The Alzou is a short river in the Lot département, southern France, a right tributary of the Ouysse. It is 31.4 km (19.5 mi) long.[1] It flows through the towns Gramat and Rocamadour, and joins the Ouysse, itself a left tributary of the Dordogne, downstream of Rocamadour. The valleys of both the Alzou and the Ouysse are deep limestone canyons.
