UPDATED3 (28-5-2011): Bow River at Calgary Water Levels Rising (Canada Water Survey)

UPDATE:


Below is a screenshot of the selection tool to review water level data from selected sites. An easy and quick reference to current status of listed watercourses.

Below are two graphs.


The first is the typical annual cycle of the discharge/flow of the Bow River as measured at Calgary.  As you can see the peak is concentrated at the late May early June time period, the time when our region gets the most rainfall and snow melt combined.






The second and third graph is the actual raw water level as measured in real time at the Bow River At Calgary (and At the Carseland Weir) hydro-metric station(s).  The dramatic increase in water level is evident on the right of the graph(s).


UPDATE3:  added new graphs below.  The water levels have leveled and/or slightly decreasing.  An interesting anomaly is the spike in the flow on the Carseland Weir station.  To me this suggests they allowed for a managed release to possibly relieve some of the pressure upstream.
