STATUS: Active, Real-Time
ABOUT THIS DATA:
The hourly, geodetic water level and flood onset for the Rideau River at Becketts Landing stream gauge (PC-02LA010). Gauge owned/operated by Parks Canada. Statistics have been generated by the RVCA from the period between 1989-2019 (30 years). These statistics include the daily median (50th percentile) and interquartile range (data range between the daily 25th and 75th percentiles). The median and interquartile range represent the typical normal water levels observed at this time of year over the historic record. Flood onset levels for the Hilly Lane / Rideau Glen region represent the estimated threshold at which homes or infrastructure may be subject to flooding. In addition, regional daily precipitation values have been included on the secondary axis.
