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: 2024-07-09 2:28 PM
Next Update: 2024-07-16 4:00 PM

Levels and flows are above normal for this time of year in many locations along the main stem of the Ottawa River. Upstream of Chats Lake, levels and flows are expected to remain relatively steady or decline slightly over the coming week. Downstream of Chats Lake, levels and flows could increase briefly in response to heavy rainfall over the coming days. Levels and flows are expected to decline following the rain. Please note that weather forecasts can be wrong. Heavier than forecast rainfalls can occur with very little advance warning, and can result in rapid changes to water levels and flows.
