Summary	0011622: Brook generated in Ocean biome with Z-level issue
Description	On a 6x6 embark with a Woodland biome next to an Ocean biome which happened to have a "receded tide line" I noticed the Ocean biome had generated with a brook that flowed back towards the land. Since there was a 3 Z-level difference between the floor of the Ocean biome and the Woodland, the brook was on a raised sand cliff. The bottom two levels were solid sand and the top level was a sand lip bordering the brook. Due to the "source fingers" of the brook spreading out into the Ocean biome, the water immediately cascaded off onto the sand, causing a large waterfall effect over 2 Z-levels. I would not expect brooks to generate at all in an Ocean biome and certainly not with the 3 Z-level difference.
Steps To Reproduce	Search for an embark with a River that is on the edge of an Ocean biome where the Z-levels are relatively flat.

I cannot show the pre-embark tile on the world embark map since it now shows my settlement. There is a second brook just to the east which also generates in the Ocean biome.
