An Ottawa diver who was filming his search for antiques at the bottom of the Rideau River found a surprising amount of trash below the surface.

Some 3.2 million litres of raw sewage and rainfall runoff spilled into Winnipeg's river system last month but the incident was unusual only in scope. The amount -- more than an Olympic-sized swimming pool -- was one of the largest spills in years, but was one of about 20 such events that occur each year.
It might feel like the Grand River is an ever-constant, natural connection to our rural past as this region grows and urbanizes. But look a little more closely, and you'll see a river that's constantly evolving. We have left our imprint on the river, just as much as it's left it's imprint on our region.
