Ewen Maddock Dam Water Supply Protection Program​

Supporting healthy land practices to maintain safe drinking water quality in the Ewen Maddock Catchment.

Supporting sustainable land practices to maintain safe drinking water quality in the Ewen Maddock Dam Catchment.



Mooloolah River Landcare has partnered with Seqwater to deliver financial and technical support to prioritise activities to maintain safe water quality within the Ewen Maddock Dam Catchment area (see map). Though it is a small catchment area of 21km2, the Ewen Maddock Catchment is the sole source of drinking water for Caloundra, as well as being a popular recreational spot for locals to enjoy swimming, fishing and kayaking. Addlington Creek is the main tributary of Ewen Maddock, which flows from the top of Dularcha National Park, down through Landsborough town and into the dam. The key stressors on our water quality are sediment, nutrient and pathogens through urban stormwater runoff and small-scale farming.


The aim of the Water Supply Protection Program is to bring local landholders and experts together to both improve the function and health of their land while protecting the quality of water to sustain safe water supply. Our program is a collaborative effort between us and you, the landholder. We can provide funding for activities on your property including, but not limited to:

  • Revegetation along waterways
  • Revegetation of eroded areas
  • Management of ‘transformer’ weeds – Madeira, Cat’s Claw and Chinese Celtis
  • Erosion repair on dirt roads and driveways
  • Land management advice
  • Installation of fencing along waterways  


This program provides a number of personal, environmental and community benefits, including:

  • Financial incentives for projects
  • Planning support and advice
  • Healthy land and improved function of your property
  • Improved water quality in Ewen Maddock Dam and its creek-lines through Landsborough
  • Safe drinking water for Caloundra
  • Increased native flora and fauna on your land and surrounds
  • Increased resilience to climate extremes and large weather events
  • Connection to local landholders and community through community events and workshops
  • Reducing bank erosion along our waterways
  • Improving habitat health within our catchment



Eligibility for this program is determined by a number of factors, including:

  • Your property location and environmental issues you are facing
  • Evidence of transformer weeds
  • Willingness to actively participate in projects, providing in-kind contributions through financial, labour or other.

If you aren’t sure if this is you, we may still be able to help. As a Landcare we can assist in finding other forms of funding that you may be eligible under.

Transformer Weeds

 These three weeds have been prioritised under this program as transformer weeds as they have the capacity to transform riparian ecosystems. Madeira and Cat’s Claw are vigorous, fast growing vines that have the capacity to smother whole ecosystems and bring down canopy if left unmanaged. Chinese Celtis is a weedy tree that is semi-deciduous, dropping large amounts of leaf litter, as well as being a proliferous seeder. Celtis has the capacity to overrun whole ecosystems fast.

Madeira vine - Anredera cordifolia
Celtis sinensis
Chinese Celtis - Celtis sinensis
Cat's Claw vine - Dolichandra unguis-cati
