    "description": "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.",

    "description": "This dataset represents mine density within individual local and accumulated upstream catchments for NHDPlusV2 Waterbodies based on mine plants and operations monitored by the USGS National Minerals Information Center. Catchment boundaries in LakeCat are defined in one of two ways, on-network or off-network. The on-network catchment boundaries follow the catchments provided in the NHDPlusV2 and the metrics for these lakes mirror metrics from StreamCat, but will substitute the COMID of the NHDWaterbody for that of the NHDFlowline. The off-network catchment framework uses the NHDPlusV2 flow direction rasters to define non-overlapping lake-catchment boundaries and then links them through an off-network flow table.  The National Minerals Information Center canvasses the nonfuel mining and mineral-processing industry in the United States for data on mineral production, consumption, recycling, stocks, and shipments. Mine plants and operations for commodities are expressed as points in a shapefile that was downloaded from the USGS directly. The (mines / catchment) were summarized and accumulated into watersheds to produce local catchment-level and watershed-level metrics as a point data type.",
