Drownings are a common occurrence at the 80-mile-long All-American Canal, which transports water from the Colorado River to the Imperial Valley and runs parallel to the U.S.-Mexico border along several miles. Deep and steep along the sides, it’s quite easy to fall into, especially at night. Many of the canal's victims are immigrants traveling along the Calexico border.
