At that time it was well understood that rainfall would likely increase in intensity over the next few decades. That would have been the perfect time to have done a proper job of bringing the dam into the 21st century and rebuilt it to modern specs with plenty of headroom. But typical (austerity) government thinking was to just patch it up for the next decade or two. Kick the can down the road so it's someone else's problem. Maybe this time they will pull it down and do a proper job. Or do you reckon they just patch it up again?
