I have a 15x30 above ground that has been up maybe 7 or 8 years. We have had lots of rain this season, more than normal. My pool went up maybe 3-4 inches in the last rain this week. I noticed tonight with the light on that there appears to be what looks like a maybe 2" wide raised tunnel running from a foot in the pool for maybe 10 feet. There are trees nearby but this is like a perfect tunnel, I put the brush over it and it seems firm. Could this be groundwater? I didn't notice this when vacuuming last week, but the light shows everything at night. I did notice I got a lot more wrinkles in the liner I never had. I was going to try to close this weekend but now I am concerned if the trees may be an issue or if I am overreacting since I did not notice before. The tunnel does not start near the edge. Then I noticed a second one in a different spot but not as long.
Any thoughts/suggestions, could it be the water table. My soil is like a sandy/clay where the pool is. I do have a crack in my basement floor that will seep water once in a while and they told me that was the water table rising at one point and the crack was caused by hydro-static pressure or something, it has since been sealed. The basement is lower than the pool.
