Minnesota National Lakes Assessment Project: Aquatic Macrophytes in Minnesota Lakes

The United States Environmental Protection Agency (EPA) has a responsibility to assess the health of the nation's water resources. One of the methods for assessment is statistically-based surveys. The survey of the nation's lakes, conducted in 2007, is one of a series of water surveys being conducted by states, tribes, the EPA, and other partners. In addition to lakes, partners will also study coastal waters, wadable streams, rivers, and wetlands in a revolving sequence. The purpose of these surveys is to generate statistically-valid and environmentally relevant reports on the condition of the nation's water resources of streams, lakes, wetlands and estuaries at nationwide and regional scales.
