Description
The easternmost part of the Grado lagoon has been mostly drained and the Primero basin was consequently also reduced. Currently, the mouth feeds the area of canals around the Valle Panera as far as the sanctuary of Barbano and Belvedere. The lagoon basins are separated by zones of watershed where there is greater sedimentation and the channels tend to silt up. In the area between Primero and Lignano, the watersheds are more evident near Barbana, and in the artificial channels called “tagio novo” (“new cut”) and the link of Sant’Andrea. These channels connect the different basins and are straight and bordered by tidal flats where the excavated material has been dumped. In the area behind the mouth, immediately upstream of the Monfalcone-Grado road bridge, there is an old settlement of casoni called “Rotta Primero”. The contrast between the adjacent golf course and the spontaneous conglomeration of fishermen’s huts is very marked.
