Description:
Abstract:

This data set consists of boundaries of the NAWQA Surface-Water Regions (formerly called Major River Basins) proposed for regional synthesis in cycle II of NAWQA. Although boundaries of some of the NAWQA study units are likely coincident with Surface-Water Regions, the boundary lines depicted in this coverage don't necessarily match the full resolution study unit boundaries in the NAWQA study unit coverage.

Purpose:

This is one of the GIS base layers developed for analysis of water-quality data.

Supplemental_Information:

The source of the data is the 1:2 million Hydrologic Unit Boundaries (November 2002) in the National Atlas.

NAWQA Surface-Water Regions are combinations of Water-Resources Regions (2-digit HUCs) and are referenced in the coverage by a number from 1-8.

2----- South Atlantic-Gulf and Tennessee: ACFB, ALBE, GAFL, MOBL, SANT, SOFL, TENN
3----- Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy: EIWA, LERI, LIRB, part of MISE, part of OZRK, UIRB, UMIS, WHMI, WMIC
4----- Missouri: CNBR, KANS, part of OZRK, SPLT, YELL
5----- Lower Mississippi, Arkansas-White-Red, and Texas-Gulf: ACAD, CACI, MISE, part of OZRK, SCTX, TRIN

7----- Pacific Northwest:  CCYK, PUGT, USNK, WILL
8----- California: SACR, SANJ, SOCA
------ None: COOK, OAHU (excluded from this coverage)

Polygons representing the 8-digit hydrologic units (cataloging units) downloaded from the National Atlas 03/05/2004.

Process_Step:
Process_Date: 20040305
Process_Description:
Downloaded export file e_hucs00 from National Atlas map warehouse and imported to coverage. Re-projected from geographic to Albers projection.

Selected the cataloging units in the water-resources regions comprising each Major River Basin and made 8 individual MRB coverages each coded by MRB. Polygons coded as water (PLYTYPE NE 0) are excluded.

Process_Step:
Process_Date: 20040618
Process_Description:
Dissolved on MRB and appended the 8 intermediate coverages together to form a national coverage.

Process_Step:
Process_Date: 20040908
Process_Description:
Revised REG 4 and REG 5 as requested by Dave Mueller. REG 5 is the Missouri River Basin (HUC region 10.) Changed the field called MRB to REG to match revised terminology. Revised names to match Water Resources Region names.
