Water Demon

The Water Demon was an evil demon composed entirely of water, with the power of hydrokinesis. It kills by drowning its victims from the inside out with it's watery body. It would also kill innocents by possessing the body of a victim it had already drowned and then have the dead body drag victims into the lake to drown. It surfaced and tended to attack at Lake Skylark near San Francisco, where the Halliwell family vacationed. When attacking a victim out of water, it appeared to take on an actual embodied shape.

Late 1970s
In the late 1970s, it killed several children at Camp Skylark. Local witch Patty Halliwell investigated it, as her children had attended the camp. She, with the help of her whitelighter Sam Wilder, figured out a way to vanquish the Water demon using electricity clamps at the side of the lake. Unfortunately, as Patty was about to implement her plan, Sam tried to stop her (she had told him to stay away from the lake previously). Whilst she was distracted by freezing Sam, the demon shot out from the water behind her. She tried to freeze it, but it was immune, thus it entered her, and drowned her from the inside on the dock by the lake.

2000
In 2000, Patty's daughters, The Charmed Ones planned to vanquish the demon after it had killed two more adults there. ("P3 H2O"), including the girls' old camp leader. Phoebe had a premonition of her mother trying to kill the demon and how it killed her. Thus, the girls decided to use Patty Haliwell's plan using the electricity clamps. Prue decided to do so as Piper would be in more risk, because her freezing power would not work on the demon, like Patty's didn't. When the demon arose to confront Prue, it tried to trick her also by rising up behind her.

However, Sam jumped in front of Prue and attempted to kill it by attacking it with high voltage electrical cables; zapping it with this electricity, he was successful in destroying the demon, but he died in the process.
