Two kayakers made a gruesome discovery while out on the waters of San Francisco's Lake Merced on Saturday: a decomposing body, face down in the north end of the lake.

According to KTVU, a kayaking instructor and his student were paddling through the north end of Lake Merced at around 2:48 p.m. Friday when they saw a body caught in the reeds.

San Francisco Fire Department Battalion Chief Kevin Smith told KTVU that it took two SFFD divers to drag the body across the lake to Harding Park, where they then removed the deceased from the water.

KPIX reports that it's believed that the body is male. However, the San Francisco Medical Examiner couldn't confirm gender, age, or any other details to SFist at publication time, saying the deceased had yet to be identified.

The cause of death also remains unclear, the Medical Examiner's office said today.

Lake Merced has long been known as a place where bodies tend to appear, as a 1910 San Francisco Call story illustrates. Most recently, a missing Daly City man was found in its waters, and kayakers found another body in the eastern reeds in 2009.
