It's Sebek
Crocodilopolis, city of the water dragon
"Twenty five miles south of Memphis the Djedhis constructed a huge manmade lake called Lake Moeris and founded a city of the water dragon or crocodile upon its shores. Later the Greeks of the Hellenic Empire designated this city as Crocodilopolis, "the place of the crocodile-dragon."
The patron deity of Crocodilopolis was Sebek, a manifestation of the Primal Dragon when it initially emerged from the Cosmic Sea. Sebek, the crocodile god of time and cycles, was intimately associated with an ancient Egyptian cycle of 60 days, a Serpent Cycle based upon the crocodile's 60 teeth. Sebek's celestial constellation was part of the Big Dipper and served as an important indicator of the annual cycles of nature.
At Moeris the dragon god Sebek was worshipped as the numerous live crocodiles which inhabited the depths of the holy lake and occasionally sunbathed upon its sandy shores. According to the historian Strabo, the priests of Sebek treated the crocodiles as pets and affectionately served them a daily ration of bread, meat, and wine. When they died, their bodies were mummified and interred in a nearby mausoleum."
