The Merri Creek turned a muddy brown colour after heavy rain in early January and many people have been asking 'why?'

The mud appears to be from headwater areas, north of Donnybrook , where parts of the Merri and its tributaries flow through light coloured sedimentary rock (rather than basalt typical of most of the catchment). Possibly, heavy rain eroded the creek banks or washed dirt in from a development site.

Merri Creek Management Committee reported the problem to the EPA who continue to investigate.
