River conditions forecasts posted on 2023-10-25 by Ottawa River Regulating Committee

Levels and flows are above normal at most locations on the main stem of the Ottawa River following precipitation received in the northern portion of the basin earlier this month. Forecast precipitation in that part of the basin will bring additional runoff that is expected to increase flows and levels at most locations on the main stem of the river over the coming week. Levels are expected to remain below minor flood levels in all locations on the main stem of the river, with levels at Mattawa expected to vary between 153.5 and 153.9 metres.
