Service Description: Arctic grayling are classified as Sensitive in the current General Status of Alberta Wild Species report. Alberta's Endangered Species Conservation Committee (ESCC) has identified Arctic grayling as a Species of Special Concern — a species that without human intervention may soon become threatened with extinction. Populations of this fish have decreased over the past few decades due to (1) Increased accessibility by humans to remaining habitat, resulting in increased harvest, and (2) blocked migration routes and altered stream flow resulting from improperly placed culverts in newly constructed roads.The Hydrologic Unit Code (HUC) Watersheds of Alberta represents a collection of four nested hierarchically structured drainage basin feature classes that have been created using the Hydrologic Unit Code system of classification developed by the United States Geological Survey (USGS) with accommodation to reflect the pre-existing Canadian classification system. The pour points associated with the delineation of these watersheds have also been included as a point feature class. The HUC Watersheds of Alberta consist of successively smaller hydrologic units that nest within larger hydrologic units, resulting in a hierarchal grouping of alphanumerically coded watersheds feature classes. These nesting watersheds feature classes were created using ArcHydro Tools v.2 (Alberta Environment and Protected Areas) and are subject to periodic review and update. There are currently individual feature classes for HUC 2 (coarsest level), HUC 4, HUC 6, HUC 8 and HUC 10 (finest level). This dataset is produced for the Government of Alberta and is available to the general public.
