From Mattawa down to Lac Coulonge, levels are expected to begin rising again over the next few days due to increasing flow from reservoirs in the Abitibi-Timiskaming area. Along the Ottawa River below Lac Coulonge, levels are expected to remain stable or slowly decline over the next few days at all locations. This initial peak levels due to natural spring runoff from the west-central portion of the basin has now been reached on the Ottawa River. However, levels are expected to remain high over the next two weeks, as a minimum. Further flooding is possible in the event of significant rainfall events during this period of time. With warmer temperatures, reservoirs in the Abitibi-Timiskaming area are rapidly filling with increased snowmelt runoff. In this part of the watershed, the volume of spring runoff exceeds the capacity of most reservoirs and excess water will be released from the reservoirs once filled.
… and coming…
