National Lakes Assessment

The National Lakes Assessment (NLA) is a comprehensive survey conducted by the U.S. Environmental Protection Agency to evaluate the health of lakes across the country. It involves collecting water samples and data on factors like pollutants, nutrients, and aquatic life to assess water quality. The goal is to understand how lakes are changing over time, identify environmental threats, and inform policies to protect these vital freshwater resources. The NLA helps ensure lakes remain safe for drinking, recreation, and supporting ecosystems.
