The Desert region has some of the best water features, Forest only gets cookie-cutter ponds and sinkholes
I guess this is due to the makeup of Atys, with the live organic areas absorbing the water quickly, not requiring surface drainage, (come to think about it.. the forest area boundaries are clifftops - so very high ground )
The dead ground matter in desert seems to be less absorbant, so you get the lakes at Dyron, Thesos, Offlovaks....,
And the LakeLands must be at low altitude, (lower than Prime Roots i guess ) so the run off from the rest of Atys pools there.
