Just one strange think (I don't know if it is the source of error!).  
You use a bit strange definition of lakes there - areas water. They  
are defined by bottom wall and the water level is defined by another  
line wall -outline in. See attached picture 1.

Standard way is something as you may see on picture 2. The line  
defined area is border and the wall clips the area inside the passage.

In such case you may use "adjust horizontal" for line point to make  
the water level allways horizontal. Check the extension of Rabbit  
cave in samples.
