Low Water Advisory Ended: Watershed Conditions Return to Normal

With several precipitation events so far this winter, the watersheds in the Ganaraska Region have recovered to normal conditions. In December 2025, the region received 75mm or 106% of normal rainfall. This has brought stream flows up and is likely resulting in some groundwater recharge where there is little ground frost. The 3-month and 18-month total rainfall indicators are currently at 88% and 82% of normal respectively. When all three rainfall indicators are above 80%, watersheds are considered to be in the normal range. In addition, stream flow indicators are well above normal for this time of year as a result of the winter rain and snowmelt runoff.
