High Streamflow Advisory issued for Squamish River
10:30 a.m. - The BC River Forecast Centre is issuing a High Streamflow Advisory for the Squamish River near Brackendale, and surrounding creeks and tributaries.
Overnight heavy rainfall from 60 - 75 mm over Howe Sound and the Squamish river watershed, and snow melt due to warm temperatures, have caused rapid rises in the river. The current and forecast flow conditions include:
- Squamish River near Brackendale (08GA077) is flowing at 1771 m3/s, which is a 5-10 year return period flow, and is forecast to increase to 2220 m3/s today, a 10-20 year return period flow.
Environment and Climate Change Canada forecast about 10 mm rainfall for today over these regions and river levels are expected to rise slightly and be stable this evening. A break in the rain is forecast overnight tonight into Thursday which should allow the rivers to stabilize and then recede.
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 Wednesday.
