Hopefully Angler 1,Ditch Jigger,Bob G,Steve from Mass and JP see this post these gentlemen are true canal rats ! They should be able to help out.Skilled fisherman.
You need to give more info. on how you fish ie:eels ,Jigs,chunks,plugs
imho-Be patient,you do not learn the canal in a couple of days or nights. It takes time. Most of all keep your line wet. Good luck and have fun.
