As Calgary is normally a few weeks ahead of Edmonton in the season and being that it is the beginning of June, my guess would be Poplar fuzz (a.k.a a symbol for the Walleye bite is on big time). I believe it’s the way Poplar's pollinate themselves.
That crap get’s on the water and it gunk’s up every line. The way I found to best help the situation is to loop on a small bead 3-4 ft up from your lure and the Poplar fuzz will accumulated on the bead and not around the end of your line and on the lure. Works great when trolling.
But it’s the Bow! Could be arse wipe too!
FYI, loose the spinning gear and get yourself a fly fishing set-up. You’ll thank me later.
