Welcome Haffee , last year I did stock some rainbow trout , they were a lot of fun catching in the winter when most everything was " taking it easy ", the trout were on fire anytime we wanted to wet a line , My pond is used pretty often for swimming in the summer months but IMO if your swimming the water will be above the thresh hold of anything a trout can live in anyway , its just my own opinion as we stocked 200 trout NOVEMBER 17 2022 and caught almost all of them , we noticed MAY 17 2023 ( exactly 6 months to the day ) our first " floater " as the water was reaching 70 something degree's and even though for this old guy that's to cold for me to swim in I am sure some KID might have made a day of it , my thought is that i am just not sure how much swimming a family would do with water temps in the mid to upper 60's if in fact your pond sustains that beautiful cold water . here in Missouri we open up the beach and pond Memorial day and we DO have the little NIPPERS like everyone talks about , its possible no one talks about swimming up there as the water stays cold enough to be prohibitive to fun swimming but if that is the case the Trout should LOVE that cold water
