Great Lakes (Hydrologic Region 04)
The Great Lakes drainage area is composed of hydrologic regions 04.
The Great Lakes hydrologic regions are further divided into production units: 04 a, b, c, and d.
NHDPlus Shapefile and DBF components are distributed by hydrologic region.
NHDPlus ESRI Grid components are distributed by production units.
