This is the cross section where the measurement was made and the line we strung across the river, marked with flagging for visibility. In slow velocities, the line helps control the speed of the boat as it is moved across the channel.

This is the view upstream of the cross section.

A manned boat is used to ferry the ADCP back and forth across the river. The velocities at this section were quite slow, and the line across the river allowed better control than driving the small boat.

As schools close for the year and summer weather beckons, many recreationalists head to the Great Lakes' public beaches. However, these coastal areas can become contaminated with disease-causing bacteria that threaten public health, disrupt water recreation, and pay a toll on the Great Lakes economies that depend on summer tourism.
