PHOENIX (KSAZ/AP) -- Officials with the Tohono O'odham Nation announced late Tuesday night that they are preparing an emergency evacuation of areas around the Menagers Dam community, due to concerns over the dam's integrity.
In a statement, tribal officials say residents of the Menagers Dam area need to move as far to the north end of the community as possible, due to rising floodwaters and uncertainty over the integrity of the dam. Officials said rainfall from the remnants of Rosa has produced "unprecedented" levels of flooding in the area.
The National Weather Service on Wednesday said water levels were within 1 foot of overtopping Menagers Dam and that it could give way and flood the community of Ali Chuk on the Tohono O'odham Nation's reservation west of Tucson.
In addition, the Tohono O'odham Nation officials said they are evacuating more than 30 members of the Kohatk village. The village, located in Pinal County, is located about 74 miles south of downtown Phoenix. Officials said water in an adjacent wash is running extremely high, and continues to overflow the berms to flood the community.
The Arizona Daily Star reported that the community has a U.S. Census-reported population of 162 and that the area got between 3 to 5 inches of rain on Monday.
