World Water Day, held on 22 March every year since 1993, is an annual United Nations Observance focusing on the importance of freshwater.

The theme of World Water Day 2020 is water and climate change – and how the two are inextricably linked. For those of us who live, work or play on lakes, we are already seeing the impacts of climate change, from rising water temperatures, loss of winter ice cover, changes in lake stratification, increased evaporation, and more extreme weather events, including droughts and intense rainstorms. Climate change is further complicating already challenging lake protection and restoration efforts, from managing harmful algal blooms (HABs) to preventing and controlling invasive species.
