Yes. Never put your tent in a depression. That is a good one for the words of wisdom thread. I got my first tent in 1984 or something for $30. A three person dome by who knows who. Zipped on down to Punta Baja (in Baja California) to do some graduate work. No excuses, we put this thing up, brand new, in a clay depression (no footprint by the way). The place is known for intense fog and fog drip, hence the desert in that area is pretty "green". I wake up in the morning, lay my arm down on the tent floor and it feels like I am in a water bed. I couldn't believe it. There was almost 2" of water in the depression, and the tent did not leak.
