The basement is periodically flooded during rain storms. Sometimes twice a year.

There is a swamp right behind our house (60' from the basement). Swamp Elevation is 185'.
The swamp is fed by spring fed pond (850' x 150'), 200 feet away @ eleva 185'.
There is a small stream about 125' from the basement. (Pond over-flow).
Many times there is running water in much of the swamp.

Elevation near the house is 191 feet. Our basement floor elevation is about 184'.

So, the water table is very close to my basement floor.
A lot of rain means my house will try to float.. (But it leaks).

Even without rain, you can sometimes see a darkening of the floor and it feels slightly damp.

The humidity in the living space isn't a problem.
Sometimes during cold weather, it gets pretty dry. We have a humidifier.
This past winter was so dry, we never needed to use it.

It's 122F in the attic right now, the ceilings of the living area are at 76.2F.
Room temp is 75.7F and 90F outdoors. (Sanyos lofting along).

It's dry up here, but pretty humid downstairs. The A7 is helping a little.
Maybe when it gets colder and the A7 runs longer, it will be drier down there.

We've been living with a damp basement for 39 years, so I'm not going to spend a lot of time worrying about it.
But, I would like to pump some cheap heat down there during the winter..
