Its not really worst its just pure Badwater.. the strengh of the sources does not change so the river does not overflow etc.
Water sources can be positive or negative. If set to negative they suck in water up to the amount you set the source to. Same for positive you can set the strengh in the editor to 0.1 or 8 positve or -0.1 to -8 negative! That is intented. :)

but during a badtide that must be more worst ? no?
Another thing that i have not understood , the big canyon at the east was never filled (clear or bad water ) but there is no exit for water inside ???Also i have noticed after than somes water sources was the exit ? i never saw that before, is it intented?

thx for your comment Wuik. Happy to hear you had a challenge. :)
A Water source next to the Badwater source gives the player an easy way with closing the badwater to have an addition river instead of a badwater river.

Ok! i have upload this map on another site..
i have finished with a wonder...
easy for the beginning and more hard for the mid game and end game to me..
Cos there is a lot of mecanish that i have don't understood...
Managed the badtides took really a very long time to do...
put a water source near the bad water source why????
First time i have used the dev control to fired that water source
