Second-earliest Lake Nipissing ice-out date since 1946

Some ice lingered on Lake Nipissing until the weekend but ultimately could not withstand the above-normal temperatures experienced in the region recently.

Helicopters Canada (formerly Essential Helicopters) reports on its Facebook page Lake Nipissing was ice-free as of Saturday, April 10.

Other than the April 8 ice-out date in 2010, this year's is the earliest recorded since 1946, when the lake was clear April 4. The record for the earliest recorded ice-out since 1901 came the year before, April 3, 1945.

This year is also the fifth-earliest ice-out date since recording began in 1901.

The latest recorded ice-out date for Lake Nipissing is May 19, 1926.

Before this year, six of the last eight ice-out dates had fallen in May, with the other two coming in the last third of April.
