Through Joseph Stalin and First five-year plan (Soviet Union)

The canal was constructed by forced labor of gulag inmates. Beginning and ending with a labor force of 126,000, between 12,000 and 25,000 laborers died according to official records, while journalist Anne Applebaum's estimate is 25,000 deaths.

The canal runs 227 km (141 mi), partially along several canalized rivers and Lake Vygozero. As of 2008, it carries only light traffic of between ten to forty boats per day. Its economic advantages are limited by its minimal depth of 3.5 m (11.5 ft), inadequate for most seagoing vessels. This depth typically corresponds to river craft with deadweight cargo up to 600 tonnes, while useful seagoing vessels of 2,000–3,000 dwt typically have drafts of 4.5–6 m (15–20 ft). The canal was originally proposed to be 5.4 m (17.7 ft) deep; however, the cost and time constraints of Stalin's first five-year plan forced the much shallower draught.

Waterway

The total length of the waterway is 227 km (141 mi), of which 48 km (30 mi) are man-made. The current flows north from Lake Onega to the White Sea, and all navigation marks are set according to it. Once in Lake Onega, ships can exit the southwest shore through the Svir River (and its two locks) to reach Lake Ladoga and then proceed down the Neva River to Saint Petersburg and the Baltic Sea. Alternatively, from Lake Onega river ships can sail eastward into the Volga–Baltic Waterway.

Route

The canal begins near Povenets settlement in Povenets bay of Lake Onega. After Povenets there are seven locks close together, forming the "Stairs of Povenets". These locks are the southern slope of the canal. The canal summit pound at 103 m elevation is 22 km (14 mi) long between locks 7 & 8. The northern slope has twelve locks numbered 8–19. The route of the northern slope runs through five large lakes; Lake Matkozero between locks 8 & 9, Lake Vygozero between locks 9 & 10, Lake Palagorka between locks 10 & 11, Lake Voitskoye between locks 11 & 12 and Lake Matkozhnya between locks 13 & 14. The canal empties out into the Soroka Bay of the White Sea at Belomorsk. The settlements of Povenets, Segezha, Nadvoitsy, Sosnovets, and Belomorsk are located along the canal.

Sailing conditions

Minimum lock dimensions are 14.3 m (47 ft) wide by 135 m (443 ft) long. The navigable channel is 36 m (118 ft) wide and 3.5 m (11.5 ft) deep, with a radius of curvature of 500 m (1,640 ft). Speed is limited to 8 km/h (4.3 kn; 5.0 mph) in all artificial portions. In conditions of low visibility (less than one km) navigation is halted.

For the navigation seasons of 2008 to 2010, the canal locks were scheduled to operate from 20 May to 15–30 October, giving 148–163 navigation days per year.
