Whirling Disease (AIS) Decontamination Zones
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. (1) 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 Hydrologic Unit Coded 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. (2) 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. (3) White Zonesdo not have any confirmed cases of whirling disease and represent lower risk due to lower population base and less activity/use.
