The only "other" lake in that area where you might get bigger than planter size trout is Big
Twin. If you C&R flyfish Little Twin is open for C&R only too amd has some medium sized trout....check your regs for the rules on both lakes. All the other lakes near there have planter size only pretty much except moccasin which is pay to fish.
Don't completely write off Perrygin Lake. It has some huge carryovers for those that know how and where besides the crop of recent planters.
The clue for the carryovers is when they get big enuff they start feeding on CRAYFISH in that lake....that should give ya a hint what to use. Try a fishfinder for where they move around. Probably suspended over deeper water this late in the year and may not bite at all untill fall.
