Caspian Depression (, Caspian Lowland) is a low-lying flatland region encompassing the northern part of the Caspian Sea, the largest enclosed body of water on Earth.. It is part of the wider Aral-Caspian Depression around the Aral and Caspian seas. Other translations include Pricaspian/Peri-Caspian Depression/Lowland.
The lowest point of the depression is 28m or 92 feet below sea level. The depression lies at the southern end of the Ryn Desert, and is in both Kazakhstan and Russia. Most of the Russian Republic of Kalmykia lies in the Caspian Depression. The Volga River and the Ural River flow into the Caspian Sea through this region. The deltas of the Ural and Volga Rivers are extensive wetlands.
The North Caspian depression is part of the continental or semi-arid desert biome. The area receives 30 centimeters (12 in) of rain or less per year, on average, and less than 10% of the region is irrigated. Karagiye, the lowest point in Kazakhstan, is in the depression, at 132 meter (from [www.wikipedia.org](http://www.wikipedia.org/wiki/Caspian_Depression).
