There's a chance the pool might remind you of the chamber full of whispering pools back in the Cavern... But the main difference here is that, if you get very close and listen very carefully, you can understand the words rising from the water.

Hello! Can you hear me? Hello! Is someone there? Hello! Hello! Hello!

If one were to make themselves known to this voice, intentionally or otherwise, it will make a request:

I can help you if you help me! A favor for a favor? Just scatter my flowers at the Oasis, and I can help you find something you've lost.

Let us know what is done with the flowers, if anything, and if there would be any follow-up questions for the voice in the water.
