- Critics claim that the dams, such as the Glen Canyon Dam, were built without taking into consideration their social, environmental and economic benefits.
- The timber dam is rarely used by humans because of its short lifespan and the limitation in height to which it can be built.

- A diversionary dam is a structure designed to divert all or a portion of the flow of a river from its natural course.
- Rock can be placed at steeper angles than soil, and it weighs more; so a dam built mostly of rock can be smaller in design section.
