STA PROCESS: Collect samples and identify sediment types

  • 1,027 sediment grab samples were collected for the STA. Sample spacing was 500 m.
  • Geophysical techniques were used in screening the lake to allow a grab sample to be taken safely.
  • Seven sediment types were found on the bottom of Lac Saint Pierre.  Note that there are no relationships between the sediment types and the flow of the river as might be expected.
