This is not possible AFAIK. You can use a little trick that works since TTO, though: Bomb a water tile with the bulldozer, pause the game (or bomb it while paused if you have BuildWhilePaused on), then place a piece of track or a depot on the tile. That doesn't work with stations, though, they will be removed shortly afterwards. Another trick, which is only feasible if you don't have to worry about your finances nor town ratings in the area, is to raise the water tiles one level, thus eliminating the lake, and lowering the land afterwards down to sea level (the area mustn't be adjacent to any water tile, or otherwise the water will slowly flood the tiles again).
