Rescue crews were unable to find a man who may have drowned in Lopez Lake on Thursday, according to Cal Fire spokesman Chris Elms.
Authorities responded to a 911 call at 2:20 p.m. after a boat flipped over with three people inside. Elms said he did not know how the boat flipped.
All three boaters began swimming toward the shore, Elms said, and two of them were wearing life jackets. The man who was not wearing a life jacket “was having a hard time” swimming back to shore, went under the water, and was not seen again.
Elms said 10 rescue swimmers, a CHP H-70 helicopter, San Luis Obispo County sheriff’s deputies and Cal Fire assisted with the search.
The search was called off about 4:20 p.m., and the investigation was turned over to the San Luis Obispo County Sheriff’s Office for “further search/recovery,” according to a Cal Fire SLO tweet.
