Something green has been sprayed on banks of creek. Weed killer?? Photos included. pH high. Could this be connected? Rained between the photos of the spray evidence on Friday and our testing on Sunday.
Banks of creek near test site cleared again. Much less riparian vegetation than past years. Significant flow through pipe under dam wall so more of lake water now flowing through creek test site.
Water ribbons budding. Cockatoos in tree hollow recently had chicks.
Oval next to creek fenced off and dug up for upgrading.
