To obtain better historical information on nutrient loading to Osoyoos Lake, sediment cores were collected from the north and south basins of Osoyoos Lake in June 2008. 210Pb dating was used to develop a chronology for the cores, and to estimate rates of sediment accumulation. Changes in algal pigment concentrations and diatom communities, as preserved in the cores, were used to infer changes in algal production and Total Phosphorus (TP) concentrations since European settlement.
