Quitobaquito Springs in south‑west Arizona is an oasis fed by an aquifer and lies within Organ Pipe Cactus National Monument. The spring supports the Sonoyta pupfish, springsnails, and the Sonoyta mud turtle, which are the only wild populations of these species. The area provides the only reliable water source within about 100 miles and has cultural significance for the O’odham people.

In 2020 a 30‑foot border wall segment was completed nearby, during which spring flow fell to a record low and the pond partially dried. Plans now call for a second 30‑foot steel wall segment 90 to 150 feet north of the existing structure, a distance that includes part of the pond and a mesquite grove identified as critical habitat for the mud turtle.

The Department of Homeland Security has waived several environmental statutes, including the Endangered Species Act and the National Environmental Policy Act, under the 2005 Real ID Act, allowing construction without the usual consultations. CBP said it will not pump within five miles of the springs, but hydrologists note that the aquifer feeding the spring may extend beyond that radius. Researchers such as Michael Bogan of the University of Arizona and Tara Harris of the Phoenix Zoo warned that the project could eliminate the remaining habitat for the mud turtle and other imperiled species. The Phoenix Zoo and the Arizona‑Sonoran Desert Museum have offered to house up to 50 turtles and several groups of springsnails in temporary facilities, though officials stressed that relocation is not a long‑term solution. Indigenous leaders, including Wynona Larson Yazzie of the O’odham community, described the proposed construction as “sickening” and said it could destroy a cemetery containing more than 40 graves and damage a 1,000‑year‑old intaglio earthwork.

CBP declined to answer further questions, and contractors have been observed surveying the site, suggesting work may begin soon. The road that provides the primary vehicle access to the spring could be closed as early as next week, potentially extending travel times for residents and visitors. The situation remains unresolved as federal officials continue to assess the environmental impact and as the agency prepares to execute the wall construction.
