Winter Holding Lies:

go a little lower and a little slower. If you fished the very heads ad fast tailouts of the pools, move toward the center of the pool and find a current break on the bottom. live minnows are tough to beat this time of year, but since we're on the fly forum I assume you're using a fly rod. Indi nymphing with small flies has always been my best fly bet this time of year. Tiny (18 or 20) apricot sucker spawn, sometimes with some flash are one of my standard flies. Black stones are also pretty standard fare this time of year.

thanks

A floating line will be fine.  I haven't seen much, if any, water in the erie tribs that require a sinking line.
 
Even in cold water I go with water clarity to determine color/size of my flies. 

Thanks guys ,you helped me too. I just don,t do well in winter with fly,s. It seems like the small sucker spawn is always tyed on. lol

transam, your weight forward line might and probaly is a floating line. if you got the box it came in the lines are designated as wf8f meaning. weight forward, 8wt, floating. if it were a sinking line it would read like, wf8I or wf8s which is weight forward, 8weight intermediate sink or S meaning sinking line. hope this helps.
