Panfish can be caught year round in our area. All of the Suffolk water supply reservoirs hold good populations of crappie, bluegill, shellcracker and yellow perch. Western Branch is probably your best bet if you want white perch. Smith can be really good for crappie, but I haven't caught any other panfish of any size there. The yellow perch have probably already started to show in the rivers, but not likely in any great numbers. January, February and March are your best bets for those. Also, many of the creeks that dump into Back Bay can also hold fish year round and would be ideal for your kayak. Good luck!
