Sediment cores were taken from the central and western basins of Fraser Lake during October 1999 using a modified K-B corer (internal diameter ~6.35 cm). The cores were subsampled for diatoms and 210Pb analyses. Results suggest that the lake has always been mesotrophic. Changes in inferred rates of sedimentation combined with lower amounts of organic matter suggest that watershed activities may have caused unusual rates of sedimentation in the post-1950 period; however, it does not appear that these changes have caused changes in diatom assemblages, and indirectly water quality, that are unusual for this lake.
