Polbrock Bridge
The Camel River matures through various phases. Rock grinding down to pebbles and then coarse sand, silt coming off the agricultural hinterland.
This part of the river is deeper in places and more sophisiticated. The surrounding woodland gradually gives way to an area of wetland, not quite marsh but something close to it. The river meets different influences and matures gradually
The wetland is perpetuated by floods at times. At Polbrock but noticeably at Pendavey Bridge the river level can be swelled by big tides pushing up from the open sea at Padstow
