The Pecos is a stream that arises in northern New Mexico on the eastern slope of the Sangre de Christo mountains. It flows 925 miles south into Texas where it joins the Rio Grande. Over appropriated and poorly managed, it is the subject of the Pecos River Compact between New Mexico and Texas. During the drought of the 2010s irrigators with senior water rights near Carlsbad on the lower reaches of the river in New Mexico failed to receive adequate water for their crops and threatened a call. Due to a long history of inadequate management, even threatening a call was highly disruptive as there seemed to be no way to deliver water to the lower river without producing a major disruption on the upper river near Roswell.
