Catkins well advanced before leaves put in an appearance. Could have been planted originally and spreading along water's edge.

It is a declared pest plant. I helped remove some from the other side of the lake a few years ago. Is there any plan to contain it?

Not specifically that I know of, I have looked for it below scrivener Dam but not for a while so I will try and get back there soon.

It is listed as a plant prohibited for sale only. https://www.legislation.act.gov.au/View/di/2015-59/current/PDF/2015-59.PDF The City Services Lakes Ranger does control at some areas on the Lake when there is a threat to wetlands. An example is near the old Westbourne Woods. There use to be dense thickets there. If you come across thickets that are starting impact on native vegetation - definitely map the polygons Mike, on the Not-treated weeds ArcGIS Collector app map. This will bring its attention to the Lakes Ranger, and she can assess the priority in her works program. There was an old management plan for the Lake - that recommended removal of all the black alder - this would need initiative funding as it is a big job.
