Rusto, I think the crayfish you are finding around the house just might be these ....

jim100, the burrow always has water or the crayfish has to move. The prairie types tend to occupy areas with an underlying hardpan. The top soils have a lot of clay but are permeable enough to support a very slow flow. Because of this, a water table of sorts lies above the hardpan after being saturated. As the table slowly dissipates, they dig deeper to stay in water. They are as you said, amazing creatures.
