On a lovely autumn morning, 8 of us cleared the Floating Pennywort from Swan Island cut. A plank on a ladder made a useful bridge.
After a couple of hours work, it was satisfyingly clear of pennywort.
We organised this working party at short notice, because we discovered this hidden reservoir last weekend… If not dealt with, it would soon break up in the frosts and spread fragments to re- infest the rest of the river.
