Columbia Basin Water Quality Project (CBWQ)

Mainstreams has coordinated the CBWQ since 2007 and has received funding for the 2016-2017 fiscal year.  The program began as a result of recommendations from the Columbia Basin Watershed Network Symposium in 2005 that the Trust build capacity in local watershed groups to monitor their water.   A training program involving watershed groups from all over the Columbia Basin was held in Kimberley in 2006; during that workshop the CBWQ was born.

Partner groups follow the same Environment Canada CABIN (Canadian Aquatic Biomonitoring Network) protocol and are actively monitoring wadeable streams seven months per year.  CABIN focuses on the health of benthic macro invertebrate populations and is used by governments across Canada.

CBWQ exists as a result of the funding support from Columbia Basin Trust.  The project is coordinated by Laura Duncan who chairs the CBWQ  Steering Committee.  Mainstreams Environmental Society in Kimberley, BC administers the project.
