Kinbrook River
From Vanathul Wiki
About
The Kinbrook River is the primary outlet of the water melting along the night in the summer season. It is also fed by rainfall from surrounding mountains and wetlands.
In truth the volume of this river makes it more like a long lake that slowly makes its way out to the sea. In the summer it exceeds its bounds, flooding large areas in Camor, gradually rising and falling as the melting ice feeds the flow.
The flood planes of Norsett drain mostly into the Stockchester(the inland mendarian lake?), or back into the Kinbrook river once the levels lowers again.
