No. Even the campground hosts had a huge water tank they were taking down the hill to fill.

There is no potable water — last we were there, 2021. Water and dumping are available just north of Gardiner and north of the road to turn on to climb into this campground at the Sinclair Station. Wonderful campground, right near Yellowstone’s north entrance. Don’t know the condition for access to Gardiner, the campground, or Yellowstone after last year’s flooding.
