The Active Delta of the River Po in Italy, South of Chioggia45.2N 12.2E
The River Po flows eastward across northern Italy to the Adriatic Sea. Here, its delta can be seen along the shores of the sea. Along the coast, northwest of the delta, is the coastal town of Chioggia in the Veneto Region, situated on a small island at the southern entrance to the Lagoon of Venice. It appears here as a white area at the top center.
The most recent part of the Po Delta projects into the Adriatic between Chioggia and Comacchio. It contains channels that actually connect to the Adriatic and on that account is called the active delta by the park authorities, as opposed to the fossil delta, which contains channels that used to but no longer connect the Po to the Adriatic.
The active delta was created in 1604 when the city of Venice diverted the main stream, the Po grande or Po di Venezia, from its channel north of Porto Viro to the south of Porto Viro in a channel then called the Taglio di Porto Viro, or “Porto Viro cut-off.”
