This is a complex ephemeral system of broad, shallow, vegetated channels that flows south out of Angola after good rains, meandering through the sandy soils and mostly ending in large pans.
The largest system, the Cuvelai, reaches the vast grassland of the Ombuga, where the channels form a permanent serpentine series of saline lakes, including Lake Oponono. After good rains the Ekuma, Omulonga Gwashigambo and Nipele river channels reaches the Etosha Pan. The southern portion of Oshana region is an extensive savannah plain stretching as far as the Etosha Pan.
