WOW!!
Over a 3 foot rise in just 4 days. It boggles my brain to imagine the volume of rainwater/inflow required to raise the level that much on a lake as big as Martin.

OMG- I have just checked the water level and am so amazed since last weekend - good thing our shore is clean and docks secured. Imagine it will be muddy - with the water rising so fast in many areas.

This is just the wet part of the drought brought on by global warming and it will take 10 years to fill up the lake. So send a check to Zimbabwe for their cap & trade credits.

If my conversion factors and calculations are correct:
The area of one acre is defined as 66 by 660 feet then the volume of an acre-foot is exactly 43560 cubic feet. Alternatively, this is approximately 325,851.4 U.S. gallons. (http://en.wikipedia.org/wiki/Acre-foot)
Lake Martin encompasses 39,180 acres.
With this, 325,851 x 3 = 977,553 gallons per acre of surface area 3 feet deep.
977,553 x 39,180 acres = 38,300,526,540 gallons for the recent three-foot rise.
Maybe there is an engineer among us that can confirm, or correct this.

Your math is spot on (a perfectly squared acre equals 208.71032557111303591192697393256 x 208.71032557111303591192697393256 feet, which is the same number of square feet as your 66 x 660 feet)
Bottom line would still be the same (We in the trade of dealing with water calculations round off the volume of 1 cubic foot of H2O to 7.5 gallons; more accurately 7.48 gallons)
Still a massive volume of water.

That amount of water would weigh a staggering 317,894,370,282 pounds.

Maybe somewhere in the neighborhood of 390 billion gallons.
39180 acres = 61 sq mi
3 feet rise = 0.00057 cu mi and 11 trillion gal/cu mi
130 billion a day
lot of water!
