Join the National Capital Authority (NCA) and Greening Australia this October for community planting days of aquatic macrophytes (water plants) in Lake Burley Griffin.

NCA Acting Chief Executive, Andrew Smith said macrophyte plantings are one of the initiatives being implemented to improve the water quality of Lake Burley Griffin.

'Following the successful trial conducted last year in partnership with Greening Australia we now know which plants are suited to our conditions.' Mr Smith said.

'Aquatic macrophytes act as filters and can help trap sediments, pollutants and organic material and prevent these from entering the water. They improve oxygen levels and reduce the levels of phosphorus and nitrogen in the water.'

'This is all good news for improving the water quality in Lake Burley Griffin,' he said.

Volunteers are being sought for the community planting days which will be held from 9.30am to 11.30am at Yarralumla Beach on 6 October 2013, Lotus Bay on 13 October and West Basin on 20 October.?

A free BBQ will be provided after each planting. Register by contacting Greening Australia on 6253 3035 or email by the Thursday before each planting day.

Everyday tips to help protect our waterways

Small but effective measures will help reduce the levels of nutrients in catchment areas and help improve the water quality of Lake Burley Griffin.  These include:

  • Keep gutters clean and ensure garden waste and lawn clippings are raked up, to prevent them being washed down drains after rain
  • Prevent soil from entering stormwater drains during heavy rain
  • Check that sewers and drains are in good repair and not blocked. Report any suspected sewer leaks to ACTEW Water by calling 6248 3111
  • Wash cars on grass and reduce the amount of water used, or use a commercial car-wash that recycles water to ensure soapy water doesn't flow into the stormwater drain.
