Lake Level
 
I am often asked how low is the lake getting? I believe a "full pond" is 504. Ft, according to Home Page on this web, at Weirs Bridge. Could the lake level be posted here and tracked daily? Or is their an easy web site to view this on? Also I have calculated, for example, if the lake is at 503.72 it is down about 3-5/8".
There must be an easier chart to convert this. (I am not, nor do I pretend, to be a good mathematician!) I just find this interesting and a giant pain to figure out how low the lake is getting, or how much closer that rock is to my prop! Hey the Lake is down 3" the rocks are 3" higher! Just wondering and looking for simple.:):confused:

Go to:

bizer.com

On the left side of the page click "Lake Level".

On that page there is a graph, with historical graphs too. It's very convenient.

There you'll see that the lake is on the low side compared to the last few years, but not crazy low, more like typical August level.

You can also click through to the NH DES data for lake level.

I think everything you are asking for is there, hope that helps!

Lake Level Update
 
The lake level last weekend at East Bear Island was abut 5 inches down from full. 🐻

That sounds right. The lake level on Saturday was down 5" from "Full Lake."

I suspect it rose a little after last night!

Lake Level Bizer Chart
 
If 504.32 is full and the black line looks like it may be at 503.85. I would say lake is down (Down.32 +.15 = .47 of a foot which is maybe 5-1/2 ") Does that sound about right? Chart is difficult to read and I hope someone comes up with something more user friendly. Thank you.

The low point looking at DES website this past week was 503.78....full lake is 504.32 so here is the math:

.54 x 1.2 x 10 = 6.48 inches

.54 is the total difference from full lake
1.2 is the number of inches per tenth of lake level
10 is the multiplication factor to get back out to inches from 10ths

Guesstimate
 
Several years ago, my brother installed a pair of nails at full lake level on a dock post. This is our gauge and we eyeball the level from this data point. 🐻

Easy to read
 
Attach a piece of clear plastic tube to a dock post. Drop in a wire rod with adequate Styrofoam the bottom to float it up and down. Mark the lake levels on the dock post. Perhaps inches on one side, tenths of a foot on the other. I believe levels vary a smidge compared to Weirs Bridge. For example, If you measure in Wolfeboro, the lake may be higher due to large inflow from Back Bay that takes some time/space to dissipate. I've heard, as much as an inch. I guess that's minor if you're using your propeller to find the rock the OP was looking for. LOL

Lake level
 
If you take one foot (1.00 feet) and divide by 12 inches, you find each inch is 0.083 feet. (Figure .08 get for simplicity).

How far is the lake down at 503.78? Subtract 500.00 from 500.32 = .32 . It's another .22 to get to 503.78. .added together .54 ÷ .08 = 6 inches plus, or almost 7 inches.

I use this site https://www4.des.state.nh.us/rti_data/WEIN3_TABLE.HTML . Updates regularly during the day.

Oh Sure Dave, do the math differently then I did it....:laugh::laugh::laugh::laugh

However your way does give us a slightly more accurate number as you include the .007 of an inch my way leaves off....

Truth be known, I just used the "8" in my division. If I was off by one inch in my calculations, and it was that critical, either I shouldn't be going there, or even going out.

Enjoy L.I.

May I interject the "Materiality Principle" of accounting here, boating style:


1" too shallow? 2 BMU's

2" too shallow? 2.1 BMU's

The difference is immaterial.
