Year of Water

This year, 2022, is the 50th anniversary of the Clean Water Act. Because 95% of Avalonia’s lands feature water, we invite you to join in exploring the impact of water on all of us and better appreciate Avalonia’s role in protecting this valuable resource.

Avalonia protects

Water, water everywhere. Sometimes that’s good and sometimes… not so much!

Southeastern Connecticut’s lands are rich with deep aquifers that supply residents with some of the best drinking water in the country. Our water is filtered by abundant forests dotted with ponds and wetlands and fed by countless streams and brooks. Water suppliers (and your well!) rely on protected land to keep our water resources safe, clean, and less likely to need expensive processing. Avalonia’s 4,500+ acres play an important role in getting that job done.

Water can also be a threat. Rising sea levels, storm flooding, pollution and disappearing wetlands threaten our homes, communities, biodiversity, and environment. Avalonia’s shoreline properties buffer rising seas far better than a sea wall. Our preserves provide shelter to fragile brooks and wetlands teaming with wildlife. We are getting that job done, too.
