Ottawa River Regulation Planning Board

The Planning Board was established to ensure integrated management of the principal reservoirs of the Ottawa River Basin:

  • to reduce flood and drought impacts along the Ottawa River and its tributaries, all the way down to the Montreal Region
  • while maintaining beneficial water uses in the basin.

River Conditions Forecast

Last Update: 2024-04-14 3:56 PM
Next Update: 2024-04-15 4:00 PM

Significant rainfall (up to 75 mm) was received in the Abitibi-Timiskaming area between April 11 and 13. This event melted most of the remaining snow, which increased the amount of runoff. The combined effect of rain and snowmelt caused inflows in that part of the basin to increase very rapidly. Water levels and flows along the main stem of the Ottawa River from Mattawa down to Lac Coulonge have increased rapidly as a result. Moderate precipitation amounts (15- 40 mm) elsewhere are causing levels and flows to increase gradually. Flows and levels are expected to continue increasing over the next few days from Pembroke down to the Montreal Region and should start decreasing later this week. Minor flooding in low-lying areas may occur over the next week. Low-lying areas are those locations that regularly flood during the spring freshet period. See our press release for more information.  Please refer to the forecast section of our website for more information about the expected rate of level increase.
