I use 12 pound mono... still the snags stay as snags no matter what, I walk downstream give a pull, upstream, give a pull, still nothing. Someone told me that if you get the line tight, then pull it by the reel (the tip should flex and bend down more), then let go, the hook should jump and release, it works surprisingly! But it doesn't work every time.
On the way in to cook park, there are several large ponds connected, then looks like a slow stream flowing into them. Kind of looks like Bass water... Kinda doubt it though... I'll take pics of them next time and post them. PM if you want pics of my carp =) kinda huge!
