Watershed Monitoring


Coquitlam River Water Quality

The Roundtable identified water quality monitoring as a primary way of contributing to a healthy watershed. In the summer of 2012, the City of Coquitlam initiated the first year of water quality monitoring on the Coquitlam River to help build a current set of water quality data. The data will be used to monitor the health and integrity of the Coquitlam River and to help guide future activities and decision-making processes in the watershed. Samples were collected on a weekly basis during the dry and rainy seasons at seven sites along the Coquitlam River, from just below the Coquitlam River Dam to the downstream end of Colony Farm. The 2013 results showed that twelve out of thirteen parameters tested achieved a ‘green level rating – another year of positive and promising results.  The City will continue the program in 2014.

The RiverWatch Program is a non-technical community-based initiative that started in late 1997 as a pilot project to gather volunteers together to protect and preserve the Coquitlam River watershed through education and awareness. At least once a month, volunteers monitor sections of the Coquitlam River and report their findings. The group has been making small changes along the way and is always open to suggestions for improving the program.

How it all works....

The lower Coquitlam River watershed is divided into 19 different reaches which is walked by RiverWatchers on a monthly basis. The RiverWatchers are asked to make observations related to human activities, litter and pollutants, water quality and wildlife for each reach they walk. The comments from the data sheets are used to develop a monthly newsletter, which will eventually be compiled to form a database.

The lower Coquitlam River watershed is divided into the following reaches ("W' stands for west side of the River and "E" stand for the east side of the River):

  • W-0 Coquitlam Lake Dam to Metro Van. Gate W-1 Metro Van. Gate to 1900 Block Of Pipeline Rd
  • W-2 1900 Block of Pipeline Rd. to Gallette Ave W-3 Spot Check Gallette Ave. to Cortes
  • W-4 Cortes to Patricia Walking Bridge W-5 Patricia Pedestrian Bridge to Lougheed Hwy.
  • W-6 Lougheed Hwy. Bridge to Maple Creek W-7 Red Bridge (Pitt River Rd.) to Mundy Cr.
  • W-8 Mundy Cr. to Community Gardens Parking W-9 Community Gardens Parking to Fraser River
