On November 1st, 2018 the Big Bar Landslide temporarily blocked the Fraser River, the most productive salmon-bearing watershed in Canada. Salmon are iconic animals on the west coast of North America, a critical element of Indigenous culture and an important commercial and recreational fishery in British Columbia. The landslide initiated one of the largest and most expensive emergency river restoration projects in the history of Canada. The Landslide Impact on Flow Dynamics, Fish Migration and Genetics of Fraser River Salmon project team used geospatial data, observations of flow dynamics, and radio telemetry to track salmon migration across the hydraulic barrier formed by the Big Bar Landslide to explore the impact of the landslide on channel morphology, flow dynamics, and salmon migration.

This collection is an archive of the data used to examine the Big Bar Landslide, investigate the potential for future landslides elsewhere in the Fraser Canyon Corridor, and to explore the dynamics of other potential hydraulic barriers to salmon migration in the Fraser River. This Archive is maintained by the River Dynamics Laboratory & Jeremy Venditti.
