Instream Works

Main graphic

You have accessed this website to obtain further information on Best Management Practices (BMPs) in and about a stream. If your project involves any work in and about a stream, you will need to ensure that you:

  • apply the appropriate General BMPs to fulfill the Water Act Regulation's Protection of Habitat Section 42(1) and Protection of Water Quality (Section 41) Standards; and,
  • understand the federal Fisheries Act and ensure that you are in compliance with Section 35 of the Act which prohibits the Harmful Alteration, Disruption or Destruction (HADD) of fish habitat and Section 36 of the Act which prohibits the release of deleterious substances to a watercourse. Every effort should be made to incorporate applicable Regional Operational Statements into your project. Operational Statements outline measures and conditions for avoiding HADDs to fish habitat and thus allow works to proceed in compliance with subsection 35(1) of the Fisheries Act.

If you are unfamiliar with the guidebook, please use the flowchart to ensure your project meets all the applicable Best Management Practices.
