Creek runs and floods rip everything away, not just the trollies and bikes, the sheets of corrugated iron, the branches, the dead animals and birds, but also the litter. If it’s been a while between runs the litter builds up till the creekbed is carpeted with crap. About 90% (best scientific guesstimate) is drink bottles. It doesn’t sound much from this description, and the pictures don’t do it justice, but some mornings the sheer quantity stops me in my tracks.
They wash up and down with the tide, for weeks at a time in summer (when there are fewer runs and floods), gathering around the litter boom by the TAFE then pushing upstream before settling into a plastic tideline.
I hate it.
