Moist dunes valley panorama. Dune lake in the inland dunes under a blue, white clouded sky at Castricum, the Netherlands - panorama. The white Cumulus humilis clouds reflect in the silent water of the little lake. A dune lake appears when there is a surplus of rainwater, that can not sink in the ground because of an impermeable ground layer. Or when the dune valley is lower than the groundwater level. Dune lakes contain fresh water. Photo's made in the North Holland Dunes Reserve at Castricum, near parkingplace Diederik, the Netherlands,
