LakeCat Dataset
URL: https://www.epa.gov/national-aquatic-resource-surveys/lakecat-dataset
LakeCat currently contains over 300 metrics that include local catchment (Cat), watershed (Ws), and special metrics. See Geospatial Framework and Terms in the ReadMe for definitions of the terms ‘catchment’ and ‘watershed’ as used with the LakeCat Dataset. An additional metric, inStreamCat, indicates whether the variable was pulled from the StreamCat Dataset or calculated with a geospatial framework that was developed for LakeCat.
These metrics are available for 378,088 lakes and their associated catchments across the conterminous US. LakeCat metrics represent both natural (e.g., soils and geology) and anthropogenic (e.g, urban areas and agriculture) landscape information.
