Fish Consumption Guidance

Fish Consumption Guidance

Site Specific Fish Consumption Advice

The GNWT works in partnership with the Federal Government to test for contaminants and human health risks in most NWT rivers and lakes on a yearly basis.

Below you will find fish consumption guidelines for the following lakes and rivers. 

Akaitcho Region

Dehcho Region

Sahtu Region

Yellowknife Region

Precautionary recommendations have been provided not to consume fish from certain lakes in the Yellowknife area due to environmental contaminants in water in the absence of data on contaminant levels in fish. As new information on fish becomes available, this advice may change. For details on these lakes, please see the public health advisory here:

The Department of Health and Social Services does not conduct environmental monitoring of contaminants in wildlife and the environment; however, it engages with research programs such as the Northern Contaminants Program (NCP) and the Cumulative Impacts Monitoring Program (CIMP) to maintain an awareness of current research and emerging information so that public health messaging can be updated when necessary. Additional research and monitoring is conducted by various agencies, including Department of Fisheries and Oceans Canada, Environment and Climate Change Canada, and independent researchers. For more information on environmental research and monitoring in the NWT, please see:
