<dl><dd><i>Built in 1985, the CCGS Samuel Risley does icebreaking duties and buoy tending. Her home port is Parry Sound, ON.  During the last week of December, 2010 the Risley has been stationed out of Dieppe (Windsor waterfront, ON), monitoring the Detroit River for the amount of ice coming in off of Lake St Clair.</i></dd></dl><dl><dd><i>Large pans of sheet ice (several inches thick) come in off of Lake St Clair and travel down the Detroit River. Along its 32 mile length, the river ranges from 1/3 to 4 miles wide. In wider stretches (like the one shown in details) the ice is not a problem, but around the 21 islands and river bends, and in the narrower dredged channels the pans jam up and can freeze solid if not cleared.</i></dd></dl>
