Nzoia

The Nzoia River is a Kenyan river that runs for 257 kilometers and originates in the Cherangany hills. It runs through Kapsara, Springer, and Moi's Bridge before crossing into Kakamega County. It flows south, then west, eventually emptying into Lake Victoria near Port Victoria. The river has a discharge of around 118 m3/s, or 3,721 million cubic meters per year.

The river is vital to Western Kenya, as it flows through a region with a population of more than 3.5 million people. Its waters supply irrigation all year, and the annual floods that occur near Budalang'i's lowland area deposit sediment that aids in the area's good agricultural production. The river receives a lot of effluent from the paper and sugar factories in the area around the industrial region of Webuye.

The river contains several impressive waterfalls and is regarded to have high hydroelectricity generation potential. Unfortunately, the river's bottom end, which is flat and swampy, floods every year. In the Budalangi flood plains, this results in a constant humanitarian disaster.
