Official 2015 Ice-In Thread

[BroadHopper]

Sebago Lake does freeze over, usually after Winni and Sebago usually ice out before Winni. Not sure why.

Lake Tahoe never freeze. Some facts to ponder:

The average temperatures for the winter months at Lake Tahoe are
December: 14 degrees Fahrenheit,
January: 15 degrees,
and February 17 degrees.
These temperatures are not cold enough to freeze such a large expanse of water.

Some statistics about the Lake may help you to see why it doesn't freeze.
Though sitting at an elevation of over 6,200ft:
Lake Tahoe is 22miles wide by 12miles long
1645ft maximum with an average depth of 989ft
The lake's surface area is 122,200 acres
With a volume of 39 trillion gallons
And
The sun shines at Lake Tahoe during 75% of the year, or 274 days.

Broadhopper,

I've been on Sebago for over 40 years. It freezes completely only about 40 percent of the time.

[Pineedles]

It has to be the depth of Sebago. Much deeper than Winni.

[Happy Gourmand]

Certainly that must be a factor. Sebago is Ave depth 107' deepest 316' Winni ave depth is 43' deepest 212'

[Blue Thunder]

Yes, depth is a factor but the biggest factor is that Big Bay as it is called, is far larger an expanse of water than the broads is and is "almost" never calm. Wind of some kind is always a factor. Even on the coldest calmest night below zero it will not freeze and if it does, the wind comes up and blows it off to shore the next day. I have many pictures of my kids standing on ten to twelve foot high piles of ice on our shore front.

I'm expecting ice in to be declared today...

I believe you are quoting the nighttime lows. The winter highs for Tahoe are in the forties, making the overall temperature right about freezing. The average Winnipesaukee air temperature in the winter is in the low twenties, some eight-to-ten degrees cooler.

Water volume is not all that important as evidenced by Lake Baikal (150 times the water of Tahoe and frozen 4 months a year). Once the water temperature is lowered to 39F (4C), only the first foot of water needs to be cooled further. Even in the dead of winter, the lake's bottom is at 39F (4C).

However, I, too, have no idea why Sebago doesn't freeze each year.

I wonder whether the predicted heavy rain and warmer temps will cause problems with the newly formed ice?

[Just Sold]

Looking good in Alton Bay and 19 Mile Bay today 1/17/15

[IslandRadio]

Ok, this may sound dumb, but what does ICE IN mean exactly?

I know what Ice Out means - and it doesn't mean there's no ice.

What is the definition of Ice In?

Sorry for the dumb-ish question

[Resident 2B]

I am not aware of an official definition. Some years, the lake never completely freezes, yet we have an official ice out for that year. So, I believe it could be possible to have ice out without and ice in.

My only concern is once ice in is declared, some people will think the ice is completely safe everywhere on the lake. Be aware, the ice has varying thicknesses and is not safe everywhere!

[Slickcraft]

We walked from Ellacoya up Scenic Rd this morning; the ice singing was loud and continuous. While the direction was well distributed the main chorus seemed to from between Welch and Diamond out toward the Broads.

[Smith Point]

I’ve got another stupid question. With all the bob houses in Alton bay, is there fish that deep in the bay, or is it easy excess to the lake and a good place to hang out?

I do not think there is a definition. It seems that it gets called when there is no open water as seen from the air. It does not mean it is safe. I for one would not ever call ice in. Some idiot would sue if they fell through the ice.

Ice out is "official" when the Mt. Washington can make it to all ports, right?

[Island Girl]

There is a stream of open water in front of my dock. You can see it on Snake Eyes. Is there any other open water?

My understanding is that this is the official definition for ice in and ice out is the mount route open or not.

If this was the case, then "ice-in" should have been declared weeks ago.

I still do not think we have an official definition, although over the last ten years or so, it has been called when ice covers the entire lake.

R2B

[tis]

I don't think we have an official definition either. There was never before such a thing. But then, the definition of ice out was not always when the Mount could make it's way to all it's ports either. Emerson Aviation didn't always fly around and declare ice out.

[pcmc]

Imo,
Ice in = zero open water, the surface of the lake is shore to shore frozen.

Ice out = zero remaining ice, dive in.

[Pineedles]

According to Wikipedia, there appears to be misconceptions about even Ice-Out. So I would surmise that there is nothing definitive for Ice-In either!

IG, I don't see that same stream of water on the other end. But I can't imagine today is a good ice growing day.

Gee that's a cold looking picture.

I'm surprised to see so many leaves still on the trees.

[Idylltimer]

Has anyone been crossing from Cattle to Bear?

[BroadHopper]

As of this morning, there is a patch of open water off Oak Street in Laconia. Winnisquam usually freeze before Winnipesaukee.

The I S S airboat has been parked there, next to the dock and in the open water created by the water circulators for a couple weeks, and comes and goes out to Mark Island, so it's difficult to say how safe is the ice close to the floating dock there?
