Deçan Bistrica

River in Kosovo

Lumbardhi i Deçanit, or Deçan Bistrica or Dečani Bistrica (; ), is a river in Kosovo. It is a long right tributary of the White Drin River, passing the western part of Kosovo.

The river's name, Lumbardh, literally translates to White River in Albanian. The adjective, i Deçanit, differentiates it from the other Lumbardh tributaries of the White Drin in the Dukagjini area. The other name, Bistrica, means "clearwater" in Serbian. Like the official name, the adjective Dečanska, "of Dečani", is added to distinguish it from other Bistrica rivers in the Dukagjini region: Peja's Lumbardh ("of Peć"), Prizren's Lumbardh ("of Prizren"), Baba Loc's Lumbardh ("of Baba Loc/Kožnjar"), Lloqan's Lumbardh ("of Loćane"), etc.

Lumbardhi i Deçanit river originates from the southern slopes of the Bogiçevica mountain, a part of the massive Bjeshkët e Nemuna mountain system. The river flows north of the Gjeravica peak, the highest in Kosovo (2,656 m), initially under the name of Lumi Shqiptar, and receives many streams from the Bogiçevica, Micinat, Strečoka and Kopranik mountains. The river turns southeast on the northern slopes of the Kopranik and Strečoka mountains, where it carved the deep gorge of Deçan (Gryka e Deçanit). The upper part of the gorge is the glacial trough of the ancient Deçan glacier on the Bjeshkët e Nemuna, or Accursed Mountains.

As the river flows out of the gorge it reaches the medieval monastery of Visoki Dečani, which is on UNESCO's World Heritage List. The river continues eastward, in the very densely populated area next to the small town of Deçan and the villages of Isniq, Beleg, Jabllanicë, Këpuz, Kotradiq, Kralan, Lluka e Epërme, Lumbardh, Nepolë, Papiq and Vranoc, before it empties into the White Drin. In the upper course, the waters of the river are used for the Kožnjar hydroelectrical power plant (6.5 MW). In the lower parts its waters are, to some extent, used for irrigation. The Lumbardhi i Deçanit belongs to the Adriatic Sea drainage basin, drains itself an area of , and it is not navigable.
