Thanks for your interest in FreshWater Watch! Thousands of people around the world are helping us to investigate the health of freshwater ecosystems on a scale never seen before.

Everyone is welcome but please note that FreshWater Watch is best undertaken as a team - be it through your work, local school or voluntary organisation.
