Land Air and Water Aotearoa (LAWA) uses the Trophic Level Index (TLI) to monitor water quality in New Zealand. This measures four parameters: water clarity, chlorophyll content, total phosphorus and total nitrogen creating a final score. Over the last 10 years water in Lake Dunstan has scored between 2.1 and 2.8. These scores fall between ‘good’ and ‘fair’ [1,2].
‘Good’ is classified as oligotrophic lake conditions. Oligotrophic lakes are found to have high oxygen content and low organic content meaning algae and other organisms are rare. ‘Fair’ is where the lake is mesotrophic, meaning water is average due to moderate levels of nutrients and algae

Only 1% of the Great Lakes' water passes via the St. Lawrence River each year, which is an intriguing statistic about the lakes. The contaminants that are discharged into the Great Lakes stay there and over time grow concentrated since the Great Lakes are virtually a closed system. Additionally, a sizable number of contaminants are making large-scale contributions to the Great Lakes.
