Pretty sure it's a (tropical?) water lily, not a lotus.
You're probably right about that, I probably just took a guess because the flower was sticking up over the water instead of just floating on it, which tropical water lilies can also do like lotus. Water lilies or lotus, I do love them, even the plain white common ones you see on lakes.
