Why Dam?Australia is a very dry continent. Because of this there is a need tostore water.In order to create storage reservoirs, a dam is built across rivers to store fresh water forus to use. When a river is dammed, its flow is restricted and therefore the surrounding landis flooded. This has a negative impact on the natural environment and its wildlife. The alsoaffects the flow of water downstream, which can cause siltation or other forms ofmurkiness, which result from a drop of environment flows.But dams are a major factor in providing a controlled water supply to our local region. Lookat a map of your local area and identify where local dams, channels, weirs and barrages aresituated. Search and report why these were constructed at the particular locations and whatpurpose they provide. Also include what sort of negative impact that’s been seen because ofthese man made structures.16
