I'm a first time owner, 15' x 30' x 4' deep oval, above ground pool. How much water per day can I expect to lose to evaporation?

I do live in southwest Texas, very hot and dry this time of year. Seems to go down about a 1/4" per day right now.

I'd say around a 1/4" per day....

Or around 1/2 of 1/2 inch per day.

Maybe you should float a bunch of black ***** on it to cut down the evaporation.

Where I am it would be over flowing every day, lots of rain, the only thing that seems to evaporate up here is my Scotch bottle, cheer`s

Lmao!!! You guys are hilarious! I can always count on a laugh on dtr

Seriously though, I could calc the volume if I had a few more measurements but those oval bag pools are hard to figure unless you have a fill mark and a volume stated on the sticker...which is probably underneath it!

Engineers toolbox is a great site with all kinds of info for questions like that, maybe you could get an evap idea off of it?

Scotty

I was thinking measure the number of gallons you replace the first time with a meter on the hose.
The box or instructions might have the volume it holds too. If there's a fill line or height to stop at, you could get a close calc from that.

My fill line is a mark on the plastic skimmer housing inside the pool wall. I was told the skimmer works best with the water level at or above that mark. So that is my reference point when I said it seems to drop about a 1/4" a day right now when it's hot and dry.

Thanks!

I have a 16x30 5 deep inground indoor pool and the evaporation rate can be easily controlled by keeping the floating cover on when not in use. With the cover off during the summer with the room wide open it can easily drop 1 inch a day depending on the humidity level outside, with the cover on I can leave for a month and the pool not drop any. The few minutes it takes to remove and install the cover is well worth it.

Forgot to mention I used to cut the cover to fit inside the pool walls but the cover expands and contracts with temperature, I found some days in the winter the room could become quite humid with water evaporating from the small gap around the outside so what I do now is cut the cover larger so it comes up the inside wall of the pool about 3 to 4 inches all around, this cuts evaporation out almost completely.

If anybody is starting a pool, ha ha, I want the 13 gallons/day square....

I am also in south Texas (Houston area), and have a 20K in ground pool. It's a true "cement pond"

This past summer during that dry spell we had, I lost about 1" to 1¼" per week, which for my pool, 1" is roughly 350 gallons. My pool gets a lot of full sunlight during the day. Yours being an above ground pool, the evaporation losses will be different.

Ideal water level is about halfway up the opening for the skimmer. Freezing is not much of an issue down here, I kept our pool open all year, and didn't winterize at all. Wasn't worried about the pipes freezing when it dropped into the 30's. Temps have to drop into the 20's for an extended period of time for PVC pipes to start freezing.

If you want to learn more about pool care (especially the chemistry), cruise on over to troublefreepool.com . It's the DTR equivalent website for pools I joined there last year when we bought our house. The knowledge gained has saved a lot of money on pool chemicals, the water quality is excellent and crystal clear all the time, and it's fairly easy to take care of when done right.

Hope this helps

Uh, I meant the 130 gallon square.....

Maybe this is old, but...place a can of water next to your pool. Fill it and measure how deep it is. Measure it each evening. The water will evaporate at the same rate. Just do the math for the container size difference

Evaporate, or have some critters drink out of it.....
