Dry conditions in South Taranaki caused by the current La Nina weather pattern could mean further restrictions on how much water can be taken from rivers, Taranaki Regional Council has warned. The environmental watchdog is keeping a close eye on rainfall levels, soil moisture, river flows and climate across the region, with most of the Council’s monitoring sites recording less rain than usual over the last three months. Council data for the lowest rainfall sites shows Pātea recorded 61% of
river beds. As of last week, five of the seven monitored river sites and one lake were unsuitable for swimming (for humans or dogs) due to cyanobacteria (toxic algae). We will continue to monitor these sites until they return to normal, posting the results on LAWA each week. We’ll do a full analysis of the summer’s results, but most of the samples that exceeded guideline levels were taken after heavy or prolonged rain. We know heavy rain washes contaminants off the land into rivers and out to sea.
