"The water level of Lake Nipissing is declining but still remains high and shoreline areas are vulnerable to winds and wave action. Water levels may fluctuate in response to southwest and west winds, which can temporarily enhance local water level by 10-15 cm," said Angela Mills, NBMCA Flood Duty Officer. "The water level of the Ottawa River at Mattawa has returned to seasonally normal conditions and are forecast to decline gradually.”
