Colorado (Hydrologic Regions 14 and 15)
The Colorado drainage area is composed of hydrologic regions 14 and 15.
The Colorado hydrologic regions are further divided into production units: 14 a and b and region 15 a and b.
NHDPlus Shapefile and DBF components are distributed by hydrologic region.
NHDPlus ESRI Grid components are distributed by production units.
