Search and recovery efforts for four men missing after a weekend boating accident on Folsom lake are being scaled down.

Diving teams have been searching the lake since Saturday.

"Using SONOR, using robotics, cadaver dogs, locate the missing men.  Unfortunately the searches have turned up nothing today," said Vicky Waters.

Waters, with the Parks and Recreation Department, says efforts will now be limited to daily patrols.    

"We also have a CHP helicopter on call to aid in those searches and we will continue to search the lake for the four missing men," she explained.

Toby and James Strauch, Jake Jacobs and Jon Smith are said to have been jetting down the Lake at speeds of more than 100 miles an hour when their boat capsized Saturday afternoon.
