Dams buddy writing

Dams  block the flow of water. Dams are built across the river or stream.

The purposes of dams are used for retaining water and used for fishing .

Also dams are used to generate electricity. Waitakere operates fourteen supply reservoirs.
Five of them are in the Waitakere Ranges.

Dams supply 80 percent of Auckland’s water. Early dams were made out of earth and rock.
After World War Two dams were built of earth and rock.

Dams need 1.8 metres of rain in Auckland annually a year .
