Maps - Protected Water Supplies

The Department of Environment, Water Resources Management Division maintains a list of Protected Water Supplies in the Province and also a GIS layer depicting the geographic boundaries of these supplies. A protected supply can be either Surfacewater (SW) or Groundwater (GW) based and are further broken down into the following two categories:

  1. Protected - these are supplies protected under Sections 39(1) or 61(1) of The Water Resources Act, SNL 2002 cW-4.01. The protection of these supplies is approved by various agencies through the Inter-Departmental Land Use Committee (ILUC) and published in the Newfoundland Gazette. Under the Act the Department may restrict activities in the protected area that have an adverse affect on water quality. The legal boundary of a Surfacewater protected supply is usually depicted by straight lines and the GIS layer may also show areas of natural drainage to the supply that are outside the protected legal boundary. The legal boundary of a Groundwater protected supply can be either a circle centered on the wellhead or a polygon which has been delineated by a hydrogeological study.
  2. ILUC - these are supplies that are currently moving through the ILUC process described above with the goal of protection under Sections 39(1) or 61(1) of The Water Resources Act, SNL 2002 cW-4.01. This is a "red-line" layer that is subject to change and provided as a convenience to approving agencies for the purpose of review.

The Division also maintains a list of Unprotected and Potential supplies and further information on these supplies is available in GIS format only.
