1 The water level is calculated as the difference between Britannia4 station's 57.9 m datum and the latest value in the Environment Canada Weather Office's Data File for Britannia4, updated every hour (Apr-Oct) and 4 hours (Nov-Mar).
Note to racers: The BYC gates must remain in place until the water level drops below ~59.0m or less than 1.1m above the datum.
2 Weather data is collected every 5 minutes by the NSC-owned Davis Vantage Pro2 Weather Station, mounted on the lighthouse at the harbour entrance.
Note that: (1) the wind at NSC is likely to differ from that elsewhere on the lake and at the airport, and (2) "No current data" is displayed whenever the application evaluates that, for whatever reason, no new data is available.
3 The current and forecast values at the Ottawa Airport are extracted every 5 minutes from the Ottawa (Kanata - Orléans) City Page. Wind speeds are converted from km/h to kn (knots), and distances from km to nm (nautical miles).
4 The Britannia water level and flow metering station are actually located at NSC!
ISO Abbreviations: kn stands for knot(s), where 1 kn = 1.85 km/h, and nm stands for nautical mile(s).
