There are a number of settlements near the river, such as Lukinovo (Лукиново), Bachai (Бачай), Zakharova (Захарова), Timoshino (Тимошино), Butyrina (Бутырина), Kaidakan (Кайдакан), Chichek (Чичек), Kachen (Качень), Znamenka (Знаменка), and Nizhnyaya Sloboda (Нижняя Слобода), mostly in Zhigalovsky District. Ust-Ilga is located by the Lena River at the confluence with the Ilga.[3] In the summer tourists visit the Ilga mainly for rafting.[1]

Course

The Ilga is a left tributary of the Lena. It has its sources in the middle of the Lena-Angara Plateau, about 150 km (93 mi) to the north of Irkutsk. It flows in a roughly northern direction across the highland area as a mountain river among large boulders within a fairly straight channel. In its middle reaches it enters a wide floodplain where it forms meanders. Shortly before its confluence the Ilga bends and turns east. Finally the Ilga meets the left bank of the Lena by Ust-Ilga village 3,773 kilometres (2,344 mi) from its mouth.[3][1][4]

The largest tributaries of the Ilga are the Ivda (Ilda) and Kichei from the right and the Typta and Tilik from the left. The river freezes between October and May. Permafrost is prevalent in the river basin.[1]

Flora and fauna

The vegetation of the Ilga river basin is characterized by dense mountain taiga, with spruce, fir and Siberian pine.

The main fish species in the river are dace, lenok, whitefish, taimen, chebak, grayling, pike, Arctic char, minnow and perch.[1]
