yes those three banks specificly, a while back there was people on boats the broke off the whole banks lines the came till about 15-20 from the bank and drove from one point to the other....
the bank wher your blue and red marks meet on the other side is a verry good place to fish from the boat, deep and rocky no grass or anything, almost the whole part of the other side of the nature reserve is unfishable from the side Private grounds) but very fishable from a boat... good luck when are you planing to go?
