Tasmania weather: Hydro report finds cloud seeding had no effect on Derwent Valley flooding
29th July 2016
A report by Hydro Tasmania has found a cloud seeding operation carried out in June did not increase rainfall in the hours before major flooding.
Cloud seeding is a technique used to increase rain to bolster dams and involves the addition of a substance to suitable clouds to encourage the growth of ice crystals or raindrops.
There were no flood warnings for the targeted catchment areas at the time of the cloud seeding flight, but concerns were raised about why Hydro tried to boost rainfall less than 24 hours before expected statewide flooding.
But a report released on Friday found the cloud seeding operation was redundant, because the cloud was already precipitating freely.
Hydro had brought forward the start of its cloud seeding season this year as part of efforts to rebuild storages after an unprecedented dry spring and summer.
Hydro Tasmania will review its cloud seeding program, including in relation to seeding when there is flood risk.
