Lake Zeway is also a freshwater lake, and it has five islands of which one is said to have housed the Ark of the Covenant during 16 century in order to protect it from an Islamic warrior named Gragn as nickname. The lake is fed by the Meki and Katar Rivers, but does not always have an outflow; sometimes it overflows into Lake Abiata.
