Continued warm and dry conditions have prompted the province to elevate the drought rating in for east Vancouver Island, to Level 4.
As a result, a maximum reduction of water use is recommended and regulatory action may become necessary.
West Vancouver Island remains at Level 3 and will be re-evaluated as conditions deteriorate.
If voluntary reductions of water use are not sufficient to maintain flows above critical levels, the province may consider regulating water usage under the Water Sustainability Act.
These include, but are not limited to, the Koksilah, Chemainus, San Juan and Salmon rivers.
Recent precipitation has been insufficient to halt the downward trend on all of the east Vancouver Island streams.
Maximum water conservation is encouraged in these and other low-flow watersheds.
Water users on all streams are reminded to ensure that water intakes are screened to Fisheries and Oceans Canada standards to prevent fish from being pulled into water systems as water levels drop.
Residential, agricultural and industrial water users who are located within municipalities and regional districts are encouraged to observe local water conservation bylaws where they exist.
Some water conservation tips for residents include limiting outdoor watering, not water during the heat of the day or when it is windy, taking shorter showers and installing water-efficient shower heads, taps and toilets.
