Course

The Arga-Sala is a left tributary of the Olenyok. Its sources are in the northeastern slopes of the Bukochan Range, Central Siberian Plateau, in the Evenkiysky District of Krasnoyarsk Krai. The river is formed at the confluence of the long Left Arga-Sala and long Right Arga-Sala. The Arga-Sala flows roughly eastwards with rapids and riffles in numerous stretches. It flows then across a floodplain with small lakes, changing direction with southeastward and northeastward bends, but still within a generally eastward trend. Finally it joins the left bank of the Olenyok river upstream of Olenyok village, Olenyoksky District, one of the few inhabited localities of the area. The Arga-Sala is frozen between October and May.

Its main tributaries are the long Kengeede, the long Kyuyonelekeen and the long Kukusunda from the left, as well as the long Kyuyonelikeen from the right.

The river flows north of the Arctic Circle across a lightly-wooded taiga zone. The most common trees are larches.
Taimen, lenok, whitefish, grayling and pike are the main fish species found in the waters of the Arga-Sala.
