Description
To remedy the presence of a watershed in the lagoon, the Taglio Nuovo (“New Cut”) was dug connecting the basin of Grado with that of Porto Buso, while a channel on the left leads to the Banco d'Orio. Extreme caution is needed in following this channel because of the shallow waters and oyster beds. Exit to sea is not advisable because of the submerged bar that extends in the area where the channel leads into the sea. On the other hand it is an area rich in birds, especially waders, which can be observed feeding at low tide on the very extensive flats, as they concentrate in large dormitories on the sandbanks remaining at high tide. To the west of the channel leading to the sea is the Noghera valle, the largest in the region, while to the east there is the Morgo valle.
