Thank you for the response. Many people in our neighborhood do have above ground pools and although most of the yards appear to be the same level, we have had a definite problem with our back yard staying very soggy, especially the back maybe 8-10 feet of the yard to the back fence. When my husband replaced the fence last year, his holes for the posts were filling in with water as he dug. We're not sure why this is but our yard definitely seems wetter than most others around here.

So, in your opinion, if we created a circle of mulch to put the pool on, that should prevent the pool from sinking unevenly? Would mulch be better than dirt of some sort? I'm so afraid that once we start filling the pool with water that it will sink unevenly into the soft ground and therefore not be level. The mulch should prevent that?
