It contains a large permanent, hyper-saline lake, up to 4 metres deep, with some small islands and brackish marshes at the mouth of the rivers which flow into the lake. The delta marshes of the Segundo River are particularly extensive. During periods of exceptional flooding, the lake level rises considerably and salinity decreases.» ]]>
