Vidal Valley forms the large border of the south side of the east-west block of the Whipple Mountains massif, the landform that forces the Colorado to flow southeast, then back southwest.

The Colorado River Aqueduct crosses the midpoint of the valley at Vidal Junction, California.

The Vidal Valley also lies due east of the Danby Dry Lake landform.

Both watersheds enter the Parker Valley, mostly occupied by the Colorado River Indian Reservation.

As desert washes, typically little or no water flows at the outfall points into the Colorado River, except during rainstorm events.
