Eastern Region
ATLANTIC CANADA
The melt is on. With increased periods of sun and higher temperatures, the majority of the snow covering Atlantic Canada has already disappeared. Although the past few weeks have been free of snowfall, small amounts have fallen recently, with the majority of accumulations in southern New Brunswick and western Nova Scotia. The relative water equivalency (determined by snow cover and snow density) is normal in much of northern New Brunswick, but is high in southern parts of the province. Relatively late, mild temperatures, followed by early snow cover, have limited frost penetration in many areas, which will allow for ground seepage rather than runoff in the spring.
This year's spring freshet may be smaller than normal, with below normal water equivalency, reduced frost and a slow thaw, coupled with seasonal daytime temperatures and below-freezing nights. Although there may be less runoff in some areas, southern New Brunswick, western Nova Scotia and western Prince Edward Island will likely have more water than normal due to above average winter snowfall. Overall, an average spring is expected, with normal operating levels maintained in DUC projects, and many spring seasonal wetlands available for migrant waterfowl.
Many rivers are now open and common goldeneyes have been observed on the St. John River (see photo). Reports of migrants in Prince Edward Island, including wigeon, confirm that spring is indeed here.
The long-range forecast is calling for seasonal temperatures and snow. An average water supply is expected, and spring habitat should be suitable for migrants. Shallow water wetlands will begin to thaw soon, likely earlier than normal due to thin ice and warm temperatures.
