Southern B.C. remains in severe drought despite recent rain, with low lake levels, weak river flows and growing water-supply concerns.
Recent rain has done little to ease water worries
VICTORIA — Rain has arrived in parts of southern British Columbia. However, the region is still facing deep drought.
The latest water-scarcity update from the River Forecast Centre shows that the problem remains serious. In fact, many groundwater wells across the southern Interior still have very low water levels.
Meanwhile, several major lakes and waterways are also under pressure.
Okanagan lakes remain at record lows
The situation is especially concerning around the Okanagan.
Both Kalamalka Lake and Okanagan Lake remain at record-low levels. As a result, fish and other aquatic life could lose vital habitat.
Recent rain has not changed the picture much.
In the Okanagan watershed, streamflows remain critically low. Many smaller tributaries are still far below the levels needed to support healthy aquatic ecosystems.
At the same time, the main lake levels remain unusually low.
Rivers are still running well below normal
The drought is also affecting key rivers and creeks.
Flows in the Similkameen and Tulameen rivers remain well below normal. Hedley Creek is also running low.
More importantly, these waterways have shown little response to recent rainfall.
That raises concerns about water supplies in communities across the Thompson-Okanagan.
Water restrictions remain in place
Because of the ongoing shortage, some water-use limits remain active.
Orders are already limiting water use in the Salmon River and Bessette Creek watersheds.
In addition, voluntary irrigation shutoffs have been in place since August in the Lower Nicola, Upper Nicola and Coldwater river watersheds.
These measures aim to protect limited water supplies and reduce pressure on local rivers.
Much of southern B.C. remains under drought stress
The provincial drought portal continues to show high water-scarcity levels across several southern Interior areas.
These include the Okanagan, Nicola and Coldwater river regions, as well as the Similkameen.
Furthermore, September has been drier than normal across much of B.C. Some parts of southeastern B.C., however, have received rainfall closer to normal.
Even so, the recent rain has not been enough to reverse the larger water shortage.
The dry spell is far from over
For now, southern B.C. remains locked in a difficult water situation.
Rain can help. However, the latest data show that short bursts of precipitation are not enough to quickly restore groundwater, lakes and rivers.
As a result, water conservation remains important while communities continue to face low water levels across the southern Interior.
