REC210-0743

Seqwater should, in creating the new Wivenhoe and North Pine flood mitigation manuals, comprehensively consider: • the amount of discretion that is able to be exercised by the flood engineers and the senior flood engineers, and the description of the circumstances in which such discretion may be exercised • the circumstances in which it might be appropriate to release water in advance of an impending flood on the basis of forecasts from the Bureau of Meteorology • if strategies of the form of strategy W2 and W3 in Revision 7 are included in the revised manual, or any strategy defined as a ‘transition strategy’, when and how those strategies should be implemented • if the concept of ‘urban inundation’ is relevant to the operation of the dam, how it should be defined, and if the definition involves diverse concepts, how those concepts can be related back to the strategies, so that flood engineers can reach a clear understanding of their objectives and primary considerations • if the concept of ‘natural peak flow’ is relevant, how it should be defined.
