1.3 x 10^15 gallons which is 1,300,000,000,000,000 gallons
One on-line resource says that the area of Lake Lanier is 57.92square miles, and that it's 160-ft deep. Using those figures, the volume is 1,932 billion gallons. (rounded) Y…ou have to be careful with that number. In addition to some water,part of the volume is undoubtedly occupied by mud, fish, suburbanlawn-fertilizer run-off, discarded tires, a sunken bass boat or two, several lost golfballs, and frogs. The number is a reliable ballpark order-of-magnitude bulletproofguesstimate.
Approximately 8,146,286 gallons of water.
This reservoir has a capacity of 74,970 acre feet (92,438,010 mÂ³ or 24,439,049,470 Gallons).
Water volume 2.9 km3 (2,400,000 acreÂ·ft)
Google states that the volume of Lake Michigan is about 1,180 cubic miles which equals 1,299,318,234,000,000 gallons [US, liquid]
It is impossible to accurately answer how many gallons of water arein a lake. The depth constantly varies, as do the levels. However,based on averages, a rough estimate can be… given. Lake Okoboji hasa surface area of 3,847 acres and an average depth of 39 feet.There are (rounded) 325,851 gallons of water to an acre foot, orone acre covered in one foot of water. Based on the size andaverage depth of the lake, there would be somewhere in the hugeneighborhood of 48,888,403,083 gallons of water in Lake Okoboji.
To answer this, a couple of assumtions are made. The average depth is 4.3m, and the surface area is 4400 kmÂ². Assuming these numbers are static (which they are NOT due to r…ainfall and heat evaporation), and ignoring the fact that the shoreline changes with depth of the water, the computation follows. 4.4(6) * 4.3 = 18.92(6) cubic metres 1 gallon = 3.78l 1 litre = .001 cubic metre 18.92(6) cu. metre = 18.92(9) litres 18.92(9) litres equals just a hair over 5 billion gallons, close enough that the rounding to 2 sigfigs wipes it out. ------- Sorry, I am not as versed in metric, but the answer is actually 5 trillion (not billion) gallons. Wikipedia gives the volume as 18.92 cubic kilometers, which is 4.5 cubic miles. A cubic mile contains 1.1 trillion gallons, which would make the volume of 4.5 cubic miles about 5 trillion gallons. Wikipedia also gives the volume as 15.3 million acre-feet. 15.3 million x 43,560 square feet in an acre = 666 billion cubic feet. 1 cubic foot of water = 8.1 gallons. 666 billion cubic feet x 8.1 gallons = 5.4 trillion gallons. Caveats regarding the changing volume of the lake due to weather conditions apply. ------- I indeed make a mistake. The conversion from 4400 kmÂ² to mÂ² was inaccurate. It is 4.4(9) instead of 4.4(6). This makes the final answer 18.92(12) which does come to 4.998 trillion gallons.
Approx 756,993,907,779 gallons
It is impossible to know for it changes every second. With tributaries (rivers) and the water shed, humans, and fish mass. There is no likely guess.
Well the 5 great lakes contains 6,522,286,740,000,000 gallons of water in total
My guess is about 3 trillion. Just a mathematical estimate
1 acre = 43,560 square feet 1 cubic foot = 1,728 cubic inches 1 gallon = 231 cubic inches Volume of the lake = (1.5 x 43,560) x (5) = 326,700 cubic feet = 2,443,885.7 … gallons (rounded)
