As a relative newcomer to the wetlands, I was surprised at how quickly
the main swamp dried up over the past 2 months. It was sad to see it
almost completely dry, and of course, to have the water birds leave
for other locations.
On Saturday morning (30 March 2019), I was pleasantly surprised to
find the return of a significant amount of water following just one
night of rain. With the return of the water, there were a good number
of waterbirds there, as well as a flock of a hundred or so seagulls.
As I stood there enjoying the scene, I had a number of questions run
through my head. I have expressed them below, and any answers from
those with more knowledge of the wetlands would be very gratefully
received.
How often does the swamp dry up? Is this an annual Summer event?
Is the swamp fed by a combination of groundwater and stormwater? Or
just one or the other?
Is there any control of the water inflow by the folks at the treatment
works across the road?
