You can use the Scenario Builder for Lakes WebApp to:
visualise the current state of water quality (nitrogen and phosphorus concentrations, phytoplankton biomass and visual clarity) in all lakes in New Zealand. In unmonitored lakes, the current state is based on modelled information.
see the composition of land use in the lake’s catchment and the estimated relative contribution of different land uses in the catchment to contaminant loads entering the lake
model catchment management scenarios of land mitigation or land use change (or combinations of both) to predict how reducing contaminant losses from existing land use and/or changing land use within the catchment will affect water quality in that lake
