River Conditions Forecast

This is the first of a series of daily Ottawa River reports we will be issuing for the spring season. All major reservoirs in the system are continuing to empty in preparation for the freshet. Water levels and flows on the main stem of the Ottawa River from Pembroke down to the Montreal Region are expected to remain fairly stable this coming week.
