El Riu Tana amb uns 1000 km, és el riu més llarg de Kenya, i dona nom al Tana River County.^[1] la seva conca fa prop de. 100.000 km².^[2] Rls seus afluents inclouen el Thika, Ragati River des de Mt.Kenya i d'altres de menors que només flueixen en l'estació humida. ElTana neix a les muntanyes Aberdare a l'oest de Nyeri. IniciLment discorre cap a l'est i després cap al sud al llarg del Mont Kenya. Hi ha una sèrie de preses hidroelèctriques que proporcionen els dos terços de l'energia elèctrica necessària per Kenya.^[3]^[4] en.^[5]^[6]^[7]^[8]

Després de les preseses el riu flueix cap al nord El cabal anual és de 5.000 milions de metres cúbics amb grans variacions segons els anys pluviomètrics.^[9]^[10] Hi ha regadius importants.
