Overview
The Zeya Reservoir (Russian: Зейское водохранилище) is located in the upper course of the Zeya, below the southern foothills of the Toko-Stanovik, a subrange of the Stanovoy, to the north of the junction of the Tukuringra and Dzhagdy ranges.[2] The reservoir is kept at a regulated depth of 93 metres (305 ft). A narrow, 40-kilometre-long (25 mi) valley separates the dam water body from the vast surface of the reservoir. The Baikal-Amur Mainline railway runs along the north shore, where a 1,100-metre-long (3,600 ft) bridge has been constructed.
Settlements on the shore of Zeya Dam include Beregovoy, Khvoyny, Gorny, Verknezeysk, Bomnak and Snezhnogorsk.
