Current Issues
The channel's impact on the Don River is varied. Both sides of the channel are lined with concrete dock wall which creates a barrier and provides little habitat for fish and other water dwelling creatures. The Don is home to about 21 species of fish. Only about four or five species can be found near the mouth. This is partly due to poor water quality but also due to lack of habitat. The dock wall continues, mostly unbroken north to Riverdale Park. In contrast the Humber River which has a natural mouth is home to about 44 species.
Another problem affecting the channel is floating debris that is washed down the Don. Mostly logs and dead wood, there is also an assortment of garbage that collects in the channel. The TRCA corrals this material with a boom across the channel. There can be quite a bit of flotsam especially after a big storm.

Famous quotes containing the words current issues, current and/or issues:
“The work of the political activist inevitably involves a certain tension between the requirement that positions be taken on current issues as they arise and the desire that one’s contributions will somehow survive the ravages of time.”
—Angela Davis (b. 1944)
“I have come to believe ... that the stage may do more than teach, that much of our current moral instruction will not endure the test of being cast into a lifelike mold, and when presented in dramatic form will reveal itself as platitudinous and effete. That which may have sounded like righteous teaching when it was remote and wordy will be challenged afresh when it is obliged to simulate life itself.”
—Jane Addams (1860–1935)
“The hard truth is that what may be acceptable in elite culture may not be acceptable in mass culture, that tastes which pose only innocent ethical issues as the property of a minority become corrupting when they become more established. Taste is context, and the context has changed.”
—Susan Sontag (b. 1933)
