Watercare says a majority of the heavy rain in the last couple of days in Auckland has been soaked up by dry ground, rather than running off into the storage lakes, RNZ reports. Water levels on dams increased by less than one percent overnight to 57.85 percent, which is still far below the historical average of 80.88 percent for this time of year. Manager of improvement programmes, Anin Nama, said the city has had a long dry period and will need more rain in order for the ground to get saturated first. Water will then run off into the dams, which would be expected to respond better following consistent rain.
