Title: Whirling Disease Decontamination Zones
Dataset Publication Date: 2017-06-14
Abstract: This GIS dataset covers the four types of decontamination zones for whirling disease in Alberta, and identifies the inherent risk categories for each. These boundaries are to be used by Government of Alberta field staff and industry, as described in the Alberta Decontamination Protocol for Watercraft & Equipment. Confirmed Red Zones are zones with CFIA confirmed positive testing for whirling disease and are based on a HUC 10 level as found in the HUC Watersheds of Alberta dataset. Irrigation Red Zones are similar to confirmed red zones, however are based on Irrigation District boundaries and only apply to irrigation canals.Yellow Zones represent high to moderate risk for the introduction/spread of whirling disease due to one or more of the following criteria: susceptible salmonid species present, high recreational activity/use and access to water, and high population base. White Zonesdo not have any confirmed cases of whirling disease and represent lower risk due to lower population base and less activity/use.

Data Quality Information
Scope (quality information applies to): Dataset
Data History: These zones are based on the HUC Watersheds of Alberta and Irrigation Districts datasets. Red Zones are HUC 10 watersheds that contain fish samples that tested positive for whirling disease, and Irrigation Red Zones (that apply only to man-made irrigation canals within the zone) are based on Irrigation Districts that are adjacent to Red Zones or known areas where the spread of whirling disease is high.
