As part of GNWT Environment and Climate Change (ECC) actions towards Keeping NWT Water Clean within the Managing Drinking Water in the NWT: A Preventative Framework and Strategy, each community's drinking water catchment area was mapped in 2007. In 2011 these maps were updated with more current data as well as new related data, such as developments and activities from the Mackenzie Valley Land and Water Board and forest fire boundaries from ECC’s Forest Management Division. The community catchment maps can be accessed here, from the NWT Centre for Geomatics website.
