A dataset containing identifying information for all lakes > 1ha. This includes lake name, lake size (area and perimeter), location (lat/long), elevation, and codes identifying zones in which the lake is located.

Format

A data frame with 141265 observations of 17 variables:

  • lagoslakeid: unique identifier for each lake in LAGOS-NE. For each row of data in this table, the lagoslakeid identifies the focal lake for which other measures are calculated

  • nhdid: the 'Permanent_identifier' from the NHD, but is called the NHDID in LAGOS-NE

  • gnis_name: lake name from the GNIS database

  • nhd_lat: latitude of centroid of the NHD lake polygon in decimal degrees (NAD83)

  • nhd_long: longitude of centroid of the NHD lake polygon in decimal degrees (NAD83)

  • lake_area_ha: surface area (in hectares) of lake waterbody polygon from NHD

  • lake_perim_meters: perimeter (in meters) of lake waterbody polygon from the NHD

  • nhd_fcode: NHD five-digit integer code with feature code plus additional characteristics/values

  • nhd_ftype: NHD three-digit integer code providing a unique identifier of feature type for the waterbody

  • iws_zoneid: the unique ID of the IWS that is estimated for the focal lake in the row of data that is identified by the lagoslakeid.

  • hu4_zoneid: the unique ID of the HU4 zone that the focal lake is located within

  • hu6_zoneid: the unique ID of the HU6 zone that the focal lake is located within

  • hu8_zoneid: the unique ID of the HU8 zone that the focal lake is located within

  • hu12_zoneid: the unique ID of the HU12 zone that the focal lake is located within

  • edu_zoneid: the unique ID of the EDU zone that the focal lake is located within

  • county_zoneid: the unique ID of the county that the focal lake is located within

  • state_zoneid: the unique ID of the state that the focal lake is located within

  • elevation_m: the elevation of the lake centroid, in meters (referenced to the North American Vertical Datum of 1988 (NAVD88)) and obtained from the National Elevation Dataset
