An Earthwatch research project investigating the health of global freshwater ecosystems on a scale never seen before.

We ask that all FreshWater Watchers ensure that they are following the latest advice in their region regarding self-isolation, social distancing and movement. If local restrictions mean that you are not able to take part in FreshWater Watch activities, please postpone them for as long as necessary – your safety and wellbeing are our priority.
Following the updated government advice for English citizens, on Monday 11th May, we are pleased to announce that the suspension of FreshWater Watch has been lifted in England. As long as you comply with government advice on self-isolation, social distancing and movement, in addition to FreshWater Watch safety guidance, you can resume FreshWater Watch monitoring activities if you wish to and feel able to do so safely. In Scotland, Wales and Northern Ireland, all non-essential FreshWater Watch activities remain suspended until further notice. Please keep abreast of the latest government advice as this is changing frequently.

A 300% rise in phosphates has led to an increase in algal blooms which can damage human health.
