River Forecast and Snow Surveys: Interpretation and Commentary

Staff at the River Forecast Centre analyze the snow, meteorological and hydrometric data as they become available. Several documents are produced each year which are available through this page.


Snowpack and Water Supply Outlook

(The Snow Bulletin). Snow Surveys are conducted at the beginning of each month from January through June, with small additional surveys on May 15 and June 15. Once the data have been collected, a province-wide and region-by-region analysis is made of the snowpack and water supply outlook. Included with the analyses are graphs showing regional snowpack indices. This page is normally updated about four working days after the nominal snow survey date.


Commentary on Seasonal ASP readings

Seasonal ASP graphs are updated daily during the period from October through July. A brief summary and comments are provided throughout the spring after the data have been updated at the beginning and middle of the month.

Water Supply and Streamflow Conditions

Comments on any dry or low water supply conditions existing or forecast for B.C., with links to relevant federal, provincial or North American sites.
