Guys like Nate who are seeing rainbow trout hold over in some of the ponds and small lakes they manage could most likely see HSB grow to rather large sizes in those same lakes as they obviously have thermal and DO refuges for large HSB if they can also support trout. As long as those ponds and lakes have abundant food for the HSB to feed on while taking refuge, I suspect they could grow quite large!

Bruce, you've grown some rather large HSB over the years, any data on temps and DO in your ponds?
