The source of the Moraca river lies at the base of the mount Lola, and runs into Skadarsko Jezero close to the town of Podgorica. It is 100 km long. Together with the Tara river it is one of the rare European rivers whose waters are unpolluted and drinkable almost all the way from the source to its mouth.
Zeta is a river near Nikšić, under the Planinica hill flows eastwards for 86 km (53 mi) until it confluences into the Morača River just north of Podgorica. One theory is that the name “Zeta” derives from an early root meaning “harvest” or “grain” (modern words žetva and žito).
River Cijevna (Cem, Cemni in Albanian) is left tributary to Morača river. The spring of Cijevna is located west of Trojan mt. (2,183 m) in the Prokletije mountain range, and the river flows from there in SW direction as Cem Selcit through Malësi e Madhe region in Northern Albania. After Cijevna reaches the border of Montenegro, and finally enters Montenegro south of Suka Mizdrakut (1,144 m) mountain, it forms a canyon with high and steep sides.
The Piva is a river in Montenegro and Bosnia and Herzegovina, shorter headwater of the Drina river, which it forms with the Tara river on the border with Bosnia and Herzegovina. The Piva springs from the Sinjac spring on Golija mountain, near the Piva Monastery (also called Vrelo Pive; Well of Piva). Before the artificial Lake Piva (Pivsko Jezero) was formed, the water from the well rushed into the river Komarnica thus creating the Piva river for the next 34 km.
In the surroundings of wonderful plunging into the abysses, bellow the steep slopes sometimes more of a thousand meters deep, cutting forcibly its very way between the Bjelasnica, Sinjajevina, Ljubisnje and Durmitor mountains, flows one of the most beautiful Montenegro rivers, the Tara river. Like a cut furrow between mountain peaks, the clear-water mountain river flows, and its very waters, from time to time make for wonderful landscapes in tame and fertile valleys in which acres, orchards, forests and meadows may be seen, with its flocks of sheep and goats, very often together with game graze.
The Bojana or Buna, is a 41 km long river in Albania and Montenegro which flows into the Adriatic Sea. An outflow of the Skadarsko Jezero (Lake Skadar), measured from the source of the lake’s longest tributary, the Morača, the Morača-Lake Skadar- Bojana system is 183 km long.
