During the historic high water event in south-west BC on November 14-16th, a number of NHS gauges experienced infrastructural damage and significant channel alterations. As monitoring equipments are re-established and new stage-discharge rating models are developed, the preliminary hydrometric data should be used with caution.

Please note there has been a delay in the publication of some new data to the Historical archive. New data may not include annual statistics such as peaks and extremes at this time; these will be published as soon as possible.
