A man is believed drowned at Lake Shasta after never resurfacing. At around 9:30AM Monday morning a man near the O’Brien Inlet entered the water after his houseboat became untethered from the bank. After going underwater, he was not seen again. Shasta County Sheriff’s Personnel, including the dive team, responded along with Cal-Fire. The search continued into the afternoon, but very high winds and the sharp drop in depth greatly complicated efforts to find the man. Crews will try again Tuesday morning.
