The waters of Lake Victoria appear mostly dark blue, with the exception of one area that is green and tan from sediments. This section is Winam Gulf, a significant extension of northeastern Lake Victoria into western Kenya.
Formerly known as Kavirondo Gulf, Nyanza Gulf, and Lake Nyanza Gulf, it is a shallow inlet and is connected to the main lake by the 3 mile wide Rusinga Channel, which is partly masked from the main body of the lake by islands.
The port of Kisumu, Kenya’s fourth largest city, stands on its northeastern shore. The gulf has an average width of 16 mi (25 km) & extends for 40 miles (64 km) from Kisumu to the channel.
