and the kids will be telling everyone what a master angler Dad is. My two cents as a Father, Mentor, and Angling Instructor.
