More rain for Melbourne catchments

To support its conservation strategies, MMBW is working with the CSIRO in an attempt to augment water supplies by increasing rainfall in the main Thomson River catchment area in Gippsland by an expected 10-20 per cent through cloud seeding. Originally, seeding added silver iodide to clouds in an attempt to stimulate them to release at least some of the rain they contained. Now, however, CSIRO researchers are adding silver iodide to clouds that are already about to release rain in an attempt to make them release more - to improve the clouds' efficiency as producers of rain.
