Yes the property slopes from the house down to creek.
I meant to say the house sits on a high spot. The back half or property is as low as surrounding area.
2 pits are still open and we're continuing to fill as of sunset.

Creek is small. Maybe 3 to 4 foot wide normally and 5 foot below grade with a water depth between a few inches in dry season and a foot or less on average rest of year.
