watershed = The Rotaldo, known in its upper course as the Laio, is a 40 km river (classified as a "torrente") of northern Italy, and a right-side tributary of the Po. Most of its course falls within the Province of Alessandria. The river is of modest flow, heavily reliant on rainfall, with a discharge near its mouth of 1.6 m²/s.

The river is born as the Laio near Grazzano Badoglio in the Province of Asti, close to one of the springs of the Grana del Monferrato. Its early course makes an arc through the hills of the Basso Monferrato, heading first WSW then curving gradually to WNW, receiving the waters of a number of small streams from the left and passing through the commune of Olivola and between Vignale Monferrato and Frassinello Monferrato. Near Occimiano it acquires the name "Rotaldo" and enters the Casalese plain through which it follows a sinuous course, passing through Borgo San Martino, Ticineto and Valmacca until it enters the Po at Bozzole.
