Aquatic A collection of interacting living and non-living things. A More help to maintain clean water. Plants in and beside rivers, wetlands and lakes act as filters, cleaning the water by intercepting and taking up water pollutants. This especially important for nutrients, such as nitrogen and phosphorus, which can be damaging for waterways in large amounts. Microbes (tiny organisms such as bacteria) that live in the soil and water recycle nutrients by decomposing dead plant and animal matter so that plants can use the nutrients again.
Because water flows through the environment, when water quality or quantity is put at risk in one area, it is likely that other places will also be affected.

ACT’s aquatic ecosystems
The ACT has five main rivers and An area of land on which rain falls, this land then helps to More areas: the Cotter River, the Gudgenby River, the Molonglo River, the Murrumbidgee River and the Queanbeyan River. Canberra has three constructed lakes – Lake Burley Griffin, Lake Ginninderra and Lake Tuggeranong – along with numerous other constructed ponds and wetlands.
There are at least 12 important wetlands, along with the internationally recognised and protected site, Ginini Flats. High A bounded geographical area, distinct from one another.

The Murrumbidgee River is important, both environmentally and culturally. In local Aboriginal language, Murrumbidgee means ‘big water’. It is the largest river in the ACT, the second-longest river in Australia, and it feeds wetlands, swamps and floodplains in the ACT and NSW. The Murrumbidgee supports much life, including plants and animals for agriculture, native plants and many animal and fish species. Some fish species, such as the Murray cod, live their whole life in the river. Bird species, such as the sharp-tailed sandpiper, breed in Siberia and then migrate every year to the wetlands of the Murrumbidgee. All the ACT’s rivers and creeks eventually flow into the Murrumbidgee. So, scientists can use the river as a reference to assess the overall aquatic health and water quality of the ACT area.
