Carterton's worst-kept secret has been confirmed in a two-year study by the Greater Wellington Regional Council.
Decades of sewage dumping and farm run-off has meant the further you paddle down the Mangatarere Stream the murkier and slimier it gets.
The regional council's environment monitoring and investigations manager, Ted Taylor, said that when the river was low during the summer people would be swimming among green and brown algae growth.
''It rates as one of the worst streams in terms of water quality and that's why we did this investigation, not just to say whether it was high or low, we wanted to know what the quality was like along the whole stream.''
The stream had some of the highest nutrient readings in Wellington, with high nitrogen downstream from farms and high phosphorus downstream from Carterton's sewage treatment plant.
Carterton District Council chief executive Colin Wright said the regional council had already banned dumping into the river during the summer and now people increasingly wanted to dump on land instead.
''No discharge to the river could be 20 years away but what we are trying to do is take steps in that direction,'' he said.
The council has added charges to industrial waste dumping and is happy the district's biggest business and nutrient dumper, Premier Bacon, is addressing its waste.
''They are currently spending a large amount of money introducing a defrosting arrangement, letting a tonne of blood less go down the sewers,'' he said.
Regulating farm run-off is the domain of the regional council, which says it is reviewing its regional plan and would consider increased plantings.
