Where'd the Otonabee River go?...


Well, it has finally happened. All the Maude Barlows and Tim Shahs of the world were right all along about the water crisis. Peterborough has run out of water.

I kid, of course. But considering the state of the Otonabee River over the past few weeks, it wouldn't be too surprising.

I was probably as surprised as anyone else when I walked downtown by the waterfront to find a dainty little stream where the mighty Otonabee River used to be. The water levels were down drastically, as the few small islands of the Otonabee all of a sudden looked like overbearing mainland. Worst of all -- aesthetically, at least -- was the unfortunate state of the exposed ground that had formerly been river-bottom. The weirdly coloured muddy surface was not a particularly desirable replacement for the river.

But more of a problem was the fact that there was very little water left. So where did it go?

Well, as it turns out, some emergency repairs had to be done on one of the locks south of Lansdowne. Clearly the necessary repairs warranted more than a couple folks hopping in with SCUBA gear with a hammer and nails in hand, so the federal authorities (who manage the lock system) decided to drain the thing. Apparently, this involves draining the river several kilometres upstream, too.

The pictures I've included are from outside my house just north of downtown on the Otonabee. The river was down between two and three metres and looked considerably different. Some islands have been exposed, a big patch of mud lies covered with seagulls and ducks and the river's edge has a tidal feel to it. The river looked much worse farther south. Compare the third with the fourth, which are taken from the same area.

Draining a river several metres is not without its risks. In an interview with the Peterborough Examiner, Trent professor Tom Whillans outlined several of the environmental effects this could have. Many of the concerns are focused on the impacts it might have on wildlife. According to Whillans, all sorts of creatures are at risk, but only if the river bed area freezes for an extended period. Lucky for the fishes and turtles, this December has been usually warm. I knew there was a silver lining to the Tar Sands projects.


The water levels appear to be back to normal now and the timing couldn't be better. The snow is finally coming down and it is expected to stay, for a few days at least.

So the crisis is averted. Phew. That I know our water is OK, I think I'll go water my driveway for the day...
