Yes, but moving a barge, let alone the required number(assuming the oil wells would be working at all) is no small feat. And where would the barges come from anyways? They are very much needed in central Europe as well. As for Don and Volga, do they link?
The there's the whole Caspian sea, witht he Soviets still on the other side of it(and Allies in Persia). You'd need to move a whole fleet there to protect the shipping.
Assuming that Baku would somehow solve Axis oil problems is a bit silly when you know that Maikop didn't help them one bit. Any such plan would take years to be put into effect.
The total length of the Volga-Don waterway is 1045 km, with a guaranteed depth of 4 m. Estimated channel capacity of the inter basin transport system for transit between the Azov and Caspian Seas is 16.5 million tons. The average navigation period is 200 days.
Maintenance of the waterway, which can be divided into three sections ¬¬-- the Volga section, the Volga-Don canal and the Don section -- is performed by the Volga, Volga-Don and Azov-Don state waterway and shipping administrations. These federal state administrations' sphere of activity includes management of ports -- Volgograd, Astrakhan, Kalachev, Volga-Don, Liskinsk, Voronezh, Azov and Rostov.
The history of creation and operation of inland waterways and the hydro-engineering constructions built on them is connected with the development of the Russian transport network. People used convenient portages between rivers from the earliest stages of economic development.
Portage between the Volga and the Don at their closest points had been used for many centuries, making the Volga-Don route attractive for transportation.
Peter the Great started construction of the canal in 1697, for both strategic purposes and for trade with the Black Sea countries of the Middle East. More than 30 attempts to connect the Volga and the Don were made between then and 1917, but most were never implemented.
The new Soviet government discussed the construction of the Volga-Don canal back in 1918. The project was assigned a top priority status, and construction works were to be implemented in several stages.
The first part of the Volga-Don canal was the Kochetov hydro-system built in 1919 some 178 km away from the estuary of the Don River. It was built to create backwater to ensure maintenance of depths at the confluence of the Don and its first tributary, the Seversky Donets River. Its commissioning had significant economic importance for the waterways of the Don basin, as it enabled regular transportation of coal from the of Donetsk coal basin and of bread produced on the fertile irrigated land of the steppe.
Between 1949 and 1952 the following infrastructure facilities were put into operation:
1. The 101 km long Volga-Don canal with 13 canal locks, 3 pumping stations, 13 dams and dykes, 7 spillways and floodgates, 22 navigation channels, 2 bulkhead gates, 8 rail and road bridges, ferry crossings, stations, piers and a 100 km channel-side highway. This amounts to 96 hydro-engineering constructions on the channel.
2. The Tsimlyansky hydro-system in Volgodonsk, with 2 canal locks, a hydroelectric power station, an earth dam, outside irrigation system and railway and highway crossings.
3. The Don main irrigation canal, the Nizhny-Don distribution canal and the Azov distribution canal.
The canal gets its water from the Don River. Three pumping stations (with a design capacity of 45 cub. m/s each) pump Don water from the Tsimlyansky Reservoir successively to the Karpovsk, Bereslavsk, and Varvarovsk Reservoirs. This water is also used for irrigation and water supply. The pumping stations are controlled from a single control centre which is part of Marinovsk hydro-system. The pumping stations are currently being refitted. Hydraulic units with an enhanced capacity of 20 cub. m/s instead of the original 15 cub. m/s are being installed at the Karpovsk and Varvarovsk pumping stations. Units of the original capacity are installed at the Marinovsk station, but their number will be increased from 3 to 4, with a total capacity of 60 cub. m/s.
The Volga-Don canal connects all the seas of European Russia in a single system.
