2.2. Dams are classified according to whether they belong to the class of high-capacity dams, low-capacity dams or small dams.

The following dams are considered to be high-capacity dams:

(1)  dams 1 metre or more in height having an impounding capacity greater than 1,000,000 m3; and

(2)  dams 2.5 metres or more in height having an impounding capacity greater than 30,000 m3.

Dams 2 metres or more in height to which the second paragraph does not apply are considered to be low-capacity dams.

Dams 1 metre or more in height to which the second and third paragraphs do not apply are considered to be small dams.

If there are two or more dams on the rim of a single reservoir, all of them belong to the most restrictive class applicable to one of them.
