As part of the Kemano II Environmental Study, Environment Canada, Fisheries Service, initiated a program during 1974-75 to inventory existing water chemistry, plankton and benthic fauna of Morice Lake. The main objectives of this study were to provide data to determine the present trophic state of the lake, the nutrient loading into the lake, phytoplankton and zooplankton biomass and lake benthic fauna population. These data are used to assess the total lake productivity and to predict responses to an altered environment.
