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, Brian Houle, provides an update by email to anyone interested. Re-posted with permission.

Conditions in the watershed remained mostly dry since the last wet spell that partly refilled the lake.
Flow from the lake is being controlled to 25 cms and this high spring flow is a fisheries guided flow target.
I have been asked many times why the flow is so high and the simple answer is, the fish need these higher flows in the spring.
The high flows are needed by the young fish that are emerging from the gravel as the eggs hatch in the spring.
