The people in charge of campus call this an eyesore. Every now and then they empty it into the storm water system. (Is that legal?). Then they get a big bulldozer to scoop out all those nasty green reeds.
When we argue with them that it's worth leaving, they scratch their scalps and say, 'Don't be stupid. How can it be? It's just a drain for the surrounding area.'
I strolled down there at lunchtime. It was too hot for much to be out and about, but I saw two species of dragonfly, a damselfly, an Australasian grebe and a water hen with chicks. At other times, I've seen Pacific black ducks, white-faced herons, moorhens and coots. Yes, what an eyesore ...
... Quite unlike the weeds that they've planted in the garden beds. I'm pretty sure that half of them are banned from sale. And the other half ought to be.
