Drought conditions persist across southern B.C. despite recent rainfall
Groundwater wells remain exceptionally low and lake and stream levels are still at record lows, prompting water-use limits across several watersheds.
The River Forecast Centre reported that British Columbia's southern Interior faces "entrenched" drought conditions, with high water scarcity levels persisting across the Okanagan, Nicola, Coldwater, and Similkameen river areas.
September has been drier than normal across much of British Columbia, while groundwater monitoring wells continue recording "exceptionally low water levels" despite recent rainfall across the region.
Kalamalka and Okanagan lakes remain "at record-low levels," creating concern about salmon habitat reduction, while streamflow in the Okanagan watershed remains critically low for aquatic ecosystem needs.
Orders limiting water use are in effect for the Salmon River and Bessette Creek watersheds, while voluntary irrigation shut-off measures have been in place since August for the Lower Nicola, Upper Nicola, and Coldwater river areas.
Flows in the Similkameen and Tulameen rivers and Hedley Creek remain well below normal with little response to rainfall, sparking concerns for drinking water availability in Thompson-Okanagan communities.
