Shershni Reservoir, reservoir in Russia

Shershni Reservoir is an artificial lake on the Miass River in Chelyabinsk Oblast, Russia, created between 1963 and 1969. It stretches 18 km in length, with a maximum width of 4 km and an average depth of 4.5 m. The shoreline is mostly smooth, with hilly terrain and steep banks on the south and west, and shallow bays. The water is bordered by sandy shores and vegetation including willows, birches, and maples.

Planning for a reservoir on the Miass began in 1924, when the site was judged suitable. Construction started in 1962, water was diverted into the basin from 1965, and the reservoir and dam were completed in July 1969. Filling submerged 2,959 hectares of farmland and 300 hectares of forest, including the village of Mitrofanovka and parts of Kise li, Chernyaki and Mikhailovka.

A partly asphalted, mostly unpaved road runs around the reservoir 50 to 200 m from the water. The eastern shore, especially the northern part bordering the City Forest, is the main public recreation area; the western shore lies outside Chelyabinsk's city limits. The dam in the north carries a trafficked motorway.
