prefetch, your pond is up high for Utah. I've lived in Logan, Salt Lake City, and Kamas. These places were not nearly 8000 feet above sea level, despite the state's license plate moniker of "Life Elevated".
Where is your place? Utah has some rather beautiful high country.
You have what I'd call a cool water pond. You may find it more suitable for fish that prefer cooler water. Yellow Perch YP come to mind. Any of the trouts could do well, possible better than bass and bluegills.
Our pond is considered cool water; YP and trout do okay; bass LMB and bluegills BG are able to prosper, partly because I don't aerate in summer so there is a warmer water refuge in the top 2 feet of the pond. Our pond fills from irrigation water drawn from a trout stream. That cold water sits on the bottom for the perch and trout; the sun heats the upper layer for the bass and sunfish. Our grass carp spend all their days at the surface.
Trout aficionados are few on this forum. Maybe you'll be able to join the ranks of us who keep trout alive year round.
