UPDATED WITH WATER LEVEL FORECAST FOR 23-MAY THROUGH 27-MAY. Please note that with the flows and tides currently dropping we will update if and only water levels are predicted to rise substantially.
The Province of BC issues forecasts of water levels along the Lower Fraser River during periods of heightened flood threat. The forecasts, descriptions of the tools used in the development of the forecast, and the limitations and caveats associated with them can be found here.
If you follow our blogposts – you’ll know that at Ebbwater we love maps, and we love QGIS. So, we thought we’d take the flood forecast, which is presented as a table, and quickly turn it into a map. Click on any of the markers (which denote gauge locations) to see water level projections for the next 5 days. Enjoy.
Please note that this is a simple exercise, and should be used for information only. The Province’s forecast data (see above) should be consulted for confirmation. Further, all the limitations to the model forecasts apply here too.
The floodplain extents on the map are estimated. The process we used to develop the floodplain can be found in this blogpost. We’ve also added the dikes to the map – the original dike layer was downloaded from GeoBC and attributed with dike assessment information that can be found in this report. Please note that the dike assessment was conducted in 2014, and should be treated with caution as some dikes have been upgraded since.
