The objectives of this report are to 1) understand the spatial extent and distribution of permafrost in the Alberta-Northwest Territories transboundary region, 2) identify areas most vulnerable to gradual permafrost thaw, and 3) review literature of the current state-of-knowledge on potential impacts of permafrost thaw on water quality and quantity in transboundary regions. To support the Bilateral Water Management Agreement (BWMA) signed between the Governments of Alberta (AB) and the Northwest Territories (NT) in 2015, knowledge and data gaps are identified for the transboundary region.
