Is there no circulation of the water (moat?)? The water should be circulated and aerated to prevent algal growth, which can harbor diseases.
 
Maguari
All the moats in this area were the same. Very unusual to see. Helped the 'hidden barrier' effect, of course...

This looks more like duck weed (Lemna sp.) I don't know if the animals can access the water but if so they will end up with a film of green leaves over them selves.
A surface skimmer of the type used in Koi/garden ponds would help keep the surface area clear, though t may also suck any native waterlife in as well, fish fry or tadpoles spring to mind.

What algal growth? The moat is covered in duckweed.

Yes, it's (mostly) duckweed. Extreme case though!

Ok. Thanks for confirming that it is duckweed, I wasn't sure so I said algae. They should keep ducks or fish to eat the duckweed, but that would also mean necessary aeration of water to keep fish.

I'm confused why you all think its important to remove/control native vegetation? Accumulation of duckweed similar to what is in the photo is common in slow-moving bodies of water throughout the southeastern US.

Fishkeeper's instinct, I think! If you've ever kept an aquarium or fish pond then anything making the water look green is instinctively the enemy! :D

I did wonder about the labelled-but-absent Pink-backed Pelicans and whether being coated in duckweed was the reason for the absence...

...or maybe the bongos that might have considered the pelicans "toys". I highly doubt duckweed would be much of a bother to pelicans.
