What is a Stream ASsessment?

What we collect:

Stream Assessments:

Watercourse Assessed:

Since the large storm event in 2015, the following watercourses have been reassessed:

  • Second Run Brook
  • Daley Brook
  • Grant Brook
  • Belleisle Creek
  • Reddin Brook
  • Joliffs Brook
  • Elm Brook
  • Midland Brook
  • Stewarton Brook

Stream assessments involve collecting visual, physical, and chemical information about the watercourse, stream banks, and surrounding riparian area. 

Physical parameters:

  • Stream velocity
  • Wetted width
  • Bankfull width
  • Water depth


Visual parameters:

  • Bank erosion
  • Canopy cover
  • Riparian area composition
  • Substrate composition
  • Channel type


Chemical parameters:

  • Water temperature
  • Dissolved oxygen
  • Specific conductivity
  • pH

The following watercourses were assessed between 2013 - 2015: 

  • Bates Brook
  • Hamilton Brook (Glenburn)
  • Peters Brook
  • Reddin Brook
  • Midland Brook
  • Joliffs Brook
  • Elm Brook
  • Belleisle Creek
  • Spragg Brook (lower section)
  • Grant Brook
  • Daley Brook
  • First Run Brook
  • Second Run Brook

The BWC has been doing stream assessments in various waterways since 2013 (13 in total). These assessments help determine where aquatic habitats might be under pressure (stressed) or have already deteriorated to a point in which restoration is needed.  


In September 2015, a large rainfall event ravaged the Belleisle watershed damaging streams and riparian areas, and caused many road and culvert washouts. Since then, the BWC has been re-examining watercourses to determine the extent of damage done and where riparian enhancement efforts should be placed.
