[FlyTheory]

So everyone this season will be my second time fishing spray lakes. I did last year and hooked up about 8 times in 45' of water off a sunken island. I got out there and lost my medium action rod, so I was fishing with my backup UL rod... and lost every one I hooked because I didn't have the power. It seemed to be all lakers though...

Im going back when the ice freezes up over Christmas. How come people fish deep on this lake? For the veterans of spray lake, why do you go so deep? Do you look for structure? Ive watched the videos on youtube, and they say to "go deep" but no one has an explanation for why.
Obviously I dont want spots I'm just looking for some tips on what part of the lake to hit up next. I was thinking the far south end...

Thanks in advance!
