2011 Lillooet River Survey – Cross Section and Bathymetric Survey

In August 2010, a massive landslide occurred on Capricorn and Meager Creek, a tributary of the Lillooet River. It was important that baseline Lillooet river conditions be documented before sediment from the Capricorn Creek landslide moves into the Pemberton Valley Dyking District (PVDD) service area. 

In 2000, there were approximately 60 cross-sections surveyed on the Lillooet River. Surveys were also conducted on its tributaries. Although the 2000 cross-section survey was comprehensive, a number of significant events have occurred in the intervening decade, including:

  • a major flood in 2003; and
  • several smaller landslides within the watershed.

Therefore, an updated survey provides a more representative ‘baseline’ for comparison with potential future sedimentation. This 2011 Lillooet River survey is intended to act as a baseline survey prior to the arrival of the majority of the sediment generated during the 2010 slide as well provide an updated river survey for comparison to previous surveys, and future modelling, analysis and design purposes.
