Before the unnatural creation of Nym-Zoedine glacier, this waterway was a small stream. With the glacier, it became a wide channel flooding areas downstream. It flowed southeast through the Trog Run and then into the Cthorgo sea. In the Sathubas Waterworks Project, the aboleth created the water siphon Vector GG-4. This was built when a stream still flowed through the area. The glacial melt turning the stream into a river eventually bored a great cavity downward into the Sathubas region. This environmental change was welcomed by the area's trogs and others who had long suffered from flooding.
