Can you get waves in a lake?

Waves on lakes are mostly the result of wind and are called “wind-driven” or “surface” waves. Sure, we suppose a random earthquake could trigger a whitecap or a lake could be big enough for the moon's gravity to pull a little water back and forth but, almost always, the waves you see on lakes are being created by wind.

The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape.

During the early morning hours, the land and the water start out at roughly the same temperature. On a calm morning, a given pressure surface will be at the same height above both the land and water. A few hours later, the sun's energy begins to warm the land more rapidly than the water.

Lake Superior is notorious for dangerous waves of a different kind: clusters of rogue waves. These abnormally large waves are colloquially known as “the three sisters” because they appear to travel as a trio, the second and third wave swamping a ship before it recovers from the first battering.

The stress of wind moving over the lake surface causes a transport of water within the lake, as well as the movement of energy downwind through the mechanism of surface waves. The wind is therefore one of the most important external forces on a lake.

Exorheic, or open lakes drain into a river, or other body of water that ultimately drains into the ocean. Endorheic basins fall into the category of endorheic or closed lakes, wherein waters do not drain into the ocean, but are reduced by evaporation, and/or drain into the ground.

There is reduced visibility: Swimming in low light or after dark can be dangerous, especially if you're in an ocean, river or lake.

Lake temperatures are largely driven by interactions with the atmosphere, so colder air temperatures lead to colder lake temperatures, according to the NOAA Great Lakes Environmental Research Laboratory (GLERL).
