Heavy Rainfall Triggers Flooding in Hopi Communities, State of Emergency

Amid relentless downpours and intense thunderstorms, northern Arizona’s Hopi communities are grappling with significant flooding challenges. This week, the deluge has impacted numerous villages, leading to a substantial emergency response effort.

The flooding, as reported by local authorities, has wreaked havoc across the Hopi reservation, affecting Lower Moenkopi, Upper Moenkopi, Hotevilla, Bacavi, Old Oraibi, and several other communities. The damage spans from infrastructure to homes, highlighting the severity of the situation.

In response to the crisis, Coconino County officials swiftly delivered 20,000 sandbags to Lower Moenkopi. This action followed a request from local leaders to manage the overflow of Moenkopi Wash, a tributary of the Little Colorado River. Lower Moenkopi is strategically located at the northwestern edge of the reservation, nestled between state highways 160 and 264.




Crews offload sandbags to help with the overflowing Moenkopi Wash on the Hopi reservation during the week of Oct. 19, 2026 following several days of heavy rainfall that triggered flash flooding across the region.

The National Weather Service has indicated that when water levels hit 27 feet, homes and crops in Lower Moenkopi begin to face flooding threats. On Thursday, the U.S. Geological Survey/NWS gauge recorded a water level of 33.92 feet at Moenkopi Wash, significantly surpassing the 29-foot major flood stage by nearly 4.9 feet.

Hopi leaders declared a state of emergency on Thursday, citing the persistent rainfall and subsequent flash floods that have severely disrupted roads, bridges, utilities, and other critical infrastructure. The flooding has also instigated rock slides, raising concerns about public health, safety, and disrupting essential services.

The emergency declaration has activated various tribal agencies, including Hopi medical services, law enforcement, and the Department of Natural Resources, to assist in managing the crisis. This directive will remain effective until November 6.
