  2. Grahamstown Dam was constructed between 1955 and 1965 as the Hunter’s third water supply source and is the Hunter’s largest storage of drinking water.

  3. Grahamstown Moors • The dam was formed by building an embankment across the outlet of a natural depression known as the Grahamstown Moors.

  4. Before the Dam • The land around Grahamstown before the dam was swamp land and there were some dairy farms. • The area was surrounded by water. Rivers flowed past and encircling the town of Raymond Terrace were lagoons and ponds. • The settlers who lived on the land were happy because it was easy to find water.

  5. Continued … • But their opinion started to change and they were saying that swamps were inferior land and they should get compensation. • They said the land was undesirable, unhealthy and unproductive. • A settler by the name of Richard Windeyer tried to drain the water out so they could make the land a better place to live, but it didn’t work.

  6. Continued . . . • Instead the land was left the way it was as dairy farms and swamp land. • Until … more and more people moved into the Hunter region. • The water board needed to find another place to store water for all of the new people who were moving into the area. • In 1948 they decided to use the Grahamstown area to help increase the water supply to so many people. They were set to build a new dam on the site.

  7. Continued . . . • It would be bigger than the other dams that they were using at the time. • In 1955 construction began on the dam and it continued until 1965. • In 1960, however, there was a drought and some of the water that had been stored had to be used before the dam was finished to help give water to the people in the Hunter.

  8. Continued . . . • Today there is not a lot of swamp lands left, however we can see some swampy areas around here today.

  9. The End • The land has been built up and there have been many houses constructed in this area. • When it rains the ground gets very damp and waterlogged. It takes a long time to dry. • In summer we have lots and lots of mosquitoes. And mosquitoes are found in swamp lands. So even though man has changed the environment around us today to make it a better place for us to live, the natural environment is very much present, too.

  10. Grahamstown Dam Today • Discharge Channel • Grahamstown Dam serves the water supply needs of Newcastle and the greater Hunter region of New South Wales. With a current capacity of 131 000 megalitres, it is the largest above ground storage facility owned and managed by Hunter Water.During the 01/02 financial year, Hunter Water continued work that will ultimately increase the capacity of the dam to 195 000 megalitres. As part of this programme, Hunter Water commissioned BMD Major Projects Pty Ltd to undertake construction of the Grahamstown Dam Discharge Channel.
