This month's challenge is to create a map that is at least partially submerged under water. How well you address this will be judged by voters.

It could be anything from Atlantis to a partially flooded building but it must show some portion as being submerged beneath water.

This challenge will close on the 28th or shortly thereafter since it is a short month and we need all the days we can get.

Remember to include your ### WIP tag information so your entry is included on the thumbnails of the competition (see the rules thread or visit the archived challenges to see how this is done).

Have fun and keep dry if you can.
