(major rivers in the south, such as the Wouri and the Sanaga, are largely non-navigable; in the north, the Benue, which connects through Nigeria to the Niger River, is navigable in the rainy season only to the port of Garoua) (2010)
2,800 km (the primary navigable river is the Ubangi, which joins the River Congo; it was the traditional route for the export of products because it connected with the Congo-Ocean railway at Brazzaville; because of the warfare on both sides of the River Congo from 1997, however, routes through Cameroon became preferred by importers and exporters) (2011)
24,725 km (18,300 km navigable; the most important waterway, the River Magdalena, of which 1,488 km is navigable, is dredged regularly to ensure the safe passage of cargo vessels and container barges) (2012)
1,120 km (commercially navigable on Congo and Oubanqui rivers above Brazzaville; there are many ferries across the river to Kinshasa; the Congo south of Brazzaville-Kinshasa to the coast is not navigable because of rapids, thereby necessitating a rail connection to Pointe Noire; other rivers are used for local traffic only) (2011)
3,500 km (includes the Nile River, Lake Nasser, Alexandria-Cairo Waterway, and numerous smaller canals in Nile Delta; the Suez Canal (193.5 km including approaches) is navigable by oceangoing vessels drawing up to 17.68 m) (2011)
7,842 km (includes Saimaa Canal system of 3,577 km; southern part leased from Russia; water transport is used frequently in the summer and is widely replaced with sledges on the ice in winter; there are 187,888 lakes in Finland that cover 31,500 km) (2011)
none specifically the only significant inland waterway in the country is the part of Lake Victoria within the boundaries of Kenya; Kisumu is the main port and has ferry connections to Uganda and Tanzania (2011)
1,800 km (downstream of Koulikoro; low water levels on the River Niger cause problems in dry years; in the months before the rainy season the river is not navigable by commercial vessels) (2011)
580 km (the only waterway in operation is Lake Hovsgol) (135 km); Selenge River (270 km) and Orhon River (175 km) are navigable but carry little traffic; lakes and rivers freeze in winter, they are open from May to September) (2010)
2,220 km (navigable waterways as well as the use of the large Lake Managua and Lake Nicaragua; rivers serve only the sparsely populated eastern part of the country) (2011)
102,000 km (including 48,000 km with guaranteed depth; the 72,000 km system in European Russia links Baltic Sea, White Sea, Caspian Sea, Sea of Azov, and Black Sea) (2009)
1,292 km (there are 1,227 km of waterways on lakes and rivers for public transport and another 65 km on the Rhine River between Basel-Rheinfelden and Schaffhausen-Bodensee used for the transport of commercial goods) (2010)
(Lake Tanganyika, Lake Victoria, and Lake Nyasa (Lake Malawi) are the principal avenues of commerce with neighboring countries; the rivers are not navigable) (2011)
(there are no long navigable stretches of river in Uganda; parts of the Albert Nile that flow out of Lake Albert in the northwestern part of the country are navigable; several lakes including Lake Victoria and Lake Kyoga have substantial traffic; Lake Albert is navigable along a 200-km stretch from its northern tip to its southern shores) (2011)
41,009 km (19,312 km used for commerce; Saint Lawrence Seaway of 3,769 km, including the Saint Lawrence River of 3,058 km, is shared with Canada) (2012)
