I can’t speak personally for Deep lake. But you will find perch in the Chain lakes. Katepwa, Mission, Echo and Pasqua do have fair numbers of perch, walleye and pike in them. You can find lake depth maps online for these lakes. I have had luck at Katepwa for perch and big pike fishing in depths from 10 - 27 fow. There should be plenty of posts on this forum with spots for most of these lakes.
