Flow Information

Did the Order Work?

In August 2019, as once again Koksilah River flows reached critically low levels (0.18 m³/s), the province restricted water use for the irrigation of forage crops such as hay and corn. Following the drought work a study was undertaken to find out if the order had been effective and it was determined that flows increased by about 50% (0.31 m³/s ) by early September.

Koksilah River Flow Data

Publicly accessible real time and historic measurements of water levels and flow are available for the Water Survey of Canada monitoring station located near the Koksilah Road bridge. https://wateroffice.ec.gc.ca/ Keep in mind that these measurements require manual calibration so they are labelled "provisional" (unverified) until the calibration is complete (final). i.e. If the line is green or yellow, the data is provisional. Disruptions to the water flow around the gauge can impact real-time accuracy.

Estimated flows based on the Water Survey data are also compared to long term historical flows for that day and are expressed as a percentile. Click here to see current Koksilah flows http://watermonitor.gov/naww/index.php

• A streamflow which is greater than the 75th percentile is considered above normal
• A streamflow which is between 25th and 75th percentiles is considered normal
• A streamflow which is less than the 25 percentile is considered below normal
• A Streamflow which is less than 10 percentile is considered much below normal
• The flow category Low indicates that the estimated streamflow is the lowest value ever measured for the day of the year

This means, for example, a river discharge at the 90th percentile is equal to or greater than 90 percent of the discharge values recorded on this day of the year during all years that measurements have been made. The Koksilah River seasonal summer low-flow data are available from 1914 to 1916, 1955 to 2011, and 2013 to 2018.
