Waterway Conservation
Protecting and preserving our waterways is essential for future generations. Here's how you can help.
Why Conservation Matters
America's waterways face numerous threats including pollution, habitat destruction, invasive species, and climate change. Protecting these resources ensures clean drinking water, healthy ecosystems, and continued economic benefits.
Over 40% of rivers and lakes are too polluted for fishing or swimming
Wetlands are disappearing at a rate of 60,000 acres per year
Freshwater species populations have declined by 83% since 1970
How You Can Help
