As the title mentions I noticed a 3'x5' wet spot in my yard about 10-20 feet from the back of my pool a little over a month ago. I first noticed it about one month from the time my pool was filled. I've looked back through pictures and the spot was not wet in any pictures prior. My yard has a downward slope heading to a small pond about 20-30 yards away. My PB graded dirt from the elevated back beam of my pool down the slope. I have not sodded the yard yet since I was concerned about a possible leak.
Since the first time I saw the wet spot, my area has been hit by nonstop heavy rains and flooding so by the time the rest of the ground would start drying up for me to check the spot it would rain again. This past week has been the longest stretch of dry weather in over a month. I did a 24hr bucket test to check for a leak but water loss in the pool and bucket were exactly the same. I began to wonder if possibly the soil, which is largely clay, was just saturated and it would take a while to completely dry. After a week of dry weather, although smaller, the wet spot was still there. I decided to dig down to see what I found. I dug down about 1-1.5 foot which was the level of the prior lawn surface before adding the dirt and grading. The dirt and clay was very wet. After leaving the hole open for several hours, water began to pool about 1-2 inches deep in the bottom of the hole. To my knowledge, there are no water or sewer lines running in the area either. I'm assuming if they would have hit a water line during the dig they would have known that immediately? All my pool plumbing held pressure for over two months waiting for plaster. If I'm not showing a leak with the bucket test but there is obviously something keeping this spot wet, what should I do next?
