LakeSPI (pronounced "Lake Spy") uses Submerged Plant Indicators (SPI) for assessing the ecological condition of New Zealand lakes.

The underlying principle of LakeSPI is that any New Zealand lake can be characterised by the composition of native and invasive plants growing in the lake and the depth to which they grow.
Once key submerged plant indicators have been identified and recorded using the LakeSPI survey method, LakeSPI applies a simple scoring system to generate 3 LakeSPI indices (or scores):
By using submerged plants as indicators, the effects of water quality, and the impacts of catchment management and aquatic weed invasion can be assessed. This is just one of the many uses of LakeSPI.
