I was fishing in Palmer back in the 90’s. I know rivers & streams are all the rage, but we included a stocked lake in the edge of town. We used a boat there, may of been free, possibly a rental. One could catch all the rainbows you wanted, 12”+ length. We were mainly using rooster-tail & similar spinners. We only kept 4 that were badly hooked, had some salmon to eat.

Check with a bait or outdoor shop, they could point you in the right direction. Our timeframe was late July.
