The Pemberton Valley Dyking District (PVDD) has updated its sediment management plan to account for the impact of the 2010 Mount Meager landslide, with the new plan calling for a significant increase in sediment removal.

"Since that slide, we hadn't had good updated information (on the) full scope of the impact," said Steve Flynn, operations manager at the PVDD. "Now we do understand it ... now we can deal with it."

Prepared by Northwest Hydraulic Consultants Ltd, The Lillooet River Flood Mitigation Program: Preliminary Sediment Management Plan says that sediment removal in the order of 210,000 to 260,000 cubic metres a year may be necessary over the next several decades.

It draws heavily from the Lillooet River Floodplain Mapping Report, which was released in December 2018 and found that peak discharge flows related to specific flood events are higher than previously understood and infrastructure does not offer as much protection as was previously thought.

The Meager landslide took place 66 kilometres upstream of Pemberton and caused some channel blockage of Meager Creek and the Lillooet River, but no major flood.
