Can you get pulled under in a lake?

Dispelling the Myth of the Rip Rip currents do not pull people under the water; they pull people away from shore. The rip current is typically the strongest about a foot off of the bottom, which can cause your feet to be knocked out from under you making it feel like something under the water was pulling you.

Can there be an undertow in a lake?

You may have heard about the rip tide or undertow before. These are terms that people commonly use to describe dangerous currents.

Can lakes have rogue waves?
