Project Description: The purpose of the 2005 Aquatic Effects Monitoring Program is to initiate a long-term aquatics sampling program in order to produce a data set that will be used in trend analyses to track the overall effects of the project on the aquatic ecosystem of Lac de Gras and to confirm predictions made during the Environmental Assessment. This is achieved by conducting consistent annual sampling at fixed mid-field and far-field stations for which baseline conditions have already been established. Eleven fixed stations will be visited by boat. At each station, water samples will be collected at mid-depth for full chemical analyses including major ions, trace metals, and nutrients using the lowest commercially available analytical detection limits. At each station, samples will also be collected for zooplankton and phytoplankton biomass. Samples for taxonomy will be archived. At three separate stations, samples will be collected for benthic analyses and sediment chemistry. Sampling will not create any environmental hazards. The study will be conducted at Lac de Gras
