History

Between 1909 and 1911 the North Baikal Highlands were explored by Russian geologist Pavel Preobrazhensky. He surveyed the river valleys of the area, all of them tributaries of the Lena basin, including the Chechuy.

Course

The Chechuy is a right tributary of the Lena. It has its sources in the Akitkan Range of the North Baikal Highlands. It heads first northwestwards across the mountain area. Approximately in mid course, the river turns to the NNE and flows roughly in that direction until it reaches the Lena. Finally it meets the right bank of the Lena from its mouth, near Puschino, a little downstream from Zolotoy, and downstream from the mouth of the Pilyuda.

Tributaries

The largest tributaries of the Chechuy are the long Lower Rassokha and the long Middle Rassokha that join it from the right. The river freezes yearly between October and May.
