The Simiyu River Watershed in Tanzania covers an area of 13,972 km². The average annual rainfall in the watershed ranges from 700 mm–1,000 mm. The Simiyu River is ephemeral and its waters discharge into Lake Victoria. Primary land uses in the watershed include grassland, woodland, and cultivated land, The primary uses for Simiyu River waters are agriculture, fishing, and livestock production. Primary threats to water resources in the watershed include: water fluxes due to land use/land cover change; pollutants in water courses; and, high rates of soil erosion.(Mulungu and Munishi, 2007; Rwetabula et al., 2007)

This dataset comprises precipitation and temperature data as available and shareable for Simiyu River Watershed, Tanzania.
