Description:
Abstract:
These data represent the watershed of the Northern Gulf of Mexico as recognized by the Northern Gulf Institute (NGI). They have been adapted from the USGS 1:250k Hydrologic Units for the continental United States
Purpose:
The purpose of these data is to graphically represent the entire NGI watershed as well as provide the ability to conduct analyses at the local level based on USGS Hydrologic Unit Code (HUC) Cataloging Units.
Supplemental_Information:
These data, representing only the NGI area of interest, are a subset of the USGS 1:250k scale Hydorologic Units of the United States.

Attribute_Definition:
Regions - These geographic areas contain either the drainage area of a major river or the combined drainage areas of a series of rivers.
Attribute_Definition_Source: US Geoglogical Survey
Attribute:
Attribute_Label: SUB
Attribute_Definition:
Subregions - A subregion includes the area drained by a river system, a reach of a river and its tributaries in that reach, a closed basin(s), or a group of streams forming a coastal drainage area.
Attribute_Definition_Source: US Geoglogical Survey
Attribute:
Attribute_Label: ACC
Attribute_Definition:
Accounting Units - These hydrologic accounting units nest within, or are equivalent to, the subregions
Attribute_Definition_Source: US Geoglogical Survey
Attribute:
Attribute_Label: CAT
Attribute_Definition:
Cataloging Unit - A cataloging unit, the smallest element in the hierarchy of hydrologic units, is a geographic area representing part or all of a surface drainage basin, a combination of drainage basins, or a distinct hydrologic feature. These units subdivide the subregions and accounting units into smaller areas.
