Small lake is a 20-cell still life. It is similar in structure to lake 2, although it is not a true lake itself due to its four sides that are only a single cell in length.

In other rules

It occurs frequently in the Life-like cellular automaton B3/S235e, evolving from several precedessors of traffic lights. It is also common in Life variants with S4n.
