250,000 gallon recreational pond project

Thought it was interesting to watch the progress so I decided to share it. I love the color of the water with a natural bluish tint but this is an attribute to the natural water aquifers in the area. I have a few functional criticisms regarding the design. For one it may collect runoff water carrying nutrients which is fine but I like the idea of maintaining a clear water pond. Erosion from the steep slope is another functional criticism but again it is manageable as well as the vicinity of the trees which will contribute to the organic matter over time from falling leaves.

That's nice!

Never could get water that clear here with this red Georgia dirt.

Did the YouTube poster give that gallon figure ? Square footage or acreage would make more sense unless the plan is to suck it dry for irrigation. Most people have some concept as to the area of their house or apartment. I doubt that one in a thousand know how many gallons it would hold if filled with water. ( Just to illustrate that absurdity, a 1000 sq ft condo with 8 foot ceilings would hold 59,840 gallons of water if the tub were left running for far too long. The pond holds 4 condos worth of water) ----------------------------------------------------------------------------------------------------------------------------------------
So here it is. There are 7.48 US gallons in a cubic foot of water. 250,000 divided by 7.48 = 33422.459893 I'm going to forget everything after the decimal.

Suppose the pond averages 5 feet deep. 33442 divided by 5 = 6684.4 or about 0.15 of an acre

If it averages 10 feet deep then it's about 3342 sq. ft.

-----------------------------------------------------------------------------------------------------------------------------------------
One more for good measure --- The average adult drinks about 275 gallons of water per year. It would take a guy 909 years to drink that much water.
-----------------------------------------------------------------------------------------------------------------------------------------
As you can see, I passed grade four math and I therefore have some concept as to the size of that pond. There's 10 minutes that I'll never get back.

The average adult drinks 275 gallons of water a day?

WOW, I can barely choke down a quart a day on my good days!

Oops, per year. Slight difference. At that rate you could drink it all in under 3 years ---- and you'd never get anything done with all the pissing.

Same problem here brother, we got the Piedmont orange clay! What I plan to do is seal the pond with Carolina clay, put a liner, then a rock/gravel layer and top it off with white silica sand. I found a quarry near by towards the coast and I will have to dump a few thousand dollars. You can find wholesalers using http://www.thomasnet.com/ by searching for stone of silica sand (the beach stuff).

Yeah, I think on his second or third video but he calculated 500,000 gallons. That looked too liberal a calculation so I guestimated to about half of his original estimate at 250,000 gallons.
