This layer is a subset of the National Hydro Network NHN Index displaying the Nelson River Drainage Area.

The National Hydro Network (NHN) focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial digital data compliant with the NHN Standard such as lakes, reservoirs, watercourses (rivers and streams), canals, islands, drainage linear network, toponyms or geographical names, constructions and obstacles related to surface waters, etc. The best available federal and provincial data are used for its production, which is done jointly by the federal and interested provincial and territorial partners. The NHN is created from existing data at the 1:50 000 scale or better. The NHN data have a great potential for analysis, cartographic representation and display and will serve as base data in many applications. The NHN Work Unit Limits were created based on Water Survey of Canada Sub-Sub-Drainage Area.

This layer was subset to create layer of the area of focus. 

NOTE that the drainage area created from the NHN layer is of different coverage than the Nelson River area created using the PFRA AAFC shapefiles (https://canwinmap.ad.umanitoba.ca/maps/142).

This data is a subset of data from the National Hydro Network Geobase Series.
