Giant Blockage at the Stream

This is pile of polystyrene is as tall as us standing up.

The blockage is made up of lots of twigs and leaves in the middle of the stream!

Last week there was a blockage of twigs and leaves, it could impact on the macro-invertebrates because without flowing water it would die because it has no oxygen. We tried with a giant stick and try and loosen it but it didn't do much help. It was also blocked by a pile of polystyrene. H.L
