The report is based on monthly physico-chemical and microbiological water quality records collected for a surface water quality investigation in the Waihopai catchment, completing Phase One of Environment Southlandgass gbsLiving Streamsgcs programme. The objectives of Phase One were to determine the state of water quality in the Waihopai catchment and identify links between land use, non-point source pollution, and water quality. The water quality in the Waihopai catchment is indicative of a highly modified lowland catchment with intensive agriculture in the headwaters, with lifestyle, community inputs at various points, and urban pressures in the lower reaches. Consequently, identifying patterns in water quality was complicated due to the diversity of land use within the catchment, along with a lack of investigation into drain and stormwater inputs. The broad scale of the monitoring programme (12 sites spread throughout a large catchment) also provided limited spatial resolution in the sampling results. However, even given the difficulty in isolating sources of poor water quality within the catchment, patterns have been identified with respect to faecal contamination, nutrients and sediment that deserve more detailed assessment. - Executive summary
