Grand Tank is a reservoir located near White Tank campgound. From reports I've read, it apparently holds water after any significant amount of rain in the area. I've visited several times over the years, but have never found water behind the dam wall. With all the rain the park received during the last half of January, I thought, "what the heck, I'll go check it out. Maybe there'll be water there this time."

Cattle ranchers are most likely responsible for building the dam that creates Grand Tank. The dam is a tall, narrow structure built between two large rock formations that "pinch" together, effectively damming the wash in which it was built. There is a large area behind the dam, with numerous valley and washes that drain down through this spot.

The following images show how Grand Tank usually looks. Bone dry.
