(Russian: Новосиби́рское водохрани́лище), informally called the
Ob Sea (Обско́е мо́ре), is the largest artificial lake in
Novosibirsk Oblast and Altai Krai created by a dam on the Ob
River near Novosibirsk. The dam, built in 1956, is for
generating hydroelectric power. The reservoir is 160 km long and
up to 20 km wide. The power of hydroelectric power is 400 MW.
During the summer, it is one of the most popular destinations
for Novosibirsk residents with many yachts and boats dotting the
surface of the lake, and the beaches teeming with people. Most
villages are situated on the western coast. The Karakan Pine
Forest is situated on the eastern coast of the reservoir.
