The southwestern part of U. Gishu is drained by the Sosiani and Kipkarren rivers. River Sosiani rises close to the crest of the Elgeyo‘ Escarpment and flows westward through Eldoret onto the Selby Falls. The River eventually joins up with River Kipkarren close to its western tip. Plans are underway to found nature, an amusement park along River Sosiani on a 4kms stretch nearby Eldoret town earmarked to be its inaugural Urban Green Park. It will feature viewing areas, birding pads, a heritage village, and an amphitheatre.
