This took about fifteen minutes of work, after I had the materials. It's a 64x64x64 cube of water smack in the middle of the map, and might take as much as a day to remove without hacking it out of the map data (depends on how you feel about placing 4096 blocks by hand while trying to stay afloat in downward current). What you need to bring about your own Noahic deluge: Two buckets of water, and lots of dirt. These are materials that could be gathered inside of ten minutes, assuming there's any iron to be found at all on the map. How to do it: Pillar up to the very top of the map with your dirt. Once there, dig back down one level so that you have room to place all the water.Carefully start building diagonally out from the edge of the pillar, alternating from the north to the east or whichever, until you've built four blocks out or so.Place the first water block on top of the pillar. Place the second water block on the block diagonally adjacent to the pillar.Dig away all the dirt that's under water to let it all fall down.Grab a bucketfull of water from the nearest spring (it will automatically regenerate)Build out a little bit more diagonally so that you have room to back upPlace a water block diagonally adjacent to the mass of water you're growning (it will run down the sides)Repeat steps 4-7 until somebody notices and bans you/tries to kill you.From Minecraft Forums, I tried it and filled up a bit area on my Survival World ______ Also, here is my texture pack.
