The Valli di Comacchio are a series of contiguous brackish lagoons situated to the south of Comacchio, close to the Adriatic coast of the Emilia-Romagna region in northern Italy.
The area, covering almost 17000 hectares within the Parco regionale del Delta del Po, is classified as a Site of Community Importance and a Special Protection Area.
The lagoon and wetland complex consists four principal basins – the Valle Lido di Magnavacca, the Valle Fossa di Porto, the Valle Campo and the Valle Fattibell – and several smaller ones; approximately ten kilometres to the north, also in the territory of Comacchio, is the Valle Bertuzzi. The lagoons were formed around the tenth century due to subsidence of the soil and silting of the coastal zone. At the time of formation, the area was flooded with fresh water from the recurrent flooding of the rivers. From the sixteenth century on, they gradually were filled with sea water resulting in the modern appearance of brackish water-filled basins.
There are fish such as bream, eels, sea bass, mullet, and sole.
