VICTORIA – Rivers in a large portion of the province
continue to experience low streamflow conditions. In some areas, these continue
to be record-low flows for the date.
Current
B.C. Streamflows:
The current low streamflow situation results from an earlier than normal
snowmelt in mid-May, followed by continued drier and warmer than normal
weather. Rainfall in most areas of the province was only 30 to 70 per cent of
normal for June and July, and less than 50 per cent of normal during August and
September. With the exception of some coastal areas, rainfall in the first 10
days of October has been marginal. Most rivers throughout British Columbia
continue to be well below their long-term median flows and many rivers continue
to experience record-low flows for the date.
Environment Minister Barry Penner urges all
British Columbians to help conserve B.C.’s water resources. For tips to reduce
water consumption, please refer to the ministry’s website at www.env.gov.bc.ca/wsd/plan_protect_sustain/water_conservation/index.html.
The following basins are experiencing significant low flows:
·
Peace
River
·
Fraser
River (upper and mid-Fraser)
·
Thompson
River (including the Nicola/Coldwater)
·
Nechako
River
·
Skeena
and Bulkley rivers
·
Similkameen
River
·
Vancouver
Island and the South Coast
Many rivers are experiencing record or near record low flows for the
date, including:
·
most
gauged rivers in the Peace
·
Fraser
River at Hope
·
Fraser
River at Prince George
·
Thompson
River at Spences Bridge
·
North
Thompson River at McLure
·
Coldwater
River
·
Eagle
River (at Malakwa)
·
Salmon
River (at Salmon Arm)
·
Quesnel
River
·
Bella
Coola River
·
Saloomt
River (at Hagensborg)
·
Tulameen
River
·
Chilliwack
River
·
Vancouver
Island (west coast) rivers
·
In
general, these rivers appear to be near 50-year to 100-year low flow levels.
Water Supply and Streamflow Outlook:
The 2006 summer drought is persistent and rivers in the above-noted
areas will continue to experience very low flows until significant and
prolonged rainfall occurs. Most of the B.C. Interior is approaching freeze-up,
with night-time temperatures now falling to below freezing at many of our snow
pillow sites. If significant rainfall does not occur in the next month,
precipitation may occur as snow, and rivers will remain at their low levels for
the duration of the winter.
Environment Canada is forecasting light or scattered rain for the southern
half of the province over the next week. However, significant and prolonged
rain is not in the forecast. British Columbia is currently experiencing mild El
Nino conditions, with a resultant tendency for warmer than normal and drier
than normal conditions for the autumn and winter.
