The water level plot uses the Environment Canada Water Office’s Hydrometric Hourly Data File for station 02KF005 (Britannia1). This data is updated every 2 hours from April to October, and every 4 hours from November to March. Please note that occasional data gaps may occur, which are indicated by periods of constant water levels over multiple time intervals.
Depth values of "99999 m" means that water level data is not available.
1 It is worth noting that the Britannia Station water level and flow metering station is located at NSC!
