Hydrologic Unit Code 8 Watersheds of Alberta

Alberta Environment and Parks, Government of Alberta 20110615 Hydrologic Unit Code 8 Watersheds of Alberta vector digital data https://maps.alberta.ca/genesis/rest/services/Hydrologic_Unit_Code_Watersheds_of_Alberta https://maps.alberta.ca/genesis/services/Hydrologic_Unit_Code_Watersheds_of_Alberta/Latest/MapServer/WMSServer This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. 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 Parks) 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). These are all contained within a single feature dataset. The HUC Watersheds of Alberta co-exists with the Watersheds of Alberta (GOA) as well as a number of other non-GOA watersheds datasets such as the Prairie Farm Rehabilitation Administration watersheds data published by Agriculture and Agri-Food Canada. The alphanumeric watershed coding follows the USGS system and also has a direct link to the Environment Canada Water Survey of Canada coding (as outlined by departmental Water Policy and Operations staff). Where possible, Water Survey of Canada regions (00XX level) were approximated by the HUC 6 level of delineation but some exceptions will be noted. Further delineation past the HUC 10 level may be required where smaller, more refined watershed units are needed. More information on the USGS hydrologic units can be found at http://water.usgs.gov/GIS/huc.html. It should be noted that the HUC Watersheds of Alberta feature class polygons may be represented as multipart polygons (i.e. there may be only one record in the database associated with more than one polygon). Multipart polygons are typically located in the same watershed or basin where by two (or more) polygons flow into another province or territory. Multipart polygons may be exploded into single part polygons if required. The Hydrologic Unit Code 8 Watersheds of Alberta is a feature class within the Hydrologic Unit Code Watersheds of Alberta feature dataset that represents a seamless basin-wide coverage that falls completely within the Hydrologic Unit Code 6 Watersheds of Alberta. The coding is an eight-digit numeric code with the last two digits representing the unique identifier for the HUC 8 watershed. The first six digits represent the enclosing HUC 6 watershed. There are 422 polygons within this feature class ranging from five to 5 593 square kilometres in area with a mean area of 1 570 square kilometres. Most of the HUC 8 watersheds are larger than 100 square kilometres and are typically more than 500 square kilometres in area. There are four watersheds that are co-incident with the HUC 2 watersheds, five watersheds that are co-incident with the HUC 4 watersheds and 27 watersheds that are co-incident with the HUC 6 watersheds where the enclosing watersheds have not been subdivided. There are generally one to 45 subdivisions of the HUC 2 watersheds, one to 18 subdivisions of the HUC 4 watersheds and one to five subdivisions of the HUC 6 watersheds present. The HUC 8 watersheds have been attributed with the Water Survey Canada region code and a basin name. The basin names follow the names associated with the HUC 2 watersheds but not the names associated with the Watersheds of Alberta 2011. The HUC 8 watersheds have not yet been further subdivided. Note that this dataset replaces the Hydrologic Unit Code Watersheds of Alberta released on October 16, 2015. An area of approximately 3 381 hectares was deleted from HUC 11010404 (ELK RIVER) and appended to HUC 11010401 (BRAZEAU RIVER). The area amended is deemed to be part of the Brazeau Reservoir as opposed to the Elk River. Update March 09, 2017 – The section of the Red Deer River immediately downstream of the Gleniffer Lake Dam was appended to HUC 08010301 (RED DEER RIVER AND SYLVAN LAKE). The area was removed from HUC 08010201 (RED DEER RIVER AND GLENIFFER LAKE) and was approximately 2700 hectares in size. Update May 07, 2021 - Portions of the Belly (04010302) and Waterton (04010301) River watersheds were modified. Original delineations had the Lower Belly River as part of the Waterton River. This portion of the Belly River has been added to the Belly River Watershed HUC8, and was approximately 60,720 hectares in size The Hydrologic Unit Code Watersheds of Alberta collection of feature classes is intended to define hydrologic units that form a standardized baseline which covers the province of Alberta. Successively smaller hydrologic units are nested within larger hydrologic units to create hierarchal watershed boundaries. These standard units are based on sound hydrologic principles (flow direction) and have been reconciled between and within the feature classes that form the dataset. Existing high resolution watersheds or catchment polygons have been collated into larger watershed units to achieve the hierarchical, nested polygon dataset structure. Watershed boundaries will vary between existing watershed/basin GIS layers available from the Government of Alberta and the Government of Canada. The user takes full responsibility understanding the spatial and temporal limitations of the HUC Watersheds of Alberta. More information concerning data sources used can be found within the department using the keywords listed below. Updates to this dataset will not necessarily be performed upon further review of existing watershed units. All rights reserved. HUC Watersheds of Alberta data is subject to change without notice. The Government of Alberta assumes no responsibility for discrepancies at time of use. Watershed unit delineation follows ArcHydro Tools v2 process, as outlined by the ArcHydro Tools Community of Practice (COP). Scale and accuracy of the HUC Watersheds of Alberta mimic the scale and accuracy of data contained in ArcHydro Tools geodatabase.

All of these former data sets are no longer valid and have been superseded by Watersheds of Alberta (GOA). The underlying data used to create the HUC Watersheds of Alberta are associated with various degrees of accuracy. There may be inconsistency in the spatial accuracy as a result. All HUC Watersheds of Alberta feature classes within the HUC Watersheds of Alberta feature dataset have been topologically reconciled between and within the feature classes for boundary alignment and gaps. The geometry has been checked and repaired. This dataset is complete for all feature classes for the province of Alberta. No delineation coarser than HUC level 2 or finer than HUC level 10 is publically available. The positional accuracy of the watershed boundaries will vary according to the accuracy of the source data.
