Williston Reservoir Forecast – December 18, 2023

Please see the latest forecast from BC Hydro for the Williston Reservoir as of December 18, 2023:

Summary:

The Williston Reservoir is currently 2,177.1 feet

• The typical reservoir level for mid November is approximately 2,186 feet (666.2 m)
• Comparison: November 2022 Williston Reservoir was approximately 2,175.6 feet (663.1 m)

Williston inflows have been below average for two years in a row. This is believed to be from a below average spring 2023 snowfall and the drought.

As a result, BC Hydro is forecasting Williston may approach a spring 2024 level below 2,147 feet.

Lower reservoir levels introduce additional challenges for local interests. BC Hydro will continue to work with First Nations, Local Governments and other stakeholders to identify risks.
