Editing Manych (section)

==Canals==
Historically (prior to the construction of the dams and irrigation channels, i.e. until 1932–1940 for the West Manych, and until 1969 for the East Manych), both rivers were intermittent. During dry years, and even during the drier parts of normal years, both Manych Rivers would consist merely of a chain of small lakes or ponds with brackish or salty water. The system usually would be fully filled with fresh water only during the spring [[freshet]].<ref name=bazelyuk/>

Since the mid-20th century both Manych Rivers receive significant amounts of fresh water via a network of irrigation canals. Since 1948–1953, the West Manych has been receiving water from the [[Kuban River]] (via the [[Nevinnomyssk Canal]] and the [[Yegorlyk]], a left tributary of the West Manych) and from the [[Tsimlyansk Reservoir]] on the [[Don (river)|Don]] (via the Don Canal). Since the late 1960s, the East Manych has been receiving water from the [[Terek River]] and the [[Kuma River (Russia)|Kuma River]] via the [[Kuma–Manych Canal]] and [[Terek–Kuma Canal]]. According to A. Bazelyuk's calculations, the annual water flow in the West Manych (measured at the Vesyoly township) is 8.3 times as high as it was previous to the canal and dam constructions, while that in the East Manych (measured at the [[Chogray Reservoir|Chogray Dam]]) is 4.3 times as high as before.<ref name=bazelyuk/>

If the plans for the proposed [[Eurasia Canal]], linking the Caspian Sea with the Black Sea, are ever implemented, it will likely follow the Manych valley in its central and western section.
