Very Good point, I never investigated water shed issues, since I
believe I do not live in one.


There are two definitions of "watershed" in the US; one of them
is the area that drains into a specific body of water, (usually
a river). The other is wrong. But the word is used as a synonym
for "divide", as in "the Great Divide", which (again, in the US)
names the border between the pacific watershed and the atlantic.

If your house is build on the ground, you live on a watershed.
