...Ice Safety...

Temperatures have been very warm this winter, and most areas
across northern and eastern Maine have had their warmest November
through January on record. The warmer than average temperatures
combined with several rain events have led to lower than average
ice thickness in many areas. Also, the quality of ice in many
areas is poor. It is important to keep a few things in mind:

1. Areas that have historically been safe for outdoor activities
such as skiing or snowmobiling may or may not be safe this year.

2. There are likely large variations in the ice thickness over
short distances. Just because the ice is safe in one location, does
not mean that an entire pond or lake is safe.

3. Rivers are of particular concern this year as there has been
above average runoff from melting snow and rain.

4. The ice quality in many areas is likely only poor to fair.
Clear ice is usually more solid than white or grey opaque or snow
