The Tarn River runs in a roughly westerly direction, from its source at an altitude of 1,550 m on Mont Lozère in the Cévennes mountains (part of the Massif Central), through the deep gorges and canyons of the Gorges du Tarn (that cuts through the Causse du Larzac), to Moissac in Tarn-et-Garonne, where it joins the Garonne River 4 km (2.5 miles) downstream the center of town. The Tarn River is famous for its brutal floodings, which are the most dangerous in Europe along with the Danube River. The famous flooding of March 1930 saw the Tarn rise more than 17 meters (56 ft) above its normal level in Montauban in just 24 hours, with a discharge of 7,000 m3/s (average discharge of Rhine River is 2,200 m3/s; average discharge of Nile River during the traditional annual flooding before the building of the Aswan Dam was 8,500 m3/s; average discharge of the Mississippi River is 16,200 m3/ s). One third of the Tarn-et-Garonne département was flooded, about 300 people died, thousands of houses were destroyed, the low districts of Montauban were destroyed, the town of Moissac was almost entirely destroyed.
