Yes once there used to be landlocks planted but it was many years ago I have doubts that any remain, yes there are rainbows and cutts. the state stocks the lake every year but its mostly a put and take fishery but with the depth and excellent shoreline there easily could be some holdovers of good size there. I would suggest taking a look at the state stocking reports going back a few years see what has been put in there and then decide if you want to spend the time learning the lake which will most likely take some investment on your part to enjoy real success. There are a couple of year round lakes in that area that at times fish well one is pretty tough its deep also and has received plants of mostly trips. for the last few years, the other is easier and has a split season changing from selective to bait, check the regs. you'll find them.
