Thanks Tums. I completely get it.
I still want to hear your 165 mm rainfall place story. It must be interesting. If there isn't a creek around, it is impossible, isn't it ? Actually your story might be a great lesson for me. In my city , 600 mm rain and 1200 mm evaporation. How bad is that you think? Can i survive just with well and city water?
The 165 mm area (near Bakersfield, CA in 1990) was educational related about learning ways of collecting, holding, and distributing water for irrigation purposes.
You are saying that In your area you Basically get near 2 feet of rain per year and lose near 4 feet to evaporation. On a 1/2 acre lake that means you will need a minimum of ruffly 326,000 US gallons of well water to make up the difference of the evaporation to rain ratios alone. Here we can not use city water because of the chemicals in the water will cause a fish kill. SO be careful about using city water. You will also need to know if your water table in the area will be able to support that much well usage. Remember also that you useing a well alot can cause shallower nearby wells to run out of water. I personally own a well that pumps over 630,000 US gallons per day. The other unknows is how much more water are you going to need to cover for other ways of loss like, Seepage, animals usage, vegatation usage. ect.... One thing I have learned in my days as that nearly anything is possible with enough means. In the end you are going to have to decide is having the 1/2 acre pond worth what it will it will take you to have it. I imagine there is several pond owners on here that have ponds that recieve near the same amount of annual rainfall that you do. Hopefully some of them will see this and post some helpful information from there personal experience,
