Mara River - The Mara's Effects

The Mara's Effects

The river is a vital source to grazing animals nearby. Although during the dry season it may often appear shallow, it may swell to up to twice its normal size after heavy rainfall. This can create rapids in the river, which may lead to shortage of food for predators that cannot cross the river to hunt.

Between the 1950s and 2006, the seasonal water quantities in the Mara have changed significantly in the sense that are now higher peaks and lows in the river flow. These dynamics are associated with changes in land use in the catchments area: decreasing vegetation covers are causing a faster run-off of rainwater. Near the river mouth in Tanzania, the rapidly fluctuating water levels in Lake Victoria of the previous century have further added to discharge difficulties of the Mara River. Consequently, floods have become more common and large parts of the Tanzanian Mara wetlands have become more permanent instead of temporary wetlands.
