Catchable-sized rainbow trout are stocked when the water cools off in late October or early November. Brown trout have also been stocked in recent years and can grow to large sizes. We are attempting to establish populations of largemouth bass, black crappie and bluegill in Baker Reservoir, though it will take a few years for the fingerling fish that we have stocked to grow up to catchable size. Remember it is illegal to introduce fish into Utah's waters.
