It should evaporate given long enough time (and it's not raining) or you simply will have to use the terrain tool to cover it up by raising the land a bit.

Was there a water source below (or near) that island before you raised it? That would cause the problem you described. If so it will continue to "bleed" water forever.

It happened to me recently, I think it can be removed in the map editor but I did not try. Raising the land more did not help me as it became way too high and still leaked all over.

So I raised the land around the edges of it it which created a lake. I did not want the lake there so I went back in saves and found the water source and stayed away from it.

Yea I did this by accident, normally I woulda terra form over smaller lakes etc. no problem but this one had what appears to infinite water source and just kept spewing water no matter how much dirt I put there. Its now a lake that I have like 6 water pumps on to keep it from flooding...which it was doing.

Lake in the bottem left corner. Its at maximum depth as well lol.

Oh in that case you need to delete the water spawn point which you can do with the mod "Water Features".
