High Water

2019 May 01

The local rivers are running high. Both the Ottawa and the Petawawa are above or near record levels.

The control dam at Rapides des Joachims is essentially wide open even though the head pond is perhaps six feet below summer levels. They need the capacity to catch the massive outflows expected from central Quebec that are still to come.

For a while, the Petawawa River was threatening the bridge in the Town of Petawawa, prompting its closing. However, by dumping large quantities of blast rock down the shore embankment, they have stopped the shore erosion and the bridge has reopened.

The Dumoine Road Bridge at Rapides des Joachims (da Swisha). The flow here is from the control dam. (April 30)

Looking downstream from the Dumoine Road Bridge with da Swisha barely visible in the background. I think, but I'm not certain, that the hill in the extreme distance is Mount Martin opposite Deep River.

In the summer, this is placid water; there is essentially no flow. All of the river is flowing through the hydro dam. Water flowing in this channel is "wasted".

The local white-water guys have painted river depth markings on the near pier. Not much use at these levels.

Lovers Rapids at Centennial Park in Petawawa. The park is closed; this is as close as we could legally get. The horizontal feature just below center is a stone retaining wall (the catwalk) that diverts the river away from the park. The "hump" in the middle of the river at the top is bedrock that people sunbathe on in summer. The main channel, with the big rooster tail at lower water levels, is on the near side of that outcrop with less flow on the far side.

Point Rapids (Golf Course Rapids). This is a fun little beginners play rapids in the summer.
