Hey Buckshot98,
I was one of the guys fishing beside you Saturday and the lone guy out there Sunday until the two old timers showed up. Should have come over and we could have shared some info.
Regarding the other lakes you mentioned I have done some research on them as I was interested in trying them also. Church lake is a hike into only and full of lake trout but very small 10-12" no big fish here. Grouse and Watershed can be accessed via a logging prior to Squeers. I never went but had a friend who use to go there. There is no boat launch but you can drag a boat down a hill by quad or hand. He claims the fishing is good in June. Fish are the same size as Squeers 1.5-2.5 pounds on average.
