BAKERSFIELD, Calif. — Despite several search efforts, The Kern County Sheriff's Office said it has yet to locate the missing 11-year-old girl that was swept away by the Kern River in June.

Officials said the flow of the river, at the time, was approximately 4,000 cubic feet per second and Kern Valley Search and Rescue crews spent hours trying to recover her body but yielded efforts after "river flows remained unseasonably high."

Following their initial search efforts, between June 22 and November 1, KCSO said volunteers spent more than 3,000 man-hours on various searches along the river.

"Even though some of the search efforts extended several miles to the Delonegha Bridge area, most of the searching was concentrated on the first six miles downstream from where the juvenile went missing," KCSO said. "The decision to focus specifically on this area was based upon the experiences of past searches similar to this one."

KCSO said when the river flow became more reasonable officials organized a final effort to locate the body but that was also unsuccessful.
