Activities are tailored to suit each unique reservoir reserve and help you explore the different surrounds these beautiful places have to offer. See what each reservoir reserve has to offer:

Many of our reservoirs supply drinking water to South Australians and the water level in each can change during the year depending on rainfall and seasonal demand for water.

Blue-green algae

Algae is a common occurrence in open water sources, including reservoirs and the River Murray, especially during warmer months of the year when conditions are favourable for growth.

SA Water samplers, operators and scientists actively monitor and test the source water and connecting water networks during these times and adjust treatment processes as needed. This ensures they continue to supply safe, clean drinking water to their customers.

Some blue-green algae species produce compounds which can be harmful to humans and animals. Contact with untreated water in a reservoir where algae are present can be harmful to your health.

When blue-green algae levels are increasing, and related water treatment or algal management activities are being conducted, the site will be closed to visitors until 1pm that day. There will be clear signage at the entrance and on this website page.

To find out more, read SA Health’s information about blue-green algae health impacts and how to avoid illness.

You can learn more about how SA Water manages reservoirs and other water sources on their website.

Forestry SA plantations

Forestry SA plantations are at a number of reservoir reserves including Myponga, Mount Bold, Happy Valley, Warren and South Para (See Forestry SA's map of plantations in the Mount Lofty Ranges). These plantations are managed by Forestry SA in a four step cycle:

  1. establishment - the planning process ahead of seedlings being planted
  2. planting - when seedlings reach about nine months old, they are planted
  3. harvest - plantations are 'thinned' every 10 years and at about 40 years, the remaining trees are clear-felled, enabling the site to be re-established
  4. wood products - harvested logs are used for a variety of products.

More information about this process is available on Forestry SA's website.
