Lake Level

[Formula260SS]

Can anyone tell me the effect all the rain and run off has on the lake, does the ice raise and lower (it must in my opinion) and what effect does it have on the shoreline, current ice surface and such.

I would think with all the weather this year we are looking at some interesting conditions now and come spring. Here's to somehow avoiding a spring flood situation !

It looks like the lake level is dropping right down. It's pretty low in anticipation of the big melt down.

Formula,

Here is a link to a chart that lets you know the current level of the lake, together with a historical view of the past 30 year average. It also shows what is coming in and going out.

Notice the big inflow increase during the last few days and the reduction of outflow due to the lowered release at the dam to help things down stream.

We have a thread about spring flood potential in the weather section... check that out. The 'short & sweet' answer is that we have a snowpack deeper than we've had in many years and it contains 2.5 times the normal amount of water our snowpack should have at this time of year. The snow has been equally deep downstream (i.e. Concord) and even deeper upstream (the mountains.) The last rain storm we had dumped over an inch of rain into the snow (which is still 30 inches deep) and most of it has frozen instead of running off. So, the conclusion is: "We're waiting to see what happens."

As for the ice, my guess is that it would rise with the water and become somewhat loose within the newly expanded shores, which could speed its seasonal demise.

This year's flood threat is for rivers as well as lakes. Emergency management officials in NH and Maine are much more concerned about the rivers. The effects of "high lake" don't mean a whole lot in the grand scheme of things if we can't even drive to or around the lake because the roads have been washed out by rivers for the second or third time in 3 years.

The runoff is now creating havok with the roads as the ground is beginning to soften underneath. The winter frost heaves are coupling with potholes... too much speed on some of the area's roads might put you in the shop for an alignment or even a new front tire.
