Greetings.

I live in a developed suburban community (at the apex of the area
grade) and I'm having some trouble with water in my basement. I've
installed excursion drains and directed water away from my home but
have a question; how does one determine the water table on a parcel of
land?

My house is 150 yrs old - is this the kind of record that's kept by
municipal gov't?

Many thks, in advance, for advice...
