The City of Cork is having a demonstration of how swamps are produced in Fitzgerald’s Park in Cork this week.

Mind you, I don’t think that was their intention, but with the fountain out of commission there is no oxygenation of the pond, and hence the algae are killing the pond and creating a wonderful swamp.
It’s a shame to see the pond so overrun with algae.
I don’t know if the blog helped, but they responded to email today that the fountain is under repair, and that the algae will be removed as part of the regular maintenance.
