LakeCat data are available for download (use Microsoft Edge)
EPA's Office of Research and Development (ORD) has developed the Lake-Catchment (LakeCat) Dataset, an extensive collection of landscape metrics for about 378 thousand lakes and associated catchments within the conterminous U.S. LakeCat includes both natural and human-related landscape features. The data are summarized both for individual lake catchments and for cumulative upslope watersheds.
LakeCat was developed to parallel the StreamCat Dataset and to support the National Lakes Assessment (NLA). The data will also be useful to states that are conducting similar assessments. LakeCat data, which are available to the public for download, provide an important tool to understand and characterize the Nation’s lakes.
