Where I live, we don't have lakes, per se, but resevoirs where a valley is dammed up, and the water is let out periodically for irrigation. The walls of the resevoir get ridges like that when the water sits for a while (the waves lap at the shore, eating it away) and then they let out water, and the water level drops. Once they stop letting out water, it starts eating away at the shore again. The longer the water sits at a level, the larger the 'cliff' becomes.
