The water equivalence in the snowpack for the Peterborough-Bancroft district on March 1st ranged from 100% to 130% of normal for this time of year. More recent snow station results indicate that the snowpack has remained largely unchanged to date.
Lakes and Rivers in the area are still at seasonal levels. Levels will rise as a result of increased runoff over the coming days. Runoff will then slow as temperatures cool to more seasonal values Sunday and Monday night.
