It was advertised as a “waterfront getaway,” a tranquil campground spanning 65 acres along the shaded banks of the Guadalupe River. But a week after floodwaters surged over the riverbanks, all that remains of the HTR TX Hill Country R.V. Park & Campground are a barren expanse of dirt and gravel and the haunting outlines of foundations where “deluxe” cabins once stood.

The property, on the border of Kerrville and Ingram in Central Texas, all but vanished in the violence of the Independence Day flooding. Entire cabins were ripped off their foundations. As they lurched downstream, the owner of a neighboring R.V. park watched in horror while people trapped inside screamed for help.

The half-mile stretch of land occupied by the two campgrounds appears to have been one of the deadliest sites along the 250-mile river during the flash flood, with at least 28 people confirmed dead or declared missing, according to interviews, local news reports and social media posts.

Other zones of devastation in the predawn hours of July 4 have drawn more attention, notably Camp Mystic, a summer camp further upriver where 27 campers and staff members have been reported dead and six are still missing.

The company that owns the campground, HTR, has not said publicly how many people were missing from its property after the flood.
