If the contractor is still running the RV FHU campsites, then they will still be running the pay showers and laundry.
The hardest hit location due to the drought is the Panther Junction HQ area where the only water well was going dry in 2014, then the Castolon housing and Cottonwood campground, where the well water has to be heavily treated before it is usable.

The Chisos Basin gets its water from springs below The Window, though the water has to be pumped about four miles in a 6 inch pipe uphill 3,600 ft to a 20,000 gal tank above the Lodge.
There is a lengthy environmental story behind why over 2/3 of the natural springs at Big Bend have disappeared in the past 140 years, and avoiding the lost of most of the rest is impossible.
