CLEAR LAKE – After more than two days of searching dive teams have not been able to find a young Windsor man who went missing in the water of Clear Lake Saturday afternoon.

Matthew Zanoni, 22, was riding on a pontoon boat with friends in the area of Shag Rock off Buckingham Saturday shortly before 3 p.m. when officials say he either jumped or fell into the water and didn't surface. Shag Rock is a rocky outcropping that rises out of the lake; it is located east of Clear Lake State Park and close to the Narrows.

Lt. Cecil Brown of the Lake County Sheriff's Office said the North Shore Dive Team and Lake County Search and Rescue Dive Team continued their search throughout the day on Monday.

“They didn't do a recovery today,” Brown said.

Brown said the search effort also used sidescan sonar, a technology similar to that rescuers used to locate the body of Vacaville resident John Stockton, who went missing in the lake in May.

The sonar system, which Brown said can scan in all directions, was brought in by a private contractor.

Brown said divers held a debriefing Monday on the day's search, with plans to continue Tuesday. He said rescuers have been communicating with Zanoni's family as the search has continued.

Divers are very limited in how long they can stay in the water because of various factors, particularly the water conditions, Brown explained.

Brown said on Monday evening the dive teams were discussing how to proceed in Tuesday's search effort. He did not have information available on what outside agencies may be assisting the search.

Zanoni was in Lake County visiting BoardStock, according to a family friend who contacted Lake County News.
