I don't know why it's so clear and blue. One of my back hoe diggers said he thinks I hit a spring. The pond is ~100' away from the headwaters of Muddy Creek which eventually feeds into Lake Ray Hubbard. My inlet is rainwater runoff, but in high water conditions, something could swim upstream. Is there a reasonable way to control this?

Here's a pic of my first water samples. I had to tell the kids not to drink them they were so clear. "Almost" the same clarity as tap water. The PH was 7.4, but I don't remember the other numbers. Higher in Calcium which I assume comes from the limestone. So maybe the color is coming from the limestone?
