Posted on November 09, 2016

High Streamflow Advisory: Lillooet River (Downgraded)

ISSUED: November 10, 2016 12:00 PM

The BC River Forecast Centre is downgrading to a High Streamflow Advisory for:

  • Lillooet River near Pemberton, and surrounding creeks and tributaries

Dry conditions over the past 24 hours have resulted in decreasing flows in the Howe Sound region overnight. Flows are expected to continue to drop through the day as dry conditions persist until late tonight.

Due to the high runoff volumes on Wednesday, residue backwater conditions may be prevalent near Pemberton and Squamish and on Lillooet Lake. These conditions are expected to slowly subside through the day, with high lake levels persisting overnight.

Another storm event is forecast to arrive tonight. Rainfall rates are expected to be approximately 1 mm/hr during the event. Total rainfall in the Pemberton area from Thursday night to Saturday evening is forecast to be 25 to 30 mm. Freezing levels are expected to decrease through the weekend.

Peak flows for the Lillooet River are forecast for Saturday night or Sunday morning in the range of 680 to 780 m3/s.

The public is cautioned to stay clear of rivers during rain events due to quickly flowing water and potentially unstable riverbanks.

The River Forecast Centre will continue to monitor conditions and will provide an update on Friday.
