No Jamila, this is at the far end of the canal near Whatstandwell. The main navigable stretch between the point you mention is fine and still well looked after.

Hi all,
Looks like <"Lemna minor">, not technically an algae, but a higher plant.

Looking at the <"growth and leaf colour">, if they are using the <"Duckweed Index"> they need to reduce the nutrients a bit and change some more water.

Funny you should mention that.. this is a disused mill pond at the back of our house, the water that fills it is the run off from several farmed fields, evidently packed with nutrients going off the duckweed index.
