Any good flooded maps that actually work?

Anyone know any flooded maps that work? All the ones I've came across are broken.

 

Just go in map editor and raise the water level.

 

How i can do it?

 

F11, then just click on the water, and find to movement thing, and drag it up. Just don't save the level. If you want to create a copy of the level, you can find it under the wiki.
