River Conditions Forecast

Last Update: 2025-04-25 4:55 PM
Next Update: 2025-04-26 4:00 PM

Significant rainfall is expected over the entire watershed over the next few days. Rainfall runoff and snowmelt water from the northern part and mountainous areas of the basin will combine to increase spring flows in the Ottawa River. Minor flood levels are expected to be exceeded in flood prone areas along the river from Pembroke down to the Montreal Region, starting tomorrow. Levels may exceed the major flood level from Lake Coulonge to Lake Deschenes depending on the precipitation received and rapidity of snowmelt. Please refer to the forecast section of our website for more information about the water levels expected in your area. Levels are expected to peak starting Tuesday-Wednesday at Lake Coulonge, Chats Lake and Lake Deschenes to maximums of 108.50 m, 75.70 m and 60.15 m respectively. From Gatineau (Hull Marina) down to the Montreal Region, levels are expected to exceed minor flood levels but should remain below major flood levels. For the Hull and Thurso locations, levels are expected to reach an elevation of 44.10 m and 42.50 m later next week.

About this map

This map includes markers representing the location of gauges where information on flows and water levels are available. Data collected at gauges shown on the ‘River locations only’ and ‘Reservoirs only’ maps is used for the integrated management of the principal reservoirs within the Ottawa River Basin.

Instruction:

The coloured markers on this map depict conditions (level or flow) as a range of conditions categorized in three groups:  for normal conditions,  for above normal,  for below normal. The marker is  when the current day’s value or percentile are not available.

Click on any marker to see the most recent data from this location and what type of data is measured there. To view data related to the principal reservoirs in the basin, select ‘Reservoirs only’ in the upper right corner. Near real-time and historical data is available for additional locations by selecting ‘Graph View and Advanced Data’. Water levels at 24:00 means at midnight.

Terms of Use:

The data provided by this web service may not be reproduced or redistributed.  Contact the Ottawa River Regulation Secretariat (see Contact us) for information on how to obtain historical data directly from the data owner.

Users of flow data and water level data shown on this website are cautioned to consider the unverified nature of the information before using it for decisions making.  Please see the Disclaimer for further details.

The flow rate and actual levels can change rapidly without warning, particularly during the freshet period. We advise those using bodies of water to exercise caution and to follow safety rules at all times.

Understanding Range of Conditions:

The three ranges are based on percentiles, which are computed from the observations of the current day of the year over the last 30 years. The percentile (P) is the percent of all data that is lower than the actual value for the current day of the year.

 : Normal conditions, between P25% and P75%

 : Above normal conditions, P is equal or greater than P75%

 : Below normal conditions, P is lower than P25%

: Current day value or percentile not available
