Default Cooling towers.... not always

You must of seen the big cooling towers near the reactor.
Some nuclear plants have cooling towers, but others (like nearby Seabrook Station) don't. Seabrook has a massive tunnel going into the ocean to cool the water.

From the picture link, you can see - no tower! But, I don't think it is close enough to the lake to be the root cause

Your mostly right as Seabrook doesnt use cooling towers but it does have some as a backup for the unlikely evnt of an earthquake closing the intake tunnels.
From an article:
That step requires federal approval because the cooling tower is used as a failsafe in the event a major earthquake closes the tunnels that bring seawater into the plant to cool the reactor.

Good Lord!

4 degrees for a low on Saturday, 7 degrees for a low on Sunday, 9 degrees for a low on Monday, more snow on Wednesday and Thursday.... Being at my camp with an umbrella drink on April 1st is definitely out!! At this rate, I'm hoping to be out there May 1st!!! I hate the month of March!!

Rant mode off...

I feel your pain Dan. I'm trying to find a silver lining in all this and it is: all this snow will insultate the ice someone from the frigid overnight temps this weekend and hopefully prevent ice GROWTH. Meanwhile, I'm hoping the ice is being eaten away from the water below. With higher sun and most daytime temps above freezing (except this weekend)...I've got hope that the ice is decaying everyday and that we still see ice out by mid-April (I'm a dreamer).

Boat pickup from storage is March 31....still dreaming....

I drove by Massebessic today and was suprised that the entire west side looks wide open. The east side also looked mostly open with some ice in coves but in front of the park was wide open. I don't usually watch Massy as a sign for how close Winni is to ice out but have to imagine they can't be more than a few weeks apart.

Seeing the open water along the shorelines in the webcams in encouraging as it will give ice room to move in the wind and perhaps crack or weaken...though no signs of that on the big lake yet. I'm disappointed that a few cams are no longer functioning that were major indicators for me. One was Black Cat and the other was in Alton Bay. The remaining cams are not great for progress checking. I may have to take a drive around the lake next weekend.

When I lived in Chester, Massy was my indicator and a great one! When ice was gone at Massy it was exactly two weeks for ice out on winni like clockwork. That is encouraging!

So you're forecasting ice out in 2 weeks? The lows for the next 10 days are all below freezing. I would think they have to be above freezing with highs considerably higher for ice out.

Berlin was -21 this am without the windchill factor.

No I’m not as Mike only said ice was mostly gone but not all gone. There will probably be some refreezing with this cold weather. Once ice is ALL gone on Massy it’s has been my experience, or at least for a ten year span, that ice will be out on winni in two weeks thereafter...

Yes, it is encouraging that we are getting closer to summer. But, if you have docks on the lake the movement of the ice in the spring can cause major damage. Even if you run a circulator all winter the spring movement of multi ton icebergs can wipe out your dock or damage your waterfront in seconds.

That is discouraging! Been there and paid the price!

If you have an ice eater, controlled by a timer/temperature switch, you may have been surprised yesterday afternoon, about 4-pm, when your ice eater powered up, splishy-splashy, for the first time in maybe two weeks.

What was not so small areas of open water, expanding like 'The Blob', has re-froze back to ice ..... could be this winter's last blast?

If I remember correct, the tropic of cancer for the Unites States, is located between Florida and Cuba, somewhere in the ocean out there; on Tuesday, March 20, 2018 at about 4-pm, the sun will be directly overhead at noon, with 12-hours daylight, and 12-hours night, and marks the start of the spring season by custom in the U.S.

When the sun is over the tropic of cancer the date is June 21, the start of summer. For the start of spring it is over the equator.

This is today's view from space once again showing the stark contrast between Winnipesaukee and Sebago which has a very large area of open water.

Is there an explanation for the difference in ice between the Lakes? I'm surprised Sebago is so open.

Thanks.
That satellite picture is remarkable.
Every other lake besides Sebago is ice.

Default Lily Pond

Well I'm depressed...going by Lily Pond this morning it is still locked up tight! Even the shoreline is still solid as a rock not a speck of open water showing anywhere!!

From my vantage point overlooking the big lake it is still fully ice covered and solid. I see zero progress with ice melt over the last three weeks. The lake is snow covered and even most of the shoreline is still somewhat solid! This month of march really screwed us!

My umbrella drink on April 1st at my camp will only happen if I take an airboat out to Welch!!! Does that count??...

Dan
