I have spotted a chunk shaped lake water in desert biome after created a new world, not sure if it's generation bug?

Please provide the seed and the coordinates.

I have updated with new screenshot, Thanks for letting me know.

Cannot confirm at that location. Please see attached screenshot.

Wow that is odd.. Never mind then I guess. You can close it anyway.
