A recovery effort is underway after a man fell into a canal in Alameda County this weekend and has not been located, the sheriff's office said Sunday night.
Just before 10 p.m. on Friday, deputies were alerted to a possible drowning at the Delta-Mendota Canal under Grant Line Road. A group fishing in the area said that a man fell into the canal and got swept away by the rapid current.
The man, identified as 56-year-old Hollister resident Lester Ashcraft, reportedly slipped from a steep embankment and the group he was with attempted to rescue him, but he could not stay afloat in the fast current.
In an effort to find Ashcraft, the San Luis and Delta-Mendota Water Authority slowed the canal's current from 3,500 cubic feet per second to 900 cubic feet per second, the sheriff's office said, but the current was still unsafe for divers to enter.
Despite searches by air, unmanned aerial vehicles (UAVs), and on foot, the multi-agency effort to locate Ashcraft was unsuccessful, said the sheriff's office on social media Sunday night.
Rescue crews also conducted an additional search again on Saturday but could not locate him.
As of Sunday, the recovery of Ashcraft will be "dictated by the current," the sheriff's office said.
