The Mat (definiteAlbanianform: Mati) is a river in northern Albania. Its source is near Martanesh, in Dibër County. It flows west towards the municipality of Mat, which takes its name from the river, and northwest through the towns of Klos and Burrel. About 10 km (6 mi) downstream from Burrel, it flows into a large reservoir (Liqeni i Ulzës – "Lake Ulëz"). After passing through a hydroelectric dam, it flows through another, smaller reservoir (Liqeni i Shkopetit – "Lake Shkopet") and forms a narrow gorge through the mountain range that separates Mat District from the coastal plains. It enters the plains between Milot and Zejmen.
