Gonna be difficult, at best, to find "frozen water" in Georgia. The intent I believe is clear.
As for floating/wading down a stream and taking deer on the land, that is another subject. Probably legal, but the regulations better be checked first to be sure...wherever you are. There are some curves in the regs that MUST be complied with or you are illegal. Period.
No since taking any deer and later finding that it was taken illegally. Makes the whole experience one that would best be avoided when what you really want is to tell everyone. Braggin' rights are great when everything is done right. No sense skirting the regs.
