The River Forecast Centre has issued a High Streamflow Advisory for the Lillooet River, including:
- Pemberton
- Lillooet Lake
- Lillooet River and tributaries
A province wide heat wave is in effect, with Pemberton reaching 37.1°C on Monday. The Lillooet River watershed is comprised of very high elevation snow and glacial contributions which delay peak flows into summer.
With hot weather in the forecast for this week, the Lillooet River is expected to continue to rise and will likely reach above a 2-year return period flow at Pemberton. However, flows are not expected to reach the same levels as seen last year during the Heat Dome.
The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period. The River Forecast Centre continues to monitor the conditions and will provide updates as conditions warrant.
