What if we do a little math. One surface acre equates to 27000 gallons of water. So if a tree consumes 100 gallons daily, then it will take 270 trees to lower the water level one inch per day That's a rough estimate, as different species of trees consume varying amounts of water, but it's ballpark.
So, by my calculations that means each tree that consumes 100 gallons will lower the water level in that 1 acre pond by .0037", per day. A sheet of notebook paper is often listed as .003"
I'm not cutting any trees just yet.
