The Nzoia River is a 160-mile (257 km) long Kenyan river, rising from Mount Elgon. It flows south and then west, eventually flowing into Lake Victoria near the town of Busia. The river is important to Western Kenya, flowing through a region estimated to be populated by over 1.5 million people. Its waters provide irrigation all year round, while the annual floods around the lowland area of Budalangi deposit sediment that contributes to the area's good agricultural production. Around the industrial region centred at Webuye, the river absorbs a lot of effluent from the paper and sugar factories in the area. The river has a number of spectacular waterfalls, and is thought to possess a good hydroelectricity generation potential. Mount Elgon is an extinct volcano on the border of Uganda and Kenya. ...
