Water levels on the Chemainus River are high following heavy rainfall, prompting a high water level advisory. River Forecast Centre said warming temperatures are contributing to rising water levels and localized overflow in streams and rivers. “There’s potential for rising water levels on roads and riverbanks,” the centre said. Emergency Management Cowichan said elevated water levels can result in flooding, environmental contamination and public health risks, including contaminated drinking water. Emergency Management Cowichan said it will provide another update at 1 p.m.
