The last day that ODFW stocked Waverly Lake was on Thursday, March 11th. But, I drive by there a LOT and it doesn't seem to get too much pressure. So, there still should be some trout in there.
It also has bass, bluegill and crappie and maybe some cats. But, I don't know where to target them. Maybe someone else will add to this thread.
BTW, welcome to my home state and to OFF!
