The level is 481.73 at 7:40am and rising!

That's approximately a 1.3 foot rise in the last 24 hours.. Pretty amazing, considering it takes 1,916,000,000 (round that off to 1.92 billion) cubic feet to raise the lake level 1 foot... Still have a ways to go, but we are back on the curve and 1 1/2 feet above last year...

Huske. the relationship between lake level and water volume is not linear but curvilinear. The rise in Martin pool elevation from 480.7 to 481.7 equates closer to 14.8 million cubic feet according the lake's water storage capacity curve for the difference in volume between those two pool elevations.

Oops. The difference is 1.48 billion cubic feet of water for one foot pool rise from 480.7 to 481.7ft.

As a former math major in college, (took me twice to get chrough calculus 2) and 25 years of oxygen depletion from flying jets for USAF (among other things), I accept your calculations.. I just took 44k (lake acreage) x 44k (approximate # of sq ft/acre) to get about 1.9B cubic foot/foot of elavation.. .. KISS principal at work... good bit of water however you pour it... But it's looking good, another 2 feet and the boat house will be back in operation..

Great KISS work! A good, crude analogy is using a funnel (or cone) and computing volumetric changes related to changes in vertical height. Fur sur its crude, but if you slice the cone in half vertically and lay it on its side and scale it accordingly, you kinda get closer to visualizing volume/water storage changes in reservoirs with related to changes in pool level. 5th grade math is all you need.

Forget the math! If we get a few more widespread rains that come down like a "domesticus bovinus urinating upon a metamorphic outcropping", the lake will be full pool.

Volumetrics.. jeeze, gives me a headache.. But get the concept.. kinda like if you p in a coke bottle it fills fast... in a gallon bucket it takes longer??? Still need a lot of billion of cubic of feet the fill the lake, but driving across Sandy Creek gives me optimism.. Warm regards to all..

as of 2:55pm on the Alabama Power site.....Best we've seen since before the 4th of July.

I knew a good engineer from API had the right answer! Let's just hope they're no bovine pies in the offering too.

All the math is fascinating, but what excites me is that my ramp is in the water now!!

482.45 as of 6:00am Sunday.. up 0.8" in the last 24hrs.. guess I need to break out the chest waders now to replace pcv in the lakebed for my irrigation system.. to be expected if you are thinking too much about math during the winter and forget to drain the system.. regards

Lake Level shows higher on this site by a couple of inches , than the Alabama Power Site. They show 482.52..Just curious where this site gets its
numbers.? I've become addicted to checking the levels during the day!
This is so heartening!

sorry.. meant alabama power shows higher. I guess they update more often?
|
The APC site updates all day and is usually accurate within a few minutes. This site updates daily.

Okay. 483 for sure by dawn Monday! (Unless Martin dam squirts before then which is not scheduled and not likely.)
