You maybe correct and at this moment the lake may be where it should be, but the melt off is not up in the mountains where it needs to be. The story will be told a month to six weeks from now when the lake usually tops off. I don't believe it is going to this year.

It is only March 12. We still have 2+ months of spring, which usually brings plenty of rain. If on May 12 the lake is still low, then you might have a legitimate concern, but I don't think you need to worry quite yet.

Looking at the DOWNINGSLANDING CAM the lake seems to be up. The old gas dock is just above the surface.

Yes with the recent rain the lake is up and right now we appear to be in good shape. However knowing some about water tables, long term effects of a bad winter etc. I still remain skeptical...

I believe Chip does indeed have the piece of the equation that we need to allow to unfold some. I believe the amount of rain fall in April, and May could indeed have a huge influence either way on future of the boating season and the lake level for the year.

The dam operators only have so much control.... when water is needed down stream they have no choice but to allow water to flow... I have been looking at more then just lake level data, I have been looking at river flows etc. believe me this winter and its lack of snow has a ripple effect.

But with all the rain down in the southern part of the state I would think they have to slow the outflow at the dam.

Quite a jump in this graph

There may be "not much snow" around the lake shores but this has turned into quite a winter for elevations above 1500 feet. Randolph NH had 39 inches of snow in the storm 2 weeks ago, and more since. Wildcat Mountain has had something like 5 feet of snow in the last 2 weeks and another foot from this current storm. Mt. Major is looking very white right now. It's a great time to go skiing!

Sooner or later, that snow is going to melt and run downhill. The lake is now 5 inches below my approximate-full mark.

[Bizer]

The lake has reached the full mark.

[CanisLupusArctos]

The weather station has received 0.70 inch of rain today and there is more on the way. The mountains are also getting rain from this, so snowmelt is beginning to occur there. Expect the lake to continue rising.

The lake looks about full..

[Lakegeezer]

The water flow at Lakeport dam today is over 1750 cubit feet per second, which is an emergency rate. The lake level is out of control again, at more than a foot above average for April 1. The level is 504.55 which is well above full lake (503.63), near a record high for this time of year (since 1982) and well above the planned limit for anytime during year (504.32). Typical for this time of year is 502.75 to 503.75. We are expecting heavy rain again this week and there is still snow in the higher elevations of the winny watershed. My beach is already eroding. Its a good thing that boat traffic is virtually nil. We could easily hit 505 by the end of the week - which should trigger a no-wake rule until the floods recede.

[NoRegrets]

I like the no wake time of the year. You can go out for hours and barely move the fuel needle!

I believe the last time we had a no wake condition it was posted "No Wake within 600 feet of shore". That was made interesting because many "bonehead" drivers had trouble with 150 ft and they still zipped by us at less than the 150 foot distance. No harm to us but it was wrong.

[robmac]

I remember it well.I was sitting talking to marine patrol about it while out in the Broads and there goes Captain Bonehead at about 60mph and the officer just shook his head and went off to educate him on what no wake means. And yes the fuel last quite awhile.

Lakegeezer I must correct you full lake is not "503.63" full lake is 504.32 feet above see level... just check the dam operation information on the DES website. As of tonight the lake is 504.53.... which is still with in the safety band the they publish of allowing the lake to fill to 504.80 feet during peak run off events.

I have been looking at a lot of the DES watershed data form many of the lakes and streams.... although there has been a significant amount of rain in a very short period of time which has cause many bodies of water to raise quickly. I have seen that all bodies of water have reacted and continue to react very quickly to the dam operations.

In short I don't believe we will spend very long with a full lake. As long as we can get a week or two of good warm weather the lake will come right down.

Thaks for the correction. I can't find where I got that wrong, but very precise number. I noticed they opened the dam even more overnight and it is flowing at 1862 CFS as of 4AM today.

Lakegeezer, no biggie just want to make sure no one got misled.... I wouldn't be surprised if statistically the average lake level for this time of year is supposed to be your figure of 503.63.... which I would think would be reasonable, as normally right about now is when the lake starts to fill up....and the ice melts. For what ever reason this year mother nature started things up early, and nothing match the statistical past.

[This'nThat]

Looking at the level for March 30, one thing is obvious -- the lake level has never been this high, this early in the year --- ever! (at least since 1982, when the lake level chart records began). And this doesn't include today's rain.

So, for everyone who's saying "the lake will recede quickly", I hope you're right -- but so far, history shows it will take 1 - 2 months for the lake to drop down to get back to "Full". That puts us at mid-late May, assuming no more real wet periods over that time. Wishful thinking? Or are we facing a different reality, which might involve "no wake" for quite a while?

If this is another mis-cue by those dam people ( )...
I'll get particularly irked.

I'm generally happy to own an acre of "near-to-nature" lakefront property.

However...

1) When the lake is over-filled, a great deal of forest duff gets "redistributed" along shallow shorelines.

(Once redistributed along the shoreline, some would call this mud—or silt).

2) These become the nutrients that promote algae—the snails that browse on the algae—and thence to the outbreaks of "Duck Itch".

3) With a no-wake rule invoked due to this mis-cue—though still pending—I'd expect that folks living around Lake Winnipesaukee's bays and coves will experience a growth rate increase of milfoil.

4) It's a much-bigger "deal" than having to discipline the speed of over-sized boats—temporarily.

IMHO

However, if anyone has any control beyond Mother Nature Herself, I trust the dam operator's. They do an exceptional job, and there is more than enough weather involved here for them to work with.

I really wouldn't worry to much about it.
