STATUS: Active, Real-Time
ABOUT THIS DATA:
The hourly, peak geodetic water level for the Ottawa River at Hull stream gauge (WSC-02LA015). Gauge owned/operated by Water Survey Canada. Statistics have been generated by the RVCA from the period between 1999-2019 (20 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. In addition, regional daily precipitation values have been included on the secondary axis.
