Data and Graphs

These pages provide links to graphical and/or tabular viewing of the following data:

Automated Snow Weather Station (ASWS) data: Map access to near-real-time data. ASWS relay data from remote sites via GOES satellie every one to three hours. Snow Water Equivalent data are extracted for each site and plotted with comparisons to previous years' data. The near-real-time data are transmitted without verification from remote sites and posted without checking and are therefore liable to major errors and equipment failures. Data available include hourly temperatures, cumulative precipitation, snow depth and snow water equivalent.

Manual Snow Survey Code List

Code Description
A Sampling problems were encountered
B Early or late sample
C Combination of A and B
E Estimate based on areal average
N Scheduled, but not measured
P Estimate based on snow pillow data
R Estimate based on regression
T Trace Amount
U Unscheduled or out of sampling window
Z Preliminary data - not approved

Manual snow surveys are conducted up to eight times per year around the beginning of every month from January through June with extra measurements at mid-month in May and June.

River Level and Discharge: River level and discharge data are collected by the Water Survey of Canada, through the Federal-Provincial cost share agreement. This page links to the Water Survey of Canada's "Real-Time Hydrometric Data" website, from which current water level and discharge information from selected hydrometric stations throughout BC can be accessed. The data are transmitted from the hydrometric station via GOES satellite or telephone telemetry every one to three hours.

Important note for day/time stamp in the near-real-time data: The day/time stamp in the near-real-time data is in Greenwich Mean Time (GMT/UTC). To convert to Pacific Standard Time (PST), subtract 8 hours. To convert to Pacific Daylight Time (PDT), subtract 7 hours.
