This dashboard shows information on the data collected by the regional councils and unitary authorities for two indicators of lake water quality and ecological condition: TLI (Trophic Level Index) and LakeSPI (Lake Submerged Plant Indicators). Select an indicator to see the historical results.

Water Quality
Trophic Level Index (TLI)
{{rating() | uppercase}}
{{comment()}}This measure is the Trophic Level Index (TLI). The TLI indicates the life supporting capacity of a lake and is based on four water quality indicators.
Show more information Hide informationTrophic Level Index (TLI) history for this lake
Trophic Level Indicator (TLI) which measures four parameters: water clarity, chlorophyll content, total phosphorus and total nitrogen. From these parameters a TLI value is calculated. In cases where water clarity data is missing a three parameter TLI is calculated. The higher the value, the greater the nutrients and fertility of the water which encourages growth, including algal blooms. As a rule, higher TLI scores mean poorer water quality.

Ecological Conditions
Lake Submerged Plant Indicators (LakeSPI)
{{rating() | uppercase}}
{{comment()}}The LakeSPI status describes the ecological condition of the lake and is based on plants present.
Show more information Hide informationLakeSPI history for this lake
LakeSPI (Lake Submerged Plant Indicators) is a method of characterising the ecological condition of lakes based on the composition of native and invasive plants growing in them. A higher LakeSPI percentage result is associated with better ecological health:
LakeSPI N/A LakeSPI {{spiData.details.Value}}% The overall LakeSPI score is calculated using a Native Condition Index ('good' plants) and an Invasive Impact Index (introduced, non-native plants):
Native Condition N/A Native Condition {{spiData.details.NativeIndex}}% Invasive Impact N/A Invasive Impact {{spiData.details.InvasiveIndex}}% NA A higher Native Condition value indicates better ecological condition, but a higher Invasive Impact value indicates invasive plants are negatively impacting native plant communities.
