I'll preface this by saying that we are drenched. Snow, rain, ice, etc etc.
So I went under the house today to run a piece of coax for a tv.
I found around the trench around the foundation, about 6 inches of water.

What's everyone's opinion on whether or not this is a problem?

Normal with this type of weather?

It doesn't have water standing all the time. I've been under this house god knows a hundred times in 7 years and only one other time was there water, and that was neglible compared to this.
