The Mbagathi River, which runs perennially through the entire Nairobi National Park (NNP), has apparently been dammed, stopping the flow of water that sustains both flora and fauna in the park and beyond, several conservationists have observed.

The river appears to have been dammed to make it possible for a petrol pipeline under construction to run through the eastern part of NNP. It is not clear whether the Kenya Wildlife Service (KWS) and the Water Resources Management Authority approved the damming of the river.

An Environmental Impact Assessment (EIA) would also be necessary to gauge the effects of damming on downstream communities and ecology. It remains unclear whether an EIA was carried out in the case of damming the Mbagathi River.

Photographs by Brian Finch show ongoing pipeline construction inside NNP and the effects of damming on the river.
