Maps are important tools to share and compare information. Available water stewardship-related maps:


Watersheds of the Northwest Territories 

This map includes all watersheds of the Northwest Territories (NWT) to the sub-basin level. The Mackenzie River Basin, Canada’s largest river basin, is also highlighted along with its sub-basins.To view the established and candidate protected areas in the sub-basins of the NWT click here.


Water Monitoring Sites in the NWT

  • This map includes all active water quality monitoring stations in the NWT (as of February 2016) coordinated by government agencies. For additional nformation about current and past water quality and quantity monitoring sites, see the NWT Water Monitoring Inventory. The inventory (last updated in 2013) includes monitoring undertaken by federal, territorial and Aboriginal governments, communities, and industry.
  • This map includes 2014 sampling sites part of the NWT-wide Water Quality Community-based Monitoring Program.   


Community catchment maps

As part of GNWT Environment and Natural Resources (ENR) 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 ENR’s Forest Management Division. The community catchement maps can be accessed here, from the NWT Centre for Geomatics website.

Ecosystem Classification Maps

With the NWT Ecosystem Classification Photo Map you can view the thousands of photographs collected as part of the NWT Ecosystem Classification program, visually documenting the NWT landscape.

  • Photos taken along the displayed flight lines are viewable by zooming in to a minimum scale of 1:1,000,000 then hovering over a photo point to pop-up the image(s) at that location. Once zoomed in, the flight lines turn off and the photo points become visible.
  • You can also generate reports of a selected photo(s) and its attributes by using the 'Create a Photo Summary Report'. Use the drawing tools to make a selection.
  • Both map viewers can be launched in a web browser.
  • The browser requires Silverlight 4.0 plug-in and minimum screen resolution of 1024x768.


Inventory of Landscape Change Webviewer Map

The NWT Cumulative Impact Monitoring Program (CIMP) launched the Inventory of Landscape Change webviewer in July 2016.  The online mapping tool allows you to display, manage and download human and natural disturbance information for the NWT.

Spatial Data Warehouse

A web map viewer of publicly available data sets is provided on behalf of the GNWT.  The web map viewer provides a means of mapping geospatial information, satellite imagery and aerial photography over the internet. To access the GNWT Spatial Data Warehouse, click here.
