Fluid Generation in World

I need the code to generate lakes using worldgenlakes

You need to change this code:

    public void generateSurface(World world, Random random, int chunkX, int chunkZ) {
        for (int i = 0; i < 10; i++) {
            int x = chunkX + random.nextInt(16);
            int y = random.nextInt(54) + 21;
            int z = chunkZ + random.nextInt(16);
            (new WorldGenMinable(block.getDefaultState(), 16)).generate(world, random, new BlockPos(x, y, z));
        }
    }

I know exactly what need to replace: worldgenminable with worldgenlakes, but this is not enough
