Pistoia
Pistoia is crossed by several rivers, although no one is large and is characterized by a regime of torrentizio. The largest of these rivers is the Ombrone Pistoiese that can tap to the west of the city. In its course, arrived in the district of San Biagio, Ombrone Pistoiese presents clear waters and clean, capable of hosting even valuable fish species such as sea trout, vairone and scazzone. Its scope during the summer seasons undergoes a huge reduction caused mainly by indiscriminate levies for agricultural purposes, risking to stay dry for several months. Among other waterways are present torrent Brana, which washes the walls of the city north-east.
