    How much water can I drain?

    I have an inground plaster pool. Can I drain 2/3 of the water without issue?

    Where is the groundwater level (water table)? My first concern would be floating/cracking the pool.

    Are there ponds or creeks around? Is your pool on flat land or on top of a hill?

    No ponds, maybe a small creek about 10 houses down. The house behind me is a lot lower than mine is. Pretty flat in front of my house.

    One way to check is to dig a hole near the pool, as deep as your pool is. See if it fills with water overnight. If so, you may have a problem.
