Chemainus Wells Testing Program

The Municipality of North Cowichan (MNC) submitted an application to the BC Environmental Assessment Office (BCEAO) on March 31, 2015, to amend the existing BCEAO Certificate #W09-01 to be able to run the Chemainus Wells year round.  Presently, operation of the wells is restricted to the period between October 15 and June 15.  The Amendment Application asks for approval to run the Chemainus Wells between June 15 and October 15 yearly, in addition to the presently approved October 15 to June 15 operation.  The presently approved maximum well pumping rate of less than 75 litres per second will remain.  The application commits to continue monitoring aquifer and river levels and temperatures.  The application also includes a requirement to release up to 75 litres per second continuously from Holyoak Lake via Banon Creek to the Chemainus River during the June 15 to October 15 period.  The full application can viewedhere.

In support of this application, MNC will be operating the wells and supplying the community of Chemainus with water from the wells from time-to-time in September.  Further testing and investigation of the potential impact of well pumping on the flow in the Chemainus River and the release of water from Holyoak Lake to the Chemainus River as a mitigation measure will be undertaken during this time.  During the testing program, water not used by the community will be discharged to Fuller Lake and Askew Creek.  Click on the links below to view the testing program and the BCEAO's approval for the testing program.
