This 2010 status and trends report about lake water quality in New Zealand updates the 2006 report ‘A snapshot of lake water quality in New Zealand’.
The report provides a national picture of current status (2005–2009) and trends in water quality of New Zealand lakes. It uses Trophic Level Index (TLI) and LakeSPI (submerged plant indicators) to provide a picture of nutrient levels and overall ecological condition, and discusses the results in the context of different lake types and land uses. In addition, a comparison of New Zealand lake water quality with a subset of lakes in Europe, USA and Canada is made.
