Recent rainfall has done little to improve water flows in the Cowichan River, according to the most recent data.
Watershed board coordinator Rodger Hunter says now is the time for people to reduce their water usage.
River flows are currently around 4.5 cubic meters per seconds, compared to the 18 meters per second which would be ideal for thousands of salmon waiting to head upstream to spawn.
Hunter says the long term solution, besides reducing water consumption, is to permanently raise the weir in Cowichan Lake by 30-45 cm.
