For quite some time, the Great Lakes -- from Superior to Ontario -- have been at historically low water levels. So many people were surprised this week that regulators are lowering the gates at the Iroquois Dam near Ogdensburg because the St. Lawrence River is too high.
A new global observation technology has been developed to help recreational boaters on the St. Lawrence River.
This new tool, developed by New York Sea Grant and the Great Lakes Observing System, allows recreational boaters to access information about the river's current as well as water depth. Dave White with New York Sea Grant explained how this technology works.
