Green Algal Bloom on River Ribble

Green Algae by the River Ribble Settle - it beautifully matches the green grass and opening leaves - but - is it
  • -a natural sign of spring growth?
  • -a response to air pollution in some way?
  • -a mark of how much the water level in the river has been falling regularly over the past days - So the volume of water is 1/20th or less what it was two weeks ago - and the alga is left stranded?

Opposite Settle hydro - 5 May

See how the green borders the water of the river. Ribble above Langcliffe below the old Paper Mill
