That's a typical indication of a heron having been in your pool.

Strange that there has been no evidence of a predator, like
damaged foliage, pond plants etc all left intact, the heron must
be very stealthy to leave to trace.



Herons have low cunning believe me. We have a regular visitor. He
often flies over doing a recci I reckon. Comes early in the
morning. Fishes until disturbed in our wildlife pond.
My other pond is concrete box over a meter deep. Never goes near that
