On the cover page of the Getting to Know Your Watershed manual is a map that contains a delineation of the 14 major watersheds or river basins in Georgia. On the inside of the cover page is a map that delineates the 52 watersheds in Georgia. The 52 watersheds are smaller watersheds within the larger river basins. They are labeled by common name and by an 8-digit number. The 8-digit Hydrologic Cataloging Unit (HUC) is part of a national coding system. HUC units can range from 2 to 16 digits: the larger the number, the smaller the watershed. Therefore, the 14 major river basins on the front cover will have smaller HUC numbers. For the purpose of grouping and tracking the AAS monitoring sites, please indicate which of the 52 watersheds your waterbody is in, using common name and the 8-digit HUC. For example, if you live in Cherokee County, you can see on the map that you are in the Etowah River watershed and that its HUC number is 03150104.
