Mid-April Spring Conditions Overview in the Ottawa River Basin

Bulletins posted on 2020-04-23 by Ottawa River Regulating Committee

The Ottawa River Regulating Committee continues to monitor the Ottawa River basin closely as the spring freshet progresses. Reviewing river conditions over the last few weeks, it is now apparent that the peak levels observed between April 8th and April 15th constitute the first peak of the Ottawa River. This first peak typically occurs as the local tributaries in the unregulated portion of the basin lose the bulk of their snow cover, which has now happened. A typical pattern for the spring freshet on the Ottawa river sees a second peak, as snowmelt runoff water from the northern portion of the basin flows down the main stem of the river. This report provides a summary of current mid spring Ottawa River basin conditions and expectations for river flows and levels over the remainder of the freshet.
