A major flood emergency unfolded in Doña Ana County in southern New Mexico after intense rainfall caused serious flooding and raised concerns about the stability of McLeod Dam, also known locally as Garfield Dam. Authorities initially warned that the dam faced a potential failure and ordered residents in nearby communities to evacuate to safer areas.
The National Weather Service issued an urgent flash flood warning after officials reported that McLeod Dam was in danger of failing. Residents in areas potentially affected by water released from the dam were urged to move to higher ground immediately and avoid waiting for conditions to deteriorate.
The communities initially placed under evacuation orders included Salem, Garfield and Rincon. Authorities later expanded evacuation instructions to other areas, including Hatch and Placitas, as flooding conditions developed across northern Doña Ana County.
McLeod Dam is located northwest of Hatch and is also referred to as the Garfield Dam. According to reporting from the Albuquerque Journal, county officials warned residents that the structure was showing signs of being overwhelmed following heavy rainfall. People in the affected communities were advised to take essential medicines, identification documents, important belongings and necessary supplies before leaving their homes.
Residents were also asked to take care of children and pets and to use safe evacuation routes. Officials recommended Interstate 25 as the main evacuation route where possible and warned people not to travel through flooded roads or low water crossings.
Emergency shelters were established to assist people who had to leave their homes. One of the designated locations was the Radium Springs Community Resource Center, while another shelter was made available at the Doña Ana Community Resource Center in Las Cruces. The American Red Cross was also involved in providing assistance to evacuated residents.
The situation was made more complicated by flooding in surrounding areas. Near Rincon, an arroyo breached levees close to the Rincon Water Treatment Plant, prompting a separate evacuation order. Authorities warned that floodwater could threaten structures in the community and instructed residents to leave immediately.
The flooding was associated with a broader weather system affecting the southwestern United States. The remnants of Hurricane Polo brought heavy rainfall across parts of New Mexico and neighbouring states, increasing the risk of flash flooding in areas where the ground was already saturated.
The National Weather Service warned that the combination of intense rainfall and runoff could create dangerous conditions in southern New Mexico. Officials repeatedly urged residents to follow emergency alerts and evacuation instructions and to avoid driving through flooded roads.
The initial reports regarding McLeod Dam described the situation as potentially life threatening. The National Weather Service warned of the possibility of an imminent dam failure and urged people in low lying areas below the dam to seek higher ground.
However, the situation later changed. Doña Ana County subsequently announced that evacuation orders for Salem, Garfield, Hatch and Placitas had been lifted. The evacuation order for Rincon remained in effect in the latest update cited by local authorities. Residents returning to areas where orders had been lifted were warned to remain cautious because flooding, debris, damaged roads and other hazards could still be present.
The change in evacuation status does not mean that all flood-related risks had disappeared. Authorities continued to advise residents to monitor official emergency information and avoid areas affected by standing or moving water.
Floodwater can remain dangerous even after rainfall decreases because water levels can rise rapidly in rivers, arroyos and drainage channels. Roads can also be damaged or blocked by debris, making travel hazardous.
Local authorities also used a staged evacuation approach to prepare communities for changing conditions. Residents were advised to have essential items ready, monitor emergency alerts and be prepared to leave immediately if conditions worsened.
Schools in the Hatch Valley area were also affected by the flooding. Some schools were released early and some bus routes were changed because of roads that became difficult or impossible to use.
The emergency response involved county officials, emergency management agencies, weather authorities and humanitarian organisations. Emergency personnel worked to provide evacuation information, operate shelters and assess the condition of roads and flood control infrastructure.
Reports also noted that McLeod Dam had previously been classified as having a high potential hazard classification. A report by KRWG, citing the National Inventory of Dams, said the dam's last inspection in 2023 had described its condition as poor. The report also said the dam did not have an emergency action plan listed in the inventory at that time.
Officials were closely monitoring the dam and surrounding flood control infrastructure as heavy rainfall continued. The focus remained on protecting residents in areas that could be affected by additional flooding or infrastructure failures.
The incident demonstrates the challenges faced by communities in southern New Mexico during periods of extreme rainfall. Areas that normally receive relatively little rainfall can experience rapid and dangerous flooding when intense storms move through the region.
Residents in affected parts of Doña Ana County were urged to follow official evacuation instructions rather than relying on unverified information circulating online. Emergency officials also advised people not to cross barricades or attempt to drive through floodwater.
As of the latest reported update, evacuation orders had been lifted in Salem, Garfield, Hatch and Placitas, while Rincon remained under an evacuation order. Authorities continued to warn that flooding, debris and road damage could create hazards even in locations where evacuation restrictions had been removed.
The situation remains weather dependent, and further rainfall could change local conditions quickly. Residents are therefore being advised to continue monitoring official announcements from Doña Ana County, the National Weather Service and local emergency authorities.
