Mangahao release for Saturday 10 September in doubt February 11th, 2020 2005-09-06T14:46:00+12:00 [09:23] Access Officer Graeme McIntyre advises that the scheduled release from Mangahao’s Dam No 2 on Saturday 10 September is doubtful due to lack of recent rain. Unless we get heavy rain before Friday 9th it is unlikely that this release will go ahead. We will endeavour to provide notification of cancellation on this site. Update 14:46: Release is cancelled due to low water. Proposed replacement release is 1 October 2005.
