Flame...I have treated waters with temps over 90 degrees and just after using prop wash to melt 3 inch thick ice cover (~35)...Both turned out well...I guess the "best" time of year is when YOU are ready!
Snipe, in the other Alum thread, you said after ice out, your pond was clear...Your question is answered! Your turbidity issue is a mechanical issue. Unless you know no bullhead or common carp are in the pond, it is wind wave action and rip rap need to be deeper on the prevailing wind side of the pond. If aerated, a diffuser may be tipped over or does not have a large enough base to prevent bottom scouring
