Every week during the ‘control’ season when the weir spill gates and boat locks and is in use (closed or partly closed), Catalyst Paper Mill’s Environment Manager provides an update by email to anyone interested. Excerpt below re-posted with permission. The full update can be viewed at https://www.catalystpaper.com/page/cowichan-water-management-information
Weekly email update from Catalyst Paper, May 19 2020:
Good morning everyone,
Conditions remain very good with lake holding at 100% full. River flow from Cowichan Lake is at 17 cms this morning and current minimum authorized river flow is 15 cms. With lake full and with some wet weather in forecast for this week it is possible flow will remain above 15 cms.
Snow pack is melting and as of current snow pack reading, there is now as much snow in the hills as there was in total last year.
A flow of 15 cms will be sustainable through to the end of that fisheries flow window ending on June 15.
