Procedures_Used: Northern and eastern portion of drainage basin delineation was digitized from USGS 1:63360 quads with an RMS error of < 0.007. The quads used are as follows:
Norton Bay A-1, A-2, A-3, B-1, B-2 Unalakleet B-2, B-3, B-4, C-2, C-3, C-4, D-2, D-3
Coverages were edited, built, mapjoined, edited and rebuilt. The mapjoined coverage was then joined to the HUC 1:250,000 coverage from Unalakleet for the western and southern boundaries. The resulting coverage, UNALAK_DA was edited and built.
