Summary

If anglers want to find lake trout in a particular kind of lake while this lake is partially iced in late winter, then they should fish near the surface. Why? Because:

1) Lake trout will be in the coldest water.

2) This particular kind of lake undergoes temperature changes in late winter and fall; during this time, the location of the coldest water will change.

3) In winter, the coldest water is at the top.

Notable Assumptions

The recommendation specifically speaks to anglers fishing during late winter, which is when the turnover happens. We don’t know when exactly this turnover occurs, we only know it’s sometime in late winter. So, we don’t know whether the anglers are fishing before or after the turnover. If it’s before the turnover, then yes, the coldest water will be on top. If it’s after the turnover, then the coldest water will not be on top. We need to know that the turnover hasn’t happened yet.
