As of 0800 today, the water at North Service barricade is about a meter closer to the bottom of the slope than it was at the highest water two weeks ago. That means no access is practical, not even to Yves’ marina, and there are no serious options for using our boat or canoe. There is no convenient way to reach the outer areas, as water is now three feet deep in the picnic area, on the access road past the culverts, and in front of the trail shed. Water will also surround the interpretive center, and be up two feet inside the work shed.
Al and I (and Steve, if he feels safe in an inflatable) may paddle out as the weather clears to inspect for lost items. In the longer term, if access to the marina area returns, I might go in and bring the jonboat and engine back to the marina so that some of us can go in and clean the mess in the immediate area of the interpretive center.
The Ottawa River Regulation Planning Board’s last press release is clear, and is even more true today: reservoirs are full, and at this point, the water is expected to rise further, regardless of weather conditions, as the spring freshet has begun.
OTTAWA/GATINEAU, Friday April 28, 2017 –The Ottawa River Regulating Committee cautions that water levels and flows along the main stem of the Ottawa River between Mattawa and the Montreal region will remain high for a sustained period of time. Well above normal April precipitation combined with snowmelt runoff have resulted in recent peak levels not seen in the last 20 years in many locations. Current meteorological forecasts are calling for additional rainfall of 30-60 mm over much of the Ottawa River basin. This additional precipitation is expected to once again increase levels that had been in decline.
Current weather forecasts predict very significant precipitation beginning Sunday, April 30th into Monday, May 1st. These weather conditions could cause rapid increases in levels and flows between Mattawa and the Montreal region. The increase in levels and extent of possible flooding will depend on the amount of precipitation received, the tracking of the storm as well as the amount of snowmelt in the north.
With current forecasts, northern snowmelt runoff combined with precipitation is expected to fill most northern reservoirs in the next few days. As a result, the capacity to retain additional runoff from the headwater areas in the north will be diminished.
