Andreyevskoye

Andreyevskoye belongs to the Konda lake country of western Siberia. The Konda is a 1,097-kilometre river that rises on the western edge of the West Siberian Plain and joins the Irtysh from the left. Its basin covers 72,800 square kilometres, collecting water through a broad lowland network and passing settlements and industrial sites that depend on the river’s course. The seasonal rhythm of the Konda dominates movement through this country.

Ice usually closes the river from late October until late April, while the spring and summer thaw releases a much larger flow. The average discharge measured 164 kilometres from the mouth is 231 cubic metres per second, but the recorded maximum reaches 1,220 and the minimum 36.1. These extremes reflect a flood season and a low-water season rather than a steady channel. The town of Uray and the Shaimskoye oil field lie along the river, adding later settlements and raw-material use to a landscape long organized by water, ice and marsh.

Its main tributaries include the Mulymya, Bolshoy Tap, Yukonda and Kama from the left, and the Yevra and Kuma from the right. The river’s discharge changes sharply between low water and flood.
