Auxiliary Spillway
At its meeting held July 20, 2015, Nanaimo City Council unanimously voted in favour of a motion to proceed with the construction of an Auxiliary Spillway adjacent to the Lower Colliery Dam. The Auxiliary Spillway option was chosen from one of three options identified by the Province of British Columbia's Dam Safety Section's April 29, 2015, 'revised' Order requesting remediation of the Lower Dam.
Construction of the spillway was completed in the spring of 2016.
