This body of water is simply called the Lake of Gesshed. Its year-round liquid surface is now less than 500 feet square, catching the flow of the Gasshadu river after irrigation ditches and urban users are done with it. In the rainy season it fills the whole basin, but the water acquires a distasteful, dusty flavor.
People sometimes scratch their head and wonder where the water goes, and go diving looking for the hidden sinkhole they can plug up and restore plentiful water to the city. The people who came over the Scarp from Dulsharna just shake their heads. "It is happening here, as it happened there," they say, and begin counting their possessions. "Pray to Mitra, for portection from the Serpent." But the locals have no idea what they are talking about.
