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 occur naturally in reservoirs and occasionally algal blooms can be present in reservoirs. This is more likely in the warmer months of the year, and they are not always visible.

Regular testing is undertaken as part of SA Water’s routine water quality monitoring. During a blue-green algal bloom, water treatment is adjusted to ensure the continued supply of safe, clean drinking water for customers.

Some blue-green algae produce toxins which can be harmful to humans and animals. Contact with the untreated water in the reservoir when high levels of blue-green algae are present can be harmful to your health.

When blue-green algae levels are extreme, reservoirs are closed to all activities that involve contact with the water, including fishing and kayaking/canoeing.

Signage on site will be updated and specific access and closure details are available on each reservoir page on this site.

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.
