Why Tides Do not Occur on Lakes or Other Bodies of Water

All the seas and oceans around the world are connected. Water can freely flow between them. That’s the reason tide can occur on them.

On the other hand, lakes are isolated from one to another. Water cannot freely flow between them. That is the reason tide in meaningful amount cannot occur on lakes or any other bodies of water.

When a location on the sea has high tide, the volume of water increases and this additional volume is supplied from another area where a low tide occurs. In other words, water flows from locations having low tide to another having high tide.

In lakes, this cannot happen. Even though the Moon exerts the same amount of gravitational force, there’s no way the additional volume of water can be supplied to cause a high tide.

The same thing happens to other bodies of water., including rivers, ponds, pools, etc. Tide cannot occur because water cannot flow freely from or to another location having the opposing tide.

Tides do occur on lakes, but with a much smaller scale. The tides in the Great Lakes is less than 5 cm. Consequently, the Great Lakes are considered non-tidal.

Flat-Earthers often consider the lack of tides in lakes as “a failure of modern science to explain the nature” or something like that. In reality, there is no such problem. Science can sufficiently explain tides. It is just they don’t understand them.
