Lake Manych-Gudilo

Lake Manych-Gudilo, Priyutnensky District, Republic of Kalmykia, Southern Federal District, Russia

Lake Manych-Gudilo, a significant saline water body in Kalmykia, Russia, extends its reach into Rostov Oblast and Stavropol Krai. Positioned at coordinates 46°20′09″N 42°47′58″E, this expansive lake covers an area of approximately 344 square kilometers. Despite its vast expanse, it is relatively shallow, with an average depth of just 0.6 meters and a maximum depth of 2.2 meters.

Geographical Significance

This lake holds a critical position as the source of the West Manych River. This river meanders northwest, passing through several reservoirs before merging with the lower Don River, shortly before it meets the Sea of Azov.

Climate and Biodiversity

The region surrounding Lake Manych-Gudilo experiences a wide range of temperatures throughout the year, with winter lows reaching down to -30 °C (-22 °F) and summer highs soaring up to 40 °C (104 °F). This climate variation has given rise to a rich biodiversity in the area, particularly notable for its avian population.

Ecological Importance

The lake’s vicinity includes the Chernye Zemli Biosphere Reserve, a testament to the ecological significance of the region. This reserve plays a vital role in preserving a variety of bird species and maintaining the ecological balance of the area.

Potential Future Changes

An interesting geological aspect of Lake Manych-Gudilo involves its potential future in the context of global sea-level rise. Studies suggest that a global sea level increase of approximately 25 meters (80 feet) could lead to the formation of a narrow channel between the Sea of Azov and the Caspian Sea. This channel would straddle the lake and could result in the submergence of the Caspian Depression area.
